Are Vegan Shoes Sustainable?

Not necessarily, but the better ones are. And often the main questions are: what they're made of and how, and how many pairs you buy. It's about their material composition and manufacturing process, and about minimalist, timeless designs crafted with the quality to last.
‘Vegan’ doesn’t automatically mean ‘sustainable’
Let's start with the fair criticism, because plenty of brands gloss over it. A shoe can be vegan and still be made from virgin plastic. Much inexpensive ‘vegan leather’ is simply polyurethane (PU) or PVC — petroleum-based synthetics that don't biodegrade and can shed microplastics as they wear. Technically, a cheap plastic flip-flop is ‘vegan’ too.
So no, the label alone guarantees nothing. Being animal-free can be just a statement about what a shoe isn't made of; it isn't, by itself, an environmental credential. Anyone who tells you otherwise is selling a story.
And there's more: some of those cheap components aren't very healthy, either. We already know they can act as endocrine disruptors, trigger allergies, or simply not let your feet breathe well — among other properties worth checking in a shoe.
But compared to animal leather, the numbers are striking
Here's the context that criticism often leaves out. Animal leather is not a low-impact material. It's tied to cattle farming — a leading driver of Amazon deforestation and a major source of methane — and its tanning stage relies on chromium and other chemicals that pollute water and soil.
The gap is large. A 2025 meta-analysis of life-cycle studies put the carbon footprint of bovine leather at roughly twelve times that of vegan leather (about 187 versus 15 kg of CO₂ per kilogram of finished material). Other assessments find synthetic leather emits around seven times less per square metre, using far less water and land. Even the most basic plastic-based vegan shoe generally comes out ahead of leather on climate, water and land use.
That doesn't make PU harmless. It means the honest comparison isn't ‘plastic versus natural’ — it's one kind of material versus another kind of material with its own heavy environmental and chemical baggage.
Not all vegan materials are equal
The useful way to think about it is a spectrum. At one end sits virgin PU and PVC — vegan, but the least sustainable option. Moving along, you find recycled synthetics like recycled PET and recycled PU, which give existing plastic a second life. Further still are plant-based materials such as pineapple-leaf fibre and apple leather, which replace much of the plastic with agricultural waste. And at the greener end sit natural materials like cork, which is renewable and biodegradable.
Materials like Piñatex, apple leather, cork and recycled PET aren't perfect — most plant leathers still use some plastic binder — but they sit far closer to the sustainable end than a virgin-plastic shoe does. Where a pair falls on that spectrum tells you far more about its sustainability than the word ‘vegan’ ever could.
The question most brands don’t ask
There's another point, and it reaches past materials altogether: the comforting belief that greener products alone will get us to sustainability. The trouble is the rebound effect — efficiency gains tend to be swallowed up by rising consumption. For example: over two decades, cars became about 50% more efficient, yet the number of cars and the distances driven more than doubled — wiping out what efficiency alone had gained.
Applied to footwear, the lesson is clear: the most sustainable material in the world doesn't help if you buy several pairs a year and bin them each season. Call it sufficiency — buying less, and buying to last — call it whatever you want, this matters as much as what a shoe is made of. A durable pair worn for years, then repaired, will almost always beat a ‘sustainable’ one replaced every few months.
So, are they sustainable?
The honest answer: it depends on the material, the manufacturing process, and just as much on how you buy. A vegan shoe made from recycled or plant-based materials, worn for years and cared for, is a genuinely sustainable choice. A virgin-plastic one bought on impulse and discarded is not — even though both are equally ‘vegan’.
That's the thinking behind how we work at NAE: choosing lower-impact materials — cork, pineapple, apple, recycled PET — over virgin plastic, and designing shoes to be kept, not replaced. If you want to make any pair more sustainable, the simplest step costs nothing: buy what you'll wear for years, and take care of it so it lasts.
Sustainability isn't a label. It's a practice: choosing better and making it last.
