The Mephisto Rufo Sneaker combines fashion and function. Innovative SOFT-AIR TECHNOLOGY is the secret behind Mephisto's extraordinary walking comfort. Shock is reduced to an absolute minimum with the flexible, permanently elastic and extremely soft SOFT-AIR midsole. It is like walking on a cloud, so you feel fit and full of energy even after long hours of wear. Along with an all-natural inner lining, SOFT-AIR TECHNOLOGY ensures a healthy and constantly pleasant foot climate. Special shock absorbers in the heel and the soft, shock absorbing SOFT-AIR midsole reduce stress on the joints, vertebrae and the spine from walking on hard surfaces.
