Terrex Agravic Speed Ultra Trail Running Shoes

Designed for speed and endurance on demanding trails, the Women’s adidas Terrex Agravic Speed Ultra Trail Running Shoes are engineered to push the pace during ultramarathons and rugged trail races[1][6]. The shoe combines race-winning technology and outdoor expertise, featuring a breathable, foot-hugging synthetic upper reinforced with abrasion-resistant seamless overlays for durability[1]. A gusseted tongue helps seal out debris, while lace closures ensure a secure fit[1]. The textile lining uses recycled PET, aligning with eco-friendly practices[1].

At the core is the Lightstrike Pro midsole, offering maximum cushioning and a responsive, ultra-bouncy ride—ideal for long distances and technical terrain[1][7]. Full-length Energy Rods embedded in the midsole provide tuned stiffness and propulsion, mimicking the natural bones of the foot for efficient energy return[1][7]. The banana-shaped rocker geometry promotes a smooth, fast roll-off, enhancing turnover and comfort over extended runs[5].

The outsole is made with Continental™ rubber, known for superior grip in both wet and dry conditions, while 3 mm lugs tackle varied surfaces without excessive weight[1][5]. The heel-to-toe drop is 8 mm, with a 38 mm heel stack and 30 mm forefoot stack, balancing cushion and ground feel[1][7]. The shoe is impressively lightweight for a trail shoe—approximately 7.8–8.1 oz per shoe in women’s sizes, depending on the source—without compromising on stack height or protection[3][5][7]. However, comfort in the upper is minimalistic, with near-translucent mesh for airflow and only thin foam strips in the heel for padding[3]. This design prioritizes breathability and weight savings, making it especially suited for hot, long-distance races where heat dissipation is critical[3].

Most suited for competitive trail runners seeking a lightweight, responsive shoe for ultra-distance racing, uptempo training, and technical trail running[1][6][7]. The Agravic Speed Ultra excels on moderately technical to smooth trails and is ideal for runners who value speed, efficiency, and a lively ride over maximal comfort or extreme ruggedness[2][7]. It is less recommended for highly technical, rocky terrain where more protection and cushioning might be preferred[7].
