The soft microfiber top layer is what sold me — no hot spots even after a full day of hiking steep trails. Pressure relief on the downhills was noticeable right away, and they stayed put inside my boots.

Wore these in my hiking boots on a rocky trail and the arch support held up the whole way down. Only gripe is the edges felt a bit stiff the first couple of outings before they broke in.

Swapped these into my hiking boots before a weekend trip and the arch support made a real difference on the downhill sections. Only gripe is they took a day or two to break in and felt stiff at first.
