The MBT Shuguli Gtx Shoes offers a Gore-Tex membrane which is completely waterproof for keeping your feet dry in all conditions. The shank, PU midsole with Pivot and the Masai Sensor create a soft surface that is akin to walking barefoot on springy moss or on a sandy beach. This MBT Shoes creates a natural instability underfoot, which activates the supporting muscle system and has positive effects on the entire body.
