Altra goes all in with the Olympus 275 suited to a wide range of trail running. 

It's made from a one-piece MATRYX® woven upper that's both lightweight and protective which makes it an eligible candidate for high performance treks. A megagrip outsole is designed to help with traction in varied conditions, wet or dry it can do both. 

The compression moulded midsole is stacked with 33mm of foam under-foot, but still maintains the zero-drop ethos Altra is known for. The upper is constructed on the Original Footshape™ fit, providing maximum toe box room for your battered toes.
