In addition, iWick® fibers are specially engineered to enhance breathabilty by allowing air to move through the fabric with ease. The result is that iWick® fibers do a superior job of keeping feet cool and dry.The Perfect Toe® The "Perfect Toe" is Feetures" trade-marked seam-free toe closure. The "Perfect Toe" is hand-linked so both the inside and outside surface of the sock are completely smooth, eliminating the irritation and discomfort caused by traditional toe seams. As a result, Feetures! socks provide protective comfort all day long.
