The Drymax Diabetic sock is designed so as not to reduce circulation or leave marks on the leg. It has a soft stretch leg, and the inside of the foot area is seamlessly smooth. The Diabetic Sock has our special Dual Layer Moisture Removal System. This system moves moisture off the skin through the inner Drymax layer to the outer layer almost instantly. Keeping the skin dry provides a more healthful environment for sensitive diabetic feet. Our Diabetic Sock is a Medium 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. The Diabetic Sock was designed for use in cool to warm conditions, keeping feet dry, comfortable and odor free all day long.
