Bests & Worsts Reviews from Amazon

People give negative reviews on an item like this because they do not know how to use or wear winter clothing. With socks it is very simple, a sock like this one will be fine in sub-zero weather if used correctly. You boot, shoe or whatever you wearing must be big enough to accommodate this or any heavy sock. If your boot or shoe is too tight or even just tight, YOUR FEET WILL BE COLD no matter what material the sock is made of. Air must circulate in your boot or shoe in order for your feet stay warm. The natural warmth given off by your foot will circulate inside the boot or shoe. If your foot is constricted by boots or shoes that are too small to accommodate heavy or multiple socks your feet will be cold. If wearing heavy thick socks or multiple socks ALWAYS buy boots at least a half size larger than you would normally wear. Sometimes you have to go a full size bigger depending on the boot or shoe. For even better results when wearing winter socks like this one, you should wear a sock liner under your winter socks. These are specially made to wear under heavy socks and are very thin and usually made of a polyester material to wick away any sweat from your feet. Most important though, is to have the right size boot or shoe, never wear boots or shoes too small to accommadate heavy winter socks. It's not the sock, it's the way you are using them.
