Learn more about stack heights and how we measure them.-
Minimal

Product Highlights:
The Altra Olympus 275 HiLo trail running shoe is a max-cushioned cruiser, made for technical terrain and plenty of daily training miles. It's built to carry you comfortably across high ridges and low basins as you endure the mental highs and lows through days and nights of weekly miles and ultras. Maybe even a certain high-elevation, lonely 100-miler in Colorado, wink wink.
While premium and protective EGO MAX foam has been an Altra staple in other models, this marks its first-ever appearance in the Olympus family. Significantly lighter and slightly softer than the previous CMEVA foam, it's primed to take care of your feet and legs better than ever, delaying the discomfort and fatigue we know are always coming.
Continuing the upgrades, the Vibram Megagrip outsole now covers even more area for greater grip and durability. New to the HiLo, the larger lug shapes now feature Traction Lug details for even greater peace of mind on wet rocks and gnarly sections of trail.
Lastly, wrapping your foot with top-performing durability and abrasion resistance, the one-piece Matryx upper creates a relaxing environment that feels comfortable, protective, and breathable.
At the end of the day, or the dawn of a new one, the Altra Olympus 275 HiLo provides an incredible combination of long-haul comfort, toughness, and capability. It's a movable home for your feet, carrying you confidently over (or through!) anything your adventure has in store for you.
