Most trail running socks are simply dark colored running socks with no specific “trail” features built-in. The Drymax Trail Running socks are the exception. TO help prevent dirt from getting inside Drymax Trail socks, there are no vents. In addition, the Trail socks’ double welted leg had extra padding around the ankle. This extra padding protects the leg and seals the top of the shoe to keep out dirt and debris. The Dual Layer Moisture Elimination System actually removes sweat, sweat vapors, and water from the skin through the inner Drymax layer to the outer absorbent layer. The double welt top is made of Drymax fibers to repel water, so when a runner splashes through a creek, the top of the sock stays dry. Drymax Trail Running Socks are a Medium Density protective padded sock. Dense padding used, as opposed to thick padding, as it protects feet without adversely affecting the fit of the shoes. The Trail Running Socks were designed for use to be used in cool to warm conditions, keeping feet dry, comfortable and odor free all day long. Also, the new 1/4 turndown leg gives you the choice of a 1/4 crew or mini crew leg Hecht and the choice of two colored logos.
