These Mens Ultra Lite Swallow Micro Socks in Navy are specially designed to fit comfortably inside tighter-fitting and formal shoes. With an amazing 1.0 TOG rating, these men's thermal socks are three times warmer than a basic cotton sock, so you get more of our famous thermal protection with less of the bulk.
Formal and tighter-fitting shoes can often feel cold to wear. Not only do they offer less insulation than casual shoes, but most of the socks that will fit inside them provide little or no thermal protection.
