15 Best Sustainable Materials for Shoes

In this post on sustainable materials for shoes, we will list sustainable materials that are used in the production of footwear and sneakers. The full list of types of fabric and sustainable clothing fabric, is discussed in this post on 19 Best sustainable fabrics you should know.

Our planet has been used as a giant garbage bin for too long. The fashion industry needs to be put on a sustainable and socially responsible footing, and thankfully we do have choices.

Why Choose Sustainable Materials for Shoes?

Did you know that the average pair of sneakers is made up of 65 components and every single pair, produces more than 13 kg of carbon dioxide emissions. It is therefore imperative to find more sustainable materials for footwear.

There are lots of considerations to weigh up when shopping for new footwear. Apart from it being comfortable, a very important question to ask is, are they sustainably made?

When we look at sustainable materials for shoes, we also need to look at:

  • how the crop was grown,
  • the way in which materials are created, and
  • the production processes that are used,

As these all have an impact on the environment, and thus the sustainability. Using recycled materials is far more sustainable, than creating virgin materials.

Making a pair of sneakers or shoes contributes to water consumption, destruction of the rain forest, greenhouse gas emissions, micro plastic pollution and huge amounts of landfill waste. Let’s list sustainable materials that are available for use in footwear.

Sustainable Materials List

Leather has traditionally been used for footwear and increasingly over the past few decades, we have seen a huge increase in the use of petroleum based synthetic vegan leather. Neither of these are sustainable. The use of chemicals in processing materials, always has a negative effect on the environment, and thus affect the sustainability of the product.

  • Natural fibers
    • Plant fibers: cotton, linen, hemp, bamboo, ramie, coconut, rubber, cork, nettle.
    • Animal fibers: wool, silk and leather
    • Mineral fibers: these come from geological processes like asbestos, ceramic (glass fiber) and metal (aluminum) fibers. These fibers are mainly used in the building and construction industry, so we will not look at them here.
  • Man made or Artificial fibers: These are produced from natural raw materials, but are made with chemical processes that have a varying impact on the environment.
    • viscose or rayon, lyocell, modal, cupro
    • seaweed fabric
    • agricultural waste products such as: pinatex from pineapple, apple, orange, desserto from cacti, mango, grape leather, coffee, mushroom leather
  • Synthetic fibers: These do not exist in nature and are all derived from oil, so are the least sustainable. Virgin plastic like polyester, nylon, polyurethane, acrylic etc. are not sustainable materials as they are made with petroleum. Recycled plastics like recycled nylon and recycled polyester, are on the sustainable materials list. This is because it is made in a closed loop and preventing plastic waste going into landfill, and polluting our water ways and oceans.

Certain fibers like hemp and wool, and of course recycled plastic and leather, can also be used as a sustainable clothing fabric. Here we will concentrate on those used for footwear and list sustainable materials for shoes.

 

1. Cork Leather

Cork leather is made from the bark of cork oak trees. The cork tree, Quercus Suber, is where cork is harvested from, and is actually a collection of dead cells that comes from the bark of the cork oak tree. The cork is harvested without any harm to the tree and is a naturally renewable material, as the cork grows back again after each harvest. Cork leather shoes are on the sustainable materials list

The first cork harvest takes place when the trees are at least 25 years old. The second harvest takes place nine years later, and is the first usable cork harvest, as the first harvest is not usable. After that, harvesting takes places every nine years. Harvesting of the cork bark actually prolong the lifespan of the tree by up to three hundred years.

Cork is eco-friendly and is a completely natural, recurring and easily replenishable material. Cork comes from a sustainable and renewable source and can be recycled. It is biodegradable and at the end of its life cycle, it will break down into the environment.

It is used in shoes and handbags, as well as flooring and furniture. This plant based vegan leather is soft and stylish and has a special feel. It is low maintenance, slow burning, light (cork can float) and elastic. The insulating and hypoallergenic properties means it doesn’t absorb dust, so no problems for allergy and asthma sufferers.

