Description and parameters

New strap construction, proven sole composition. The Performance Z-tech leather is a classic-style versatile sandal with toe loop lacing and a natural leather insole.

The advantages of a leather insole are clear! It is pleasant, natural, and absorbs sweat*— a clear choice for many. However, it’s not ideal for dirt, moisture, and mud. In such environments, a synthetic insole found in other models will perform better and suffer less wear. But if you mostly move around clean and dry environments like cities or indoor spaces, the leather insole will be a more comfortable and functional option.
