Made with soft yet supportive foam, the minimal design makes these Nike® Calm 2.0 slides easy to style with or without socks. Their contoured design is made from a single piece of foam for a smooth, seamless feel, while the subtle texture pattern on the footbed adds grip even when wet. These slide sandals are made of an ethylene vinyl acetate (EVA) upper, a foam insole, and an ethylene vinyl acetate lining. The outer shell of these slippers is made from water-friendly foam that is easy to clean. These slip-on sandals are designed with a rubber outsole that gives you excellent traction even on slippery surfaces.
