Darn Tough took their original Stride and went back to the drawing board — stripping it down, rebuilding the fit and coming out the other side with one of the lightest, smoothest men's running socks they've ever made. Performance arch support helps reduce fatigue on longer efforts, flex windows eliminate bunching, and targeted reinforcement sits exactly where you need durability most. The result is a sock that practically disappears once you lace up, leaving you to focus on the road or trail ahead. Ultra-lightweight merino wool wicks moisture away and keeps things fresh, while the no-cushion profile gives you that direct, ground-feel connection that faster runners tend to prefer. The micro crew height adds a bit of coverage above your trainers without any extra bulk. Guaranteed for life, because Darn Tough are confident you won't wear them out — though you're welcome to try.

| S | 5.5-7.5 | 38-40.5 | 5-7 |
