Our insoles come in two versions:
Wool insoles: Hand-washable. Treat them like a wool sweater: washable, but not too often, otherwise the structure may suffer.
How to clean wool insoles:
1) Gently apply mild detergent.
2) Rinse with lukewarm or cold water.
3) Air-dry.
TENCEL™ insoles: Wipe with a damp cloth or gently rinse with cold/lukewarm water. Do not soak excessively and do not machine wash.
