The recently arrived Rook Block Twist Crew Sock features the same warmth and comfort as the ORIGINAL™ Heat Holders® Crew sock, but with a striking and fashionable block twist design!

Keep feet warm on the coldest of days and pull on a pair of block twist style crew length Heat Holders® for men, the warmest thermal sock.

Thick, chunky and with a massive tog rating of 2.34, Heat Holders® are made from a specially developed heavy bulk yarn which has extreme thermal qualities. With long pile cushioning, these thermal socks will help keep feet fully comfortable and supported.

The inside of each sock has been intensively brushed such that they not only feel sensationally soft but also trap warm air close to the skin keeping your feet warmer for longer.

Heat Holders® are also non-binding and provide relief for cold feet due to circulation problems.
