What Our Gearhead(R) Experts Are Saying: "I grab these when I want a running sock that disappears on foot but still gives me a little protection where it counts. The targeted cushioning takes the edge off repetitive impact, and the merino blend does a great job managing sweat and stink on high-mileage weeks. They're my pick for everything from treadmill tempo runs to hot road miles."We lean on the Smartwool Run Targeted Cushion Mid Crew Sock when we're stacking miles and chasing small gains that add up. The mid-crew height is a sweet spot for everyday running-enough coverage for dusty trails and breezy mornings, without feeling bulky in a lightweight trainer. And when the effort ramps up, the merino blend keeps things feeling breathable and comfortable, even when our pace (and body heat) climbs. Smartwool builds in targeted mesh and cushioning where our feet take the most abuse, giving us strategic comfort that helps reduce hot spots and fatigue over long runs. Merino wool's natural odor resistance keeps the sock feeling fresher between washes, while synthetic fibers boost durability and help manage moisture and temperature through changing conditions.
