I've tried 2 different Darn Tough socks, with mixed results.

The first socks (link below) are a light-weight cushioned hiker (size L), which were way too tight, such that the weave tore in multiple places and wore badly. I exchanged them for size XL, but these also tore and wore badly.

Darn Tough refunded me and I bought a mid-weight cushioned hiker (size L), which fit great, no problems and they seem to wear very well. I wonder why sizing is inconsistent for at least the 2 types I tried?
