What Our Gearhead(R) Experts Are Saying:"The Spin Ultra 2 is everything I want in a long-distance trail shoe-light, cushioned, and super grippy. The new super critical foam feels springy but controlled, and the Vibram Megagrip outsole is confidence-inspiring on any terrain. It's my go-to for big training days and ultra races alike."When the miles stretch long and the terrain turns technical, the Spin Ultra 2 Running Shoe keeps us moving with ease and efficiency. Building on SCARPA's award-winning design, this updated version introduces a Super Critical TPEE midsole that delivers enduring cushioning, rebound, and energy return for high-mileage training or ultra-distance racing.

Designed for runners who chase vert, distance, and flow, the Spin Ultra 2 brings speed and stability together in perfect balance.
