The KIZIK® Siena Hands-Free is a retro-style sneaker with lightweight nylon with suede overlays that you put on without using your hands. An internal Cage™ flexes as you step in and springs back to hold your heel. A molded ethylene-vinyl acetate (EVA) foam midsole gives lightweight cushioning, and an Arch Form™ insole slowly molds to your foot for all-day support. A soft cotton lining keeps it breathable, and a padded comfort collar gives an easy, snug entry.
