Hand-made, anatomically shaped footbed in vegetable-tanned calf leather. Provides optimal comfort and support with built-up arch, integrated pressure-relief pad and shock absorption at heel. With carbon filter for optimal hygiene. Slim shape that fits most shoes. The outer layer of the sole is made of soft, malleable, hardwearing calf leather of premium quality. Leather allows the feet to breathe. Vegetable tanning is environmentally friendlier than traditional chromium tanning. The thin, lightweight orthopaedic bridge supports the arch, improves posture and helps prevent heel spur. The integrated pressure pad relieves pressure and distributes muscle tension, while the concave heel and heel cushion have a protective, shock-absorbing effect. The active carbon filter in the sole keeps feet fresh by absorbing moisture and neutralising odours. Air the sole after use to prolong its lifespan.
