The Terrex Agravic Ultra was designed in collaboration with one of the fastest trail runners in the world, Ekaterina Mityaeva. It is one of adidas' first trail running shoes with a sustainable TPE plate, made from 90% renewable carbon. This TPE construction runs the full length of the shoe, providing lightweight and durable protection from rocks on long-distance mountain trails. The Boost energy return technology and the incredibly lightweight Lightstrike technology ensure high responsiveness and shock absorption with every step, helping you maintain your pace on technical mountain trails.
