The 055 Trail Running Shoe pairs a knit collar with norda's stabilizing Fit Lock System to create one integrated lockdown mechanism, eliminating hot spots and debris ingress that cost time and focus at race pace. The Arnitel TPEE midsole returns energy more consistently than foam alternatives across temperature swings, so the shoe performs the same on a cold alpine start as it does on a sun-baked midday climb. The Vibram Megagrip Elite outsole adds front and rear lip geometry for durability on abrasive terrain, and the 4mm Dyneema laces hold structural integrity across the full distance without adding weight. What Our Gearhead(R) Experts Are Saying:"The knit collar seals out grit on loose, dusty descents the way a gaiter would, but without the bulk. My feet stay locked in place even when the trail turns to scree."
