Pssst...wanna know a secret? Our shoes are made with something super cool: removable antibacterial chrome free leather insoles! Plus, we've got an extra removable insole, just in case. And get this - the leather for our uppers and linings comes from certified suppliers. How's that for sustainability? And hey, check out our composition: Upper Material - Leather, Lining and Insole - Leather, Sole - Thermo Rubber. Boom!
