Olympus 6 vs Ultra Glide 3

The Altra Olympus 6 is a maximum cushioned trail running shoe built for going long and staying comfortable when the miles pile up. It pairs a deep, plush platform with Altra's signature zero drop geometry, so your heel and forefoot sit at the same height and your foot spreads naturally over rough ground. At 345g it is a substantial shoe, and you notice the weight on faster efforts, but that heft buys you real protection underfoot on rocky, root strewn trails. This is an ultra shoe first and foremost. It is happiest on all day adventures, long training loops and technical terrain where a wide, grippy outsole and a stack of soft foam keep your legs fresher for longer. If you want a lighter, nimbler trail tool the Altra Lone Peak 9 or the Hoka Speedgoat 7 make more sense. For runners who prize comfort and a natural foot position over speed, we rate the Olympus 6 highly.

The Salomon Ultra Glide 3 is a soft, high-cushion trail running shoe built for one thing: keeping you comfortable when the miles stack up. This is not a nimble mountain racer. It is a long-day cruiser for runners who want to switch off and let the shoe soak up the ground on runnable trails, canal paths and gentle single track. At 285g with a 6mm drop, it sits in that easygoing daily-trail zone, closer in spirit to a road-to-trail shoe than a technical fell weapon. The Contagrip outsole handles dry hardpack and light mud well, though it is not built for deep bog or scrambling. We rate it as one of the more forgiving ultra-distance trail shoes going, a shoe you reach for on tired legs and back-to-back weekends. If you want protection, softness and a relaxed ride over big distances, and you are not chasing course records on gnarly ground, the Ultra Glide 3 is an easy shoe to recommend.
