To pack in the comfort without restricting our boot fit, we pull on icebreaker's Merino Ski+ Ultralight OTC Sock. Minimal cushioning has this pair fitting like a second skin, while the merino wool fibers help manage sweat to keep our feet feeling just right on long days. And with the Achilles support and comfort cuff keeping the fit secure, we don't have to worry about this pair slipping and bunching on us.
