norda 055 Trail Running Shoes - Ultra-Distance All-Mountain Performance

The norda 055 is built for the world's most demanding ultra-distance races across all terrains and conditions. Designed with events like UTMB and Hardrock 100 in mind, it brings together a seamless knit sock collar, bio-circular Bio-Dyneema® upper, pure Arnitel® TPEE midsole, and a bespoke Vibram® Megagrip Elite™ outsole into a shoe that combines race-day resilience with standout stability across every kind of mountain terrain.

Seamless Knit Sock Collar for Second-Skin Lockdown

The one-piece seamless knit collar is a first for norda footwear. Designed to deliver a second-skin fit with no hot spots or weak points, it works with the norda Fit Lock System and Dyneema® laces to keep trail debris out and the foot locked in place across technical terrain. The integrated construction increases both lockdown and comfort without adding bulk, making it particularly effective during ultra-distance efforts where foot security becomes critical over many hours.

Bio-Dyneema® Upper with Dyneema® Laces

The bio-circular woven Dyneema® upper, combined with nylon, is impossibly strong and featherlight. Its weave pattern allows maximum breathability and rapid water drainage, keeping feet comfortable across stream crossings, wet trails, and varied mountain conditions. The laces are also made with Dyneema® for four times the strength of standard laces, greater abrasion resistance, and improved stretch. Slimmed from 5mm to 4mm, they reduce weight without compromising durability.

Pure Arnitel® TPEE Midsole and eTPU Insole

The midsole is crafted from pure Arnitel® TPEE, delivering best-in-class resiliency ratings, exceptional responsiveness, and standout durability whilst remaining incredibly lightweight. Unlike blended foam formulations, the pure Arnitel® construction maintains stable mechanical properties across all conditions and climates, making it reliable from pre-dawn alpine starts to sun-baked afternoon descents. The eTPU insole adds maximum energy return and comfort underfoot.

Vibram® Megagrip Elite™ Outsole with Quebec Topography Linework

The proprietary norda x Vibram® Megagrip Elite™ outsole features 5mm lugs for superior grip across all terrain types. Rear and front lips increase durability in the highest wear zones, whilst 360-degree reflective linework inspired by the topography of Quebec adds visibility from all angles during low-light efforts. The design language nods to both the 001A and 005, maintaining visual continuity across the norda range.

Is the norda 055 Right for You?

The 055 is designed for runners who spend serious time in the mountains and need a shoe that holds up across the full duration of an ultra. The seamless knit collar solves one of trail running's persistent discomforts, keeping debris out and the foot secure without requiring a gaiter. The pure Arnitel® TPEE midsole maintains its properties regardless of temperature or conditions, which matters when a race spans an entire day and night across changing terrain. Vibram® Megagrip Elite™ with 5mm lugs handles the grip demands of technical trails whether wet or dry. Dyneema® laces and upper reduce weight without sacrificing strength. The Fit Lock System provides customisable lockdown for varying foot shapes and swelling across long efforts. If you're training for or racing events that demand sustained performance across technical mountain terrain, the 055 is built specifically for that challenge.
