NWOT - I tried these on for 5 min on the store treadmill. 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 underfoot feel. Step into 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. Weight: 9.6 oz / 272 g Midsole: Altra EGO™ MAX Outsole: Rubber Cushion: High Stack Height: 33 mm Drop: 0 mm Upper: Engineered mesh
