Strap in and hold on with the Custom Adjust’Em ZX/2® Yampa. A new lighter-weight outsole keeps you quick on your toes with a 20% outsole reduction. With a net fit design, Chaco's are also reducing their impact on the environment as the outsole and midsole are adhered without any rubber waste. Your favorite sandal will save your foot, posture, and alignment with the ADDSTRIDE™ platform, while the net fit design keeps a few more scraps of rubber out of the landfills.
