Running Lite-Mesh No Show Socks are a low density protective padded sock. We use dense padding, as opposed to thick padding, as it protects feet without adversely affecting the fit of the shoes. Our Running Lite-Mesh Socks were designed to be used in mild to warm conditions, keeping feet cool, dry, comfortable and odor free. Breathable mesh cools and dries feet. Flat toe seam. Anti-slip wedge helps prevent sock from slipping down into shoe. Y-heel improves fit.
