Review: Thin, protective sock - Good quality. My husband b and wears them under wool hiking socks. They keep his feet dry and prevent blisters.
Review: Warmer than other sock liners - For years I bought my sock liners at SportMart and then Sports Authority. They would only have one type available, either Fox River or a similar brand. They weren't the Therm-A-Wick model. I was just buying them to add an extra layer under my socks in cold weather to keep my feet warmer, which they did. I didn't know anything about the moisture-wicking that sock liners are supposed to do, and I can't speak to that because my feet don't sweat much in cold weather. I did like how easy it was to pull on my regular socks over the sock liners. My older Fox River liners never seem to wear out, but I occasionally lose them as I do laundry in a laundry room of my apartment building, so I have to replace them periodically. I tried one pair of silk sock liners from Lands End, and I didn't like them as much as I thought I would; the material was not as slippery and not as thin and so it is harder to pull my socks on over them; also they are wearing out much faster and getting close to developing holes in them. I can't seem to find sock liners in local sports stores that are as smooth as the Fox River ones I already owned, so I went online and found that Fox River has a model of liners that are specifically for cold weather! (I think the Fox River liners I already had were made more for heavy exercise in warm weather, to help with sweating). So I bought a pair of these Therm-A-Wick socks and they really do keep my feet a little bit warmer than my other Fox River liners, and are nearly as smooth and thin as well, so still easy to get my socks over them. I just bought a second pair! They only come in white, I would love to have some in black, but that's not really a big deal for me. I would not wear these Therm-A-Wick sock liners under regular socks in warm weather, in fact I don't wear any sock liners in temperatures above 50 degrees Fahrenheit; my feet would be too warm. I never wear these on their own, only under other socks.

### ⭐⭐⭐⭐ Run smaller length wise than standard socks
*by M***E on October 23, 2023*

These socks fit tight which is fine but I wasn't used to a sock coming about 3 inches above the ankle. I called and they told me this was standard for a crew sock to come about 4" above the ankle. They did work as described under heavier socks but did not test them over a long term. They seem to be well made and I have tried nylon socks but they did not work well. I have a wide foot and they thought that was the reason for them not coming slightly higher over the ankle.
