The name says it all – these socks are Ultra Comfy. They are the perfect blend of wool and synthetics that balance the temperature of my foot from winter to summer. The socks are built with thinner tops and cushier bottoms that allow me to have enough room in my shoes to keep my feet from feeling cramped like other warm socks do. The best part? I love all the unique colors and designs that run from basic to cute to crazy that make me smile every time they peek out from under my pant leg.
