If you come from a heritage of softer socks and want the same feel as you go sockless, these are your FLAT SOCKS. These Light Heather Grey FLAT SOCKS are the real deal. They feel as good as they look; soft, cozy, cushy, giving a much more natural feel underfoot. Get the feel of a soft wool sock while freeing your feet and going sock-free. Sizing: These socks are trim-to-fit. The Small size fits up to women's size 11 (or men's size 10). If possible, remove the shoe’s insole and use it as a guide for trimming your FLAT SOCKS. Replace shoe insole when finished. If your shoe’s insole is glued in or difficult to remove, use trim guides stamped into the underside of FLAT SOCKS to trim to the right size.
