The Fox River Wick Dry Therm-A-Wick Ultra-Lightweight Crew Liner Sock was designed for one purpose: maximum warmth with zero added bulk. At 50% Thermolite EcoMade polyester, 49% nylon, and 1% spandex, the construction is engineered to be as thin as possible while still delivering real cold weather protection. Fox River's exclusive Wick Dry technology actively manages moisture, pulling sweat away from your skin before it can cool down and make your feet cold and clammy. Made in the USA since 1900, Fox River backs every pair with a 1-year manufacturing defect guarantee. 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. ## Features - 50% Polyester/49% Nylon/1% Spandex - Made in the USA and Imported - THERMOLITE WARMTH WITHOUT THE WEIGHT: Engineered with Thermolite EcoMade hollow core fibers that heat up fast and lock in warmth, these ultra-lightweight crew liner socks deliver serious cold weather performance without adding bulk, perfect for layering under wool socks, thermal socks, or winter boots. - STAY DRY ALL DAY WITH WICK DRY TECHNOLOGY: Fox River's exclusive Wick Dry system actively wicks moisture away from your skin, keeping feet dry and comfortable even during high-output winter activities.

I love those socks and have bought them for gotta be over 10 years. Often wear them around the house without shoes or slippers including on a tile floor and they last and last. **Q: Are these made in the USA or imported description says both** A: They are made in USA, Osaga Iowa. It also says it's made with US and imported yarns. **Q: What is the fiber composition?** A: I know they are not made of cotton. I believe they are made of nylon, but not sure. **Q: Good heat retention for elderly?** A: Liner socks are designed to wick away moisture and reduce friction between the shoe/boot and the outer sock. The best insulation heat retention will come from thermal socks, such as Heat Holders, also available on Amazon. Not a good choice if heat retention is your aim, great if you want liner socks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Thin, protective sock *by D***E on December 3, 2025* Good quality.

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. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/253675709-fox-river-therm-a-wick-ultra-lightweight-crew-liner-sock](https://www.desertcart.hr/products/253675709-fox-river-therm-a-wick-ultra-lightweight-crew-liner-sock) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-24*
