Our editor-in-chief swears by this hybrid sock for long days in his telemark boots. A blend of merino and polypropylene on the outside (for warmth) and polypro on the inner face (for blister prevention), the Fusion is like wearing a liner and sock in one.
After at least 50 washes, the material isn't as soft as most 100-percent merino socks would be, but the Fusions are holding their shape better than those. And he hasn't experienced a single hot spot while turning and touring. $16; wigwam.com
