DetailsVerified Customer Reviews for Zerofit Heatrub Ultimate Knee High Socks
 Warm when it cold yet comfortable when it gets war 
 26 Oct 2025 by Pat B 
I bought these for a trip to France at the end of September, knowing that I would have to leave in the early hours of the morning for a 2.5-hour ride down to Dover. Despite the overnight temperatures being chilly, 8-10 degrees C IIRC, my feet remained comfortable wearing breathable race boots. Once in France, the temperatures rose to the mid-teens, but I didn't feel too hot. They do an amazing job of keeping you warm whilst breathing well as temperatures rise, so you don't overheat when it gets moderately warm.
