Materials for footwear
Material families and named material records tagged for footwear, followed by related case studies. Tags identify a direction to assess; confirm the specific grade, construction and documented limits before use.
Assess uppers, linings, reinforcements and trims separately. Confirm the component and its use conditions before selecting a grade.
Material families
11 entries- Material family
Apple-waste sheet
The apple pomace is the named input, not the bulk of it: certified bio-based content typically runs 20–55% by weight, with a polyurethane binder and backing making up the rest. Ask for…
- Material family
Cactus-fibre sheet
Two sheets both sold as cactus leather can differ substantially in plant content: the cactus is the differentiating input, the rest a polyurethane system on a textile backing. Definitions are not yet…
- Material family
Lyocell
A generic fibre class, not a brand: the closed-loop solvent-recovery rates published by branded producers do not transfer to an uncertified mill, so ask for its own figure. FSC covers pulp origin,…
- Material family
Organic cotton
Certification fraud has been documented in this category at scale, mostly around transaction certificates. A scope certificate proves the supplier is certified; only an in-date transaction certificate for your own shipment proves…
- Material family
Pineapple-leaf fibre
Plant content is higher than most sheet alternatives, but the resin layer decides wet performance and is the one suppliers describe least. Neither GOTS nor FSC applies to the finished sheet, whatever…
- Material family
Recycled leather
Leather fibre bonded with a polymer binder: both percentages matter and suppliers usually quote only the leather one. An LWG certificate rates the tannery that produced the source fibre, not the bonded…
- Material family
Recycled metal hardware
Often the heaviest component by weight and the one routinely left out of a brand's material claim. Recycled content in metal is well established and cheap to verify, so if your product…
- Material family
Recycled nylon
Where nylon is chemically regenerated (depolymerised and repolymerised), it can be recycled repeatedly without loss of quality; this cannot be assumed for mechanically recycled grades, so ask the supplier which route was…
- Material family
Recycled plastic components
Recycled polymer varies more between lots than virgin material, and small mouldings are where that variance shows first, as brittleness. Ask for the recycled percentage and the lot test; a supplier who…
- Material family
Recycled polyester (rPET)
Most of it is bottle-derived, which is a different argument from textile-to-textile recycling and is increasingly challenged for pulling feedstock out of a closed loop. Post-consumer or post-industrial is the question least…
- Material family
Recycled PU leather
A synthetic sheet with recycled input, often outperforming plant-input alternatives on abrasion and wet-rub while carrying a substantiable recycled percentage. The risk here is the wording, not the material: sold as 'eco…
Named material records
6 entries- Material record
AppleSkin™
The certified bio-based figure is a ceiling across the range, not a per-grade guarantee, and the backing changes between grades while often being left off the specification sheet you are shown. Ask…
- Material record
Desserto®
The cactus input is what differentiates the sheet, not what most of it weighs; the polymer system and backing carry the rest. No single composition figure is published across grades, so get…
- Material record
ECONYL®
Depolymerisation allows repeated recycling without degradation, a genuine advantage over mechanically recycled fibre, but the premium over virgin nylon is large and has held steady, so budget for it rather than waiting…
- Material record
Piñatex® (producer in administration)
The trademark holder has been in administration since August 2025, so treat any offer as remnant inventory and confirm who is actually selling. The widely quoted 80% is a fibre-to-PLA ratio inside…
- Material record
REPREVE®
Bottle-derived recycled polyester draws feedstock out of an existing bottle-to-bottle loop, which does not make the recycled content untrue but weakens a broad circularity claim. Microfibre shedding is addressed by none of…
- Material record
TENCEL™ Lyocell
The high solvent-recovery rate belongs to this branded process, not to lyocell generally; generic fibre from an uncertified mill may recover materially less. FSC covers pulp origin only, so a supplier answering…
