What Handmade German Insoles is made of, ingredients and materials
Insoles combine natural leather (top layer), cork (midsole), and textile backing, which inherently avoid many synthetic polymer hazards. Leather and cork are minimally processed plant and animal materials with established long-term safety records in footwear. The textile component is typically cotton-polyester blend; low exposure risk since insoles sit inside shoes away from skin contact and are not heated during use.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Formaldehyde / VOCs
Cotton-polyester blends may be treated with formaldehyde-based dyes or finishes; The brand provides no material specification. Exposure is minimal (contact via foot sweat), but sensitive individuals may experience minor irritation over extended wear.
Source, ATSDR ↗Azo dyes in leather or textile
Leather tanning and textile dyeing sometimes use azo dyes; German manufacturing restricts banned azo compounds, but secondary amines and disperse dyes remain unregulated. No public testing of insoles exists; assume standard safety baseline for German-made leather goods.
Mold and microbial growth in cork
Cork is porous and absorbs foot moisture; insoles stored or worn in humid conditions may develop mold colonies, causing odor and potential respiratory irritation with prolonged exposure. Risk increases if insoles are not dried regularly.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leather degradation and breakdown products
Leather naturally ages and sheds; no toxic breakdown products are established for tanned leather in footwear insoles. Cracking and shedding are mechanical wear, not chemical hazards.
Heavy metals
German tanneries typically use chrome or vegetable tanning methods; both are regulated in the EU and the brand's sourcing is presumed compliant. No recalls or test data suggest contamination risk for this brand.

The brand's record and disclosure
The brand is a German family company with decades of market presence and no public safety recalls or regulatory actions on record. The brand does not explicitly market sustainability or chemical-free claims, nor does it publish detailed material sourcing or testing data. Absence of disclosure is typical for small heritage footwear brands but does not indicate hidden risk; German manufacturing standards generally enforce baseline safety for leather goods.
How it compares in its category
Insoles sit in the premium segment, natural material blends are chemically simpler than foam-only or gel insoles (which may leach plasticizers or degradation byproducts). They avoid the microplastic shedding risk of synthetic foam under foot pressure and heat. Cost trades off against budget insoles but aligns with mid-premium alternatives from Superfeet or Birkenstock, which use similar material logic.
If you buy it
Store in a cool, dry place to slow leather aging and prevent mold growth in cork layers. Replace every 12-18 months with heavy use, or when leather surface cracks or cork compresses noticeably. Hand wash only if soiled; do not machine wash or apply heat. Inspect periodically for mold or odor, especially in humid climates; if present, discard and air-dry shoes separately.
