Experience enhanced comfort and control with our signature TUNEDFIT™ Dual Lacing System. Now with two cinch cords per shoe, you can adjust the fit around the forefoot and midfoot independently in seconds. Paired with a wide toe box, it lets your toes splay, flex, and power through the longest runs in the toughest terrain.
Crafted from a high-performance woven fabric and reinforced with aramid fibers that are five times stronger than steel, the T1’s upper is relentlessly durable. Its anti-siphon knit tongue repels water, ensuring a breathable, fast-drying design that thrives in the harshest conditions.
LightCELL™, our proprietary midsole, is turbocharged through supercritical foaming. LightCELL™ weighs just 50 percent of EVA while offering 45 percent greater energy return – it’s battle-tested by hundreds of ultrarunners for consistent responsiveness, mile after mile.
The T1’s outsole features a trio of Vibram® innovations: Megagrip rubber for tenacious traction in any condition, Litebase for 30 percent less weight without compromising performance, and Traction Lug micro-features for up to 25 percent more grip.
