Very well-made & warm. I expect them to last a few winters. They were a little snug, but I expected them to be that way since they are sized up to 12.5 and I wear 13D shoe / 14 boot. I may pick up a few more pair.
Outstanding value on these sox
Review byMike Verified Buyer
My foot runs on the small side (between an 8.5 and 9) no problem on fit. Easily worn over a sock liner and kept my feet warm and toasty on an all day winter trout fishing trip in knee deep snow.
100% Recommend for anyone looking for some warm socks at an outstanding value. Made in USA too!

Serious winter socks. Thick. Got them for Micky mouse boots
An excellent value
Review byRIC Verified Buyer
Always on the lookout for a good pair of 4-season hiking socks, and these ones are a serious qualifier. Although they seemed to run a little too small (I wear a US 10.5 boot) to wear over an inner sock, their quality and durability can be felt immediately. Not too thick to be constricting under a trail boot yet remarkably soft and with perfect thermal insulation. I have not worn them enough to really assess their durability but at their price I feel completely satifsfied with the purchase.

Same socks I wore with my flight boots when I served. Nice cushion in the heel and toe and not too tight on the calf but they do not slide down either. Price is great, about a third or less than any place on the web. I will order a few more pair before they are gone. Thanks, KS for a great deal!