Learn more about the use of cork in shoes in this post on the Ultimate guide to plastic free vegan shoes. Cork leather is also discussed in this post on vegan leather vs real leather.

2. Wool

Inspired by natural materials and the abundance of sheep in New Zealand, a revolutionarySustainable wool shoes from Allbirds wool fabric that is specifically made for footwear, was developed by Allbirds. The wool fabric is made from Merino wool and 60% less energy is used in the wool process, than materials used in typical synthetic shoes.

Merino wool is breathable and let your feet feeling ventilated. This allows you to wear wool shoes without socks. Merino wool also has anti-bacterial properties, so your feet stay healthy, without your shoes developing any odors.

Sneakers made from sustainable wool is produced in New Zealand by Allbirds. They work with the leading organization, ZQ Merino, to ensure that wool is produced to high standards of farming, land management and animal welfare. The wool sneakers are machine washable on a low cycle, to remove dirt and sanitize them.

3. Hemp

When I list sustainable materials, hemp will always be on the sustainable materials list. Hemp is a sustainable plant and grows easily without any chemicals like pesticides, fungicides and herbicides. It is mostly organic, due to the way that help is grown and produced, so leaves a small carbon footprint.

Hemp shoes are eco friendly and breathable and becomes softer with wear, so breaks in well when it is used in footwear. Hemp is hypoallergenic, so will not irritate your skin, and as it is thermo regulating, your feet will not sweat.

The natural anti-bacterial properties of hemp means that it does not hang on to odors like many synthetic materials, thus making it one of the ideal sustainable materials for footwear.

Shoes made from hemp are durable, as hemp fibers are extremely strong. Because hemp is a natural fiber, it will eventually decompose, therefore leaving a very small carbon footprint compared with synthetic vegan leather.

The benefits and properties of hemp for footwear, are also discussed in this Ultimate Guide to the best hemp shoes.

4. Natural Rubber

Natural rubber is made from latex, that is obtained from plants and predominantly the rubber tree. Natural rubber from plants is eco friendly. Harvesting the latex and using natural rubber has a low environmental impact and after tapping, the tree heals naturally.

The rubber tree is an ecological, sustainable crop, and helps to maintain the global carbon balance in the atmosphere. More than half the rubber that is harvested, is used in the automotive industry, but rubber is also used in the footwear industry. The most popular use of natural rubber in footwear, is for the soles of shoes, but it is also used to make wellington boots and flip-flops. You can read more about it in this post on Best Natural Rubber flip-flop sandals.

Natural rubber is biodegradable and can be recycled at the end of its life.

5. Recycled plastics

It is no longer necessary to use Polyurethane, an unsustainable plastic derived from petrochemicals, in footwear, as recycled plastic can now replace it. The normal procedure for recycling PET plastic bottles, Vivaia recycled plastic shoesit to collect plastic waste from our streets, beaches, waterways and oceans.

The bottles are then cleaned, shredded and melted. The melted liquid is pushed through spinnerets and converted to yarn. It is then ready to be used for weaving or knitting the uppers for shoes and sneakers.

Vivaia is a brand that produces knitted uppers for their shoes from recycled plastic.

Recycling reduces the amount of plastic trash and also gives the non-biodegradable plastic a second life. This is far better than using virgin plastic like polyurethane. By repurposing plastic waste, we have less plastic pollution.

Uppers made from recycled plastic canvas are eco friendly, breathable and flexible.

Look out for the best sneakers made of recycled plastic here and also the best 7 flip-flop sandals made from recycled materials. Recycled plastic is one of the best new sustainable materials for shoes.

Recycled plastic is also used to make swimwear and outdoor clothing like windbreaker jackets.

6. Natural Leather

Because of the chemicals used in the tanning process, natural leather is not on the sustainable materials list when it comes to sustainable materials for footwear. So one has to look for vegetable tanned leather to make sure that it is sustainable. But there are sustainable and cruelty-free replacements for natural leather.

