T1 Trail Running Shoes – TunedFit™ Precision, Lightweight Power & Rugged Durability
Conquer tough terrain with the T1 trail running shoes, built for endurance athletes who demand precision fit, durable materials, and maximum performance. Featuring our signature TUNEDFIT™ Dual Lacing System, you can fine-tune tension at the forefoot and midfoot independently—perfect for dialing in the ideal fit on the move. Paired with a wide toe box, this design allows for natural toe splay and full-foot engagement on long-distance runs.
Engineered for extreme durability, the T1’s high-performance woven upper is reinforced with aramid fibers—5x stronger than steel—making it one of the toughest trail shoes available. The anti-siphon knit tongue repels water while maintaining breathability and quick-dry performance in wet, muddy, or humid conditions.
At the core, our proprietary LightCELL™ midsole leverages supercritical foam technology to deliver 50% less weight than EVA and 45% more energy return, offering long-lasting rebound and cushioning that ultrarunners trust over any distance.
For unbeatable grip and agility, the Vibram® outsole combines three innovations:
-
Megagrip rubber for unmatched traction in wet or dry conditions
-
Litebase technology to reduce outsole weight by 30%
-
Traction Lug micro-patterns for up to 25% more grip on uneven or technical terrain
