The adidas Terrex Speed Ultra Trail delivers a performance silhouette created with direct feedback from Tom Evans, the professional long-distance trail runner who wore the shoe when he won the Tarawera Ultramarathon. A gradient black and grey finish is applied to the one-piece mesh upper, bolstered with no-sew overlays and accented with reflective three-stripes on the lateral side. A Lightstrike midsole in blue and Turbo red packs Boost cushioning in the heel for increased energy return. Underfoot, a lugged Continental Rubber outsole provides off-road traction.
