The Radiantex and Felt Insoles is composed of three layers of space age technology: RadianTex™ on the exterior to reflect the cold, an open-cell foam in the middle layer to act as a reservoir and to lock in moisture, and a polypropylene inner lining to wick moisture away from the foot. Available in Adult sizes 7 to 14 in men’s sizing. For women’s sizes, we recommend to order two sizes down, if you wear a size 9 in US women’s, your best fit would be a size 7 US men’s. Adjustments can be made to the insole by easily be cutting down to size using a sharp knife and short, frequent strokes.
