The brand

About Oat Shoes

Oat Shoes markets its footwear as the world’s first biodegradable shoes that bloom, and the brand states that once you have worn a pair down you plant them in the ground where the Oat Shoes decompose into the earth while a bouquet of wildflowers grows from your old sneakers. The Oat Shoes site does not publish any fibre or material composition, so no specific plant fibre, cork or bioplastic content is confirmed on the brand’s own pages.
Oat Shoes does not disclose its supply chain, as the brand’s site names no country of manufacture and gives no description of how or where its biodegradable shoes are made.
Biodegradability is the core sustainability claim Oat Shoes makes, with the brand describing collections of biodegradable shoes, baby shoes and sustainable footwear and positioning itself at the forefront of sustainable innovation since its foundation in 2010.

Who’s behind it

Sourcing

Getting It

Where this brand isn't perfect

Check firstNot a certified B Corp

Oat Shoes is not a B Corp. The brand-level labels are thinner than the product-level ones.

Skip it ifNo named factories, mills or suppliers; sourcing disclosed only as 'within Europe' (region level); brand appears discontinued/inactive with only historical (circa 2010-2013) information available; claims not independently verifiable today.

Flagged in the sourcing ledger before you buy.

What the label won’t tell you

The questions sensitive skin actually asks, answered

0/0 styles scanned, no sampling 0% plant · 100% synthetic PFAS-free (verified) ✓ read from the live product feed, not the marketing page
?Are there hidden chemicals against my skin?
~9% of people react to formaldehyde, common in wrinkle-free and easy-care finishes.
Oat Shoes is PFAS-free (verified). Dye process on record: Low-impact / GOTS-certified dyes. We record the dye process and chemical flags for every brand.
?Is “100% cotton” actually 100%?
Most “cotton” underwear hides elastane or spandex in the waistband, exactly what sensitive skin reacts to.
We read all 0 styles individually: 0% plant, 100% synthetic. Even the elastics are bio-based, not spandex. We flag any style whose description hints at a trim.
?Is “sustainable” just greenwashing?
“Eco” and “green” have no legal meaning, and thousands of clothing certifications are essentially meaningless.
We scanned 0 styles from the store’s own product feed and publish a score only at full coverage.
?Will the elastic bring me out in a rash?
Latex and rubber in waistbands are a top trigger for contact dermatitis and latex allergy.
0% plant, 100% synthetic across the catalogue means the elastics aren’t spandex. Set your allergy profile and we only show you brands that clear it.
?Am I shedding microplastics onto my body?
Synthetic underwear sheds microplastics into skin and water with every wash.
0% plant fibre, plastic-free, so there’s zero synthetic to shed. Every style read individually, no sampling.
?Where is it really made, and by whom?
“Ethical” brands rarely name the farm or factory, so wage and safety claims cannot be checked.
We publish the full sourcing chain, farm and factory certifications, traceability level and the honest red flags, including where sources conflict. Traceability on record: Country only; factory: Netherlands / Europe (production stated to take place within Europe; specific factory not named).

Sources: consumer research on formaldehyde in easy-care fabrics (~9% of people react), PFAS in water- and stain-resistant finishes, and hypoallergenic underwear for eczema and contact dermatitis.

Oat Shoes, founded in the Netherlands in 2010 by designer Christiaan Maats, made biodegradable sneakers from hemp, cork and a custom biodegradable leather with embedded wildflower seeds, and stated that all materials and production were kept within Europe as a point of pride. However this is disclosed only at the ‘within Europe’ region level, with no named factories, mills or suppliers, and the brand appears to be historical/inactive, so information cannot be verified against current operations.

Sourcing flags & notes: No named factories, mills or suppliers; sourcing disclosed only as 'within Europe' (region level); brand appears discontinued/inactive with only historical (circa 2010-2013) information available; claims not independently verifiable today.

How it was read: Every product listed in the brand's live catalogue is retrieved and its stated fibre composition read individually. From the product page, the store's own product data and its material labels. A fibre percentage is published only when 100% of the catalogue has been read. Items with no clothing textile (gift cards, packaging, jewellery, homeware) are excluded from the percentage rather than counted as a pass or a fail.

Why excluded: Nothing was excluded: every item counted is a textile product.
