GUC these have 41mi racing on them and a handful of training runs; under 70mi total with minimal wear to the lugs. Tons of life left so grab a deal on some highly versatile trail runners! Sizing: I’m a 7.5 in Nike/Saucony and 7 in these fits about the same. The toebox is fitted but the upper is stretchy so I found no blister issues even in the 4-6hr range.
