MBT® is the first physiological footwear that has a positive effect on the whole body. The work day will never get you down while wearing the Kabisa from MBT®. Leather upper with unique stitch detail on a lace-up oxford silhouette. Antimicrobial Dry&Cool mesh and foam sock lining allows for breathability and assists moisture management. Perforated EVA insole provides added cushioning with antibacterial treatment to reduce odor. Dual-board 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®) 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. Weight: 16 oz Product measurements were taken using size 41 (US Men"s 8).
