FITS Thick Socks FITS Socks Size: M (24.5-26.5cm) Used only 3 times for snow mountain climbing. Since they were used with new winter boots, I think there is little odor transfer. Although used only 3 times, there is some pilling due to washing because they are wool. Please refrain from purchasing if you are concerned. (Wool can pill even after one wash) For those looking for a relatively beautiful item, or those who want to try FITS socks for winter, how about it? Thick socks that are strong, using 23μm wool. The back side is pile-knitted, providing the most cushioning and heat retention, and are less likely to cause blisters. They go well with hard mountaineering boots and are recommended for winter mountaineering. Of course, they are also recommended for everyday wear in the cold season. Made in U.S.A
