These Ladies Ultra Lite Socks in Black are specially designed to fit comfortably inside tighter-fitting and formal shoes. With an amazing 1.0 TOG rating, these 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.

Keep my grans feet lovely and warm
Disappointed that after taking the Ultra Lites off for the first time only a couple of hours I noticed there was fluffy lining coming loose and the elastic top had unravelled. Won't stop me buying Heat Holders but would sadly not get these particular ones again
We are sorry to hear of the issue, our customer service team shall send you a private message to resolve.
It's tight on the legs (I'm skinny), AND GOT HOLES AFTER THE SECOND USE!
