The Altra Olympus 275 HiLo is a lighter version of the popular Olympus 275 trail running shoe. After 200 miles, the runner finds the weight reduction significant, especially for long runs and ultras.

The HiLo uses Altra's EGO MAX foam, which is 15% lighter and 10% softer than the EVA foam in the original. Despite the changes, the cushioning and fit remain consistent with the original model. Read more travel coverage.

The shoe's grip has improved with Vibram Megagrip and Traction Lug, providing better traction on various terrains. The runner appreciates the lighter feel but notes that the taller stack height may not suit all types of trails. Related: Catamount Falls via Thomas Trail: A Mixed Terrain Run.
