MBT - Gil Gil (Brown Nubuck) - Mens: You don t have to forfeit your summer fitness with the Gil Gil from MBT(R). Rich nubuck and mesh uppers feature huarache-inspired styling for breezy, warm weather wear. Adjustable instep and padded rear ankle strap allows for a customized fit. Microfiber lining helps wick away moisture for a healthier foot environment. Removable, perforated EVA insole provides added cushioning with antibacterial treatment to reduce odor. TPU and glass fiber shank adds firmness to sole construction and also ensures a natural rolling movement of the foot for even weight distribution. PU midsole with pivot is the balancing section underneath the metatarsus which requires an active rolling movement with every step. This activates a large number of stabilizing muscles throughout the whole body when walking or standing. Masai Sensor (Masai Barefoot Technology(R)) creates a pleasant feeling of walking on a sandy beach or soft moss. Instantly offers a natural instability to which the body automatically reacts increasing muscle activity. Durable rubber outsole offers lightweight support with good traction.
