Socks Review

These were a repeat purchase because they are very suitable for anyone who feels the cold. Unfortunately this time a hole in the toe appeared very quickly. Even so, I will still buy again.

Great winter warmers

I bought two pairs of these socks for my two brothers. They have both commented about how wonderfully warm these socks are. One of my brothers has blood circulation problems and suffers from cold feet. He has found that these socks keep his feet warm and comfortable.

Warm feet and legs!

Very impressed with my Heat Holders, my feet have been super warm whilst also keeping my legs warm. They are also soft and comfortable to wear.