Replacing animal leather is possible and there are several possibilities, including fish skin leather, leather made from apple skin, grape leather and mushroom leather, and others that are less common like mangoes and cactus leaves.

7. Fish skin leather

Leather can be made from almost any skin and that includes making fish skin leather. Fish skinfish skin leather is on list sustainable materials leather is made from skins of non-endangered fish species including salmon, shark, carp, bass, sturgeon and catfish, with salmon being the most common fish that is used for leather made from fish skins.

The fish leather industry is still small scale and many make use of a circular economy. It means that many of them are quite secretive about the processes and materials that they use. Both washable salmon leather and vegetable tanned leather are produced.

Although fish skin leather is not vegan, it is sustainable. Salmon skin leather is more eco friendly than traditional leather.

This is where you can read more about the production of fish skin leather.

8. Desserto Cactus Leather

Leather made from cactus is the latest eco friendly vegan leather fabric. The leaves of the nopal cactus, also known as a prickly pear plant, is used to make the leather. When I list sustainable materials for shoes, cactus leather is definitely very close to the top in terms of sustainability and being eco friendly.

Cactus leather is organic, soft, durable, breathable,Desserto cactus leather is used to make shoes and boots elastic and partially biodegradable.

The cactus plant requires almost no water and grows abundantly throughout Mexico, so it is a stable, abundant supply of raw material. Desserto is a Mexican brand, started by two entrepreneurs, that is using nopal cactus leaves to turn it into organic, natural, cruelty-free leather.

Cacti are grown organically and as it is a native crop, the biodiversity of the area is matched, and blend naturally with the wild fauna and flora.

Harvesting of mature cactus leaves are done every six to eight months. The plant are not harmed when the leaves are cut. The leaves are dried in the sun for approximately three days, so no additional drying process is required.

It contains no toxic chemicals, phthalates or PVC. Desserto is the first leather made from cactus and the material has the potential to create a sustainable vegan leather market. Nothing goes to waste as the remaining organic cactus material that is not used for making leather, is sold to the local food industry or exported.

9. Pineapple leather Pinatex pineapple leather is one of the sustainable materials for footwear

Pinatex is a natural fruit fiber leather alternative that was developed over a period of several years and is the name given to pineapple leather. Pineapple fiber is obtained from the leaves of the pineapple plant, after the pineapples have been harvested. The leaves go through a process of decortication to extract the fibers.

The fibers are degummed and goes through an industrial process to become a non-woven mesh that forms the basis of pinatex. Pinatex is breathable and strong, yet soft and light.

So what is an existing byproduct of the pineapple harvest, is then converted into vegan leather. Pineapple fiber fabrics are also discussed in this post on Innovative Textile Solutions.

10. Mushroom Leather

A vegetable leather, called Muskin, has been developed from wild mushrooms. Muskin is completely made from the cap of Phellinus ellipsoideus, a gigantic, inedible mushroom species which is native to subtropical forests. These mushrooms feed on tree trunks, making them putrefy. By removing them from the trees, it is also helping the trees.

Mushrooms are harvested by hand and dried for up to a year. It is then peeled and hand processed. Although it is an elaborate process, no chemicals are used during the processing, making it nature friendly.

Muskin looks very similar to animal leather, but it is a vegan product which is organic, gluten free and chemical free.

11. Vegea Grape Leather

Grape or vine leather is a vegan leather that is produced using the waste materials from the wine industry. Vegea, comingVegea grape vine leather from VEG for vegan, and GEA for Mother Earth, is using leftovers from the wine making industry, to create a vegan leather.

All the parts of the grape waste, including grape skins, seeds and stalks are used. No toxic solvents, heavy metals or dangerous chemicals and harmful substances, are used during the production process.

