I have been wearing Heat Holder socks for around 4 years and rotate through 8 pairs during colder months. I replace every 15-18 months or so. The most recent batch are visibly of lower quality than those I have purchased before and they are deteriorating at a much quicker rate. Quality has reduced but pricing I increased. I would look for an alternative product next time.
Brilliant socks, excellent quality , fleece lined , better than wearing slippers
The warmest socks I have worn, wish I had a pair during my skiing days (now long passed).
Husband says they keep his feet toasty warm, had thermal socks before and they take ages to dry but these don’t take to long at all
