What is the material of otz insole?

OTZ's insole is developed by using healthy wooden mat brands Corkfit and Corklite in cooperation with the customer research center of Stanford University in the United States. Made of pine and suede, it is soft and comfortable and has massage function.

The organic cork sole is made of TPU material, which makes the original hard outsole soft and more suitable for daily wear.

The whole shoe is made of natural materials such as suede, tanned leather and flax from Italy, instead of glue, so it is more comfortable to wear barefoot.
