Norda 055 | Strato

At the vanishing point of distance, speed means freedom of the soul.

Sublime speed meets standout stability on the norda® 055, the ultimate all-mountain shoe. Featuring an integrated sock collar that prevents dirt and debris entry while enhancing lockdown and comfort, a light, durable Bio-Dyneema® Upper, an Arnitel® TPEE midsole with best-in-class energy return, and a bespoke outsole made with Vibram® Megagrip Elite, the 055 was designed for ultra-distance efforts across all terrains and conditions — like UTMB and the Hardrock 100.

The norda 055 combines race day grade resilience and responsiveness with a build that’s designed to tackle the world’s most technical terrain. Its one-piece knit “sock” collar — a first for norda footwear — supplies a “second skin” fit to keep trail detritus out and the wearer’s foot locked in place, while a bespoke Arnitel® midsole ensures benchmark rebound and stable mechanical properties across all conditions and climates.
