Comfort. Performance. We built it for both. The new VIA Olympus 2 features a softer Altra EGO™ MAX midsole foam, with the same generous stack height but light, luxurious (and squishier) cushion. A plush footbed for an improved step-in feel. Get that “ahh” feeling as you lace up and let it follow you with every step. Rocker shape geometry encourages an efficient toe-off and a refined molded heel collar ensures a comfortable, secure fit. Room for your toes and zero drop create Altra’s natural fit, so you can move the way you were designed to. It’s a shoe made to go big on comfort, so you can go big on miles.
