Hiker Midweight Micro Crew Sock

The guarantee is why people end up owning six pairs: wear a hole in these and Darn Tough replaces them, indefinitely, without a receipt. The knit is dense enough that holes take a long time to appear, the seamless toe does not rub, and the merino blend stays wearable for days between washes. For most backpackers this is genuinely a buy-once sock. The midweight cushion is the limitation. It is too warm for desert and hot-weather hiking, and the dense pile holds water, so a deep ford means most of a day in damp socks where a thin synthetic dries in an hour. That cushion also takes up volume, so if your shoes are already snug, going midweight can effectively cost you a half size. At premium per-pair pricing, outfitting for a thru-hike is a real expense, and the warranty covers holes rather than the thinning and stretching that shows up first.
