Editorial take

Icebreaker's Ski+ Medium OTC socks are a reliable, mid-weight option for skiers and cold-weather hikers. The Merino blend, typical of Icebreaker, offers that familiar combination of warmth without bulk, good breathability, and natural odor resistance, which is a real plus on multi-day trips or when you're hitting the resort day after day. The over-the-calf height ensures they stay put and provide cushioning up past the boot line, preventing pressure points and rubbing from ski boots or high winter hiking boots.

Construction-wise, these socks feature targeted cushioning in the shin, heel, and Achilles, areas that take a beating inside ski boots. This strategic padding is noticeable without feeling overly plush or bulky, maintaining a good fit inside performance footwear. The instep and arch support are also well-executed, offering a snug feel that prevents shifting and bunching, which is crucial for blister prevention. While not the thinnest race sock, the medium density strikes a good balance for warmth and comfort across a range of temperatures, performing well in typical resort conditions down to moderately cold backcountry tours.

Durability is generally good with Icebreaker's Merino blends; these socks hold up to regular washing and wear, though high-friction areas will eventually show signs of use like any sock. Compared to synthetic alternatives, the Ski+ Medium OTC might be a bit pricier, but the natural odor control and superior thermoregulation make them a solid investment for anyone spending significant time in cold weather footwear. They're a dependable workhorse sock for active winter use, sitting comfortably as a go-to option that prioritizes comfort and performance over extreme minimalist profiles or maximalist warmth.
