The MBT Tupu Shoes' leather/mesh upper is comfortable and durable. Hook and loop closure system for easy on-off access. TPU and glass fiber shank adds firmness to sole construction and also ensures a natural rolling movement of the foot with every step which optimizes the pressure distribution over the whole sole. PU midsole with pivot is the balancing section underneath the metatarsus which requires a active rolling movement with every step. Thus, activating a large number of stabilizing muscles throughout the whole body when walking or standing.
