The Wrapt lets your feet work the way they want to, without support or guidance in any direction. It's wise to start carefully when adopting barefoot footwear. As there's no significant support or cushion, and the drop is zero (meaning the heel and front are at the same height), your muscles and tendons have to get used to working in a different fashion. Allow your body to recover between exercises and notice your feet and legs gain strength! - Genuine leather as surface material - The lining is made of breathable mesh fabric - Weight only approx. 270 g / pc - Very thin midsole - Quantum Grip outsole - Heel and front stack 13 mm