The resulting bio material is suitable for use in the fashion, furniture, automotive, transportation and also the packaging industry. Vegea grape leather has a high vegetable and recycled raw material content, such as vegetable oils and natural fibers from the agricultural industry. No chemicals or water is required to produce it and it is Made in Italy.

Vegea grape leather is also discussed in this post on 5 Innovative Textiles Solutions for Vegans.

12. Mango Fruit Leather

Fruitleather, a young Dutch company based in Rotterdam, are using discarded mangoes to transform it into a leather-type vegan material. A mango puree is obtained from the fruit, which is then baked in the oven, to produce small sheets of 40 cm x 60 cm.

The mango fruit leather is completely natural, although there is an option to have a polyester backing. Different leather textures can be obtained by embossing the sheets. When it comes to sustainable materials for footwear, mango leather is quite unique and you can read more about it in this post on 5 Innovative Textiles Solutions for Vegans.

13. Frumat Apple Leather Veerha shoes made from apple peel leather

Apple leather is made from a byproduct of the apple juice industry. Apple cores and apple peels, which is an agricultural waste product, is used to make the vegan leather.

Frumat apple leather is a combination of 50% dried apple powder and 50% polyurethane. So although the apple is coming from a natural renewable source, polyurethane is a petroleum based plastic, thus reducing the sustainability of Frumat apple leather.

When it comes to sustainable materials for shoes, this is low on my sustainable materials list. This post on 5 Innovative Textiles Solutions for Vegans further discusses the applications of apple leather.

14. Coffee

A Japanese footwear brand, Cchilu (pronounced Chee-Loo) has developed a green technology called XpreSole, to make shoes from spent coffee grounds (SCGs). Innovative textile solutions with fabric made with coffee grounds used in footwearEvery major component in the shoe is made from coffee grounds, incorporating sustainable materials for footwear.

Used coffee grounds are melted and mixed with recycled plastic bottles. This is then turned into a yarn that is used in the woven upper and insole. Coffee is also used in the outsoles.

Shoes are water repellent and five cups of recycled coffee is used to create each pair of XpreSole shoes. By using the coffee fabric, the amount of petroleum based materials are reduced by 30%.

Read more about other fabrics made with coffee grounds and using sustainable technology, in this post.

15. Coconut Coir Fiber

When I list sustainable materials, coconut has to be on there. Coir coconut fiber is a natural cellulose fiber which is obtained from coconut husk. It is the fibrous material that is found between the outer coat of a coconut and the hard internal shell.

Coconut fiber for footwear is on the sustainable material listCoconut fiber is eco friendly and comes from a natural and renewable source, and is one of the latest sustainable materials for shoes.

Coconut coir is often used in the midsole of shoes. Mixed with natural latex it mimics the feeling of having a soft cushion under your foot. Coconut coir midsoles and insoles are lightweight and comfortable.

Flip flops and other sandals are also made from coconut fiber.

The fibers are 100% biodegradable and is hard wearing and durable. Coconut coir fiber naturally absorbs odors and can minimize bad smells without additional treatments and chemicals.

Coir is used in horticulture as a growing medium, as geotextiles, and as carpets and basket liners.

Final Thoughts on Sustainable Materials for Shoes

There are companies that are passionate about preserving our planet for us and for future generations. Fortunately we have a new generation of designers that are actively looking for sustainable materials for footwear, and practices and innovative textiles that respect the planet.

  1. Hey, how are you doing today? I have to say that I absolutely loved reading  your article tonight. I was actually surprised to see that pineapple could be used as leather for shoes. Materials like mushroom, hemp, and pineapple could be great options for people who are vegetarian and want to dress well without any guilt. Do you own any of these types of shoes? And what would you recommend for people on a tight budget? 

    Best regards,

  2. It is refreshing to see that there are companies out there on our planet wanting to make a difference. We recently celebrated Earth Day and these types of sustainable fashion ideas is what we need more of. I’m so weary of even purchasing any new clothing at the stores because of the materials being used and also its just more unnecessary consuming. However with these eco friendly solutions it makes things easier. Hemp has always been a favourite of mine and Im eager to start trying out the others you mention in here.

