Moisture is your foot's worst enemy. Moisture causes blisters, discomfort and athlete's foot and it allows odor-causing bacteria to flourish. However, you also know your feet are going to get wet, either from sweating, stepping in a puddle, running across wet grass, or getting caught in the rain. These new Physical Training Socks are designed with a special Dual Layer Moisture Removal System that moves moisture off the skin, through the inner Drymax layer and to the outer absorbent layer almost instantly. Our Physical Training Socks are a medium density protective padded sock. We use dense padding, as opposed to thick padding, because it protects feet without adversely affecting the fit of the shoes. Our sport socks are designed to be used in cool to warm conditions, keeping your feet dry, comfortable and odor-free. Material: Drymax / nylon.
