These are the Swiss-engineered men’s walking shoes with a patented multi-layered curved sole that helps relieve back pain. Recommended by physical therapists and chiropractors, the shoes’ physiologically friendly polyurethane midsole promotes a rolling gait that mimics walking barefoot on soft, uneven surfaces such as springy moss or a sandy beach. This motion actively engages the supporting muscles of the lower body, improves posture, increases circulation, and encourages a soft heel landing that lessens strain on the back. The synthetic leather and mesh uppers offer a stellar combination of durability and breathability, while the outsole is made from abrasion-resistant rubber that provides confident traction on most any terrain. Gray. Sizes 8, 9, 10, 11 and 12. (1 lb.)
