Our Verdict
Altra’s Olympus 275 maintains the brand’s signature zero-drop platform and wide toe box, while introducing significant updates that enhance comfort, support, and upper performance. The new Matryx upper, reinforced with Kevlar, is lighter than the previous mesh, more resistant to abrasion, and remarkably breathable. It handles heat well and dries faster than any trail shoe I’ve tested, ensuring a comfortable and supportive experience.
Fit is snug through the midfoot and heel, with generous forefoot volume and a secure overall hold. The 33mm stack still provides plenty of cushion, but the ride feels more stable than earlier versions, especially on uneven or off-camber ground. Altra has removed the Achilles pillow from the heel, reducing bulk and resolving previous rubbing issues. Underfoot, the EVA midsole delivers consistent comfort with a slightly rockered feel over long distances.
The Olympus 275 offers reliable traction, thanks to the Vibram Megagrip outsole. The integrated scree sleeve adds effective debris protection without irritation. Stitching around the collar and toe has been reinforced, and overall construction feels more precise. For those wanting high cushion with dependable grip and standout breathability, the Olympus 275 is the most dialled-in version of the shoe to date, providing a secure and confident trail running experience.
