Great trail running shoe

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: 45

I've been running in Rocky Mountain National Park all summer in these and they are perfect. Tons of grip to keep you on track in technical trails. And they have held up great.

They are consistent with Scarpa sizing, I'm a 45 in boots and running shoes. So maybe go up a half size if you have not purchased Scarpa before.