    Thanks for sharing

  3. Oh dear, you didn’t make it a lot easier! I’ve been looking for a while at shoes that are more sustainable. I don’t like leather shoes, but it’s almost the only waterproof fabric they use these days for shoes. It’s great to know that these materials are sustainable and waterproof. Well, not all of them, but quite a lot are.

    Can you recommend a good option/brand for worker boots?

    Reply
    • Some of the wool shoes that are available from Allbirds is waterproof, so feel free to check them out. Depending on the type of worker boots you need, there are different brands that would specialize in equipment for the building trade.

  4. Your website provided so much rich content on sustainable fabrics.
    I was not aware of the multitude and variety, that can be used to produce footwear, much less any other garments.
    Many of the products are fashionable, and very marketable.
    Thanks for sharing such valuable information, of sustaining our planet.

  5. Your article is very informative on the sustainable materials for shoes. I do try to be as sustainable as possible in my shopping choices. But I have not seen a lot of information how we can be more green on my shoe choices. Please do link to some of your favorite brands of shoes that use sustainable materials. I would love to check them out.

  6. This article was very well written. The in depth descriptions of how different materials are used in the production of shows was great. This article helped open my eyes to the vast ways shoes are made. 

    I also was unaware of the different types of leather that is used. Cork leather, Fish Skin Leather, Cactus Leather etc.. I definitely learned something today.

  7. We never think much about the materials our clothing or footwear is made up of. Not to mention how it will affect the environment when it is thrown away!!!

    Thanks so much for this info on which footwear is more eco-friendly. I think this is something I will consider in the future when I purchase my shoes.

    • We all need to be more aware of how products are made and what goes into them. And then of course how can you dispose of it at the end of its life. These are all factors that affect the sustainability of a product.

  8. Sustainability is key in the changes we need to make. So many products are made using more resources then they replace. it’s all fine and good to have a product that doesn’t cause the consumer to use resources but if the production of that product is exponentially high than what it replaces it’s a fraud and people need to be aware of what it takes to make the things they buy.

    Reply
    • It is a very good way of putting it that many products use more resources than they put back. More people need to be aware of what goes into the products they buy, and how it is made.

  9. There are a lot of things hurting nature in our days – like cryptocurrencies – and we don’t need more factors that add up to that bad practice. I like buying shoes a lot and I have quite a number of pairs in my drawer, but I certainly don’t want that to hurt the nature I’m living in.

    I learned a lot from this read. Great article!

    Reply
    • The footprint left behind by cryptocurrencies depend on whether renewable energy is used or not. But this post is about sustainable materials for shoes. If you don’t want shoes that hurt your feet, you also should not choose something that hurts the planet.

  10. I had zero idea that there were so many sustainable options for shoes. Thanks for the article. A couple of things popped up while I was reading. How much more expensive is it to produce sustainable shoes and do wool shoes shrink? I would think so but I have to ask. Thanks for enlightening me and I will surely look at my shoes differently after today.

    Reply
    • Wool shoes from Allbirds will not shrink and they are machine washable on a gentle cold cycle. The production cost of sustainable shoes depends on the type of material used. Recycled sneakers do not cost more than normal synthetic trainers, but pineapple leather is expensive. So it depends and is not necessarily more expensive. I hope this helps.

  11. It’s more and more difficult to find real leather shoes. I was a bit surprised at first to read that those shoes are not
    sustainable. But I understand what you mean. Since the leather production is a nuisance for our planet. It’s so fascinating to read about shoes made with materials such as cork leather nor hemp. I have never heard about pineapple leather. What a beautiful article!

    Reply
    • Leather is not sustainable if the chemical tanning process is used. Vegetable tanning is sustainable, but only about 5% of leather is made using vegetable tanning, mainly because it is more expensive. But we do have other sustainable choices these days.
