The TKX boasts effective moisture-wicking, while added cushioned instep and arch ensure more comfortable wear. The TKX's low-profile toe seam won't dig or rub, and added vent panels mean your foot will not overheat. The TKX Unisex Trekking sock is proudly made in the USA.

Thorlos TKX are the best!

Thorlos TKX socks are the best! Buy boots/shoes half size larger for these TKX. They have great bottom thickness that works for my feet pads. TKX Throlos last and last. They protect out feet very well. Feet breathe. Thorlos know how to research feet problems before they make socks with their own fibers!
