The Adidas Arriba XJ Junior Running Spikes feature 8mm removable spikes for outstanding traction, and also helps to protect the foot over long distances, making this an ideal choice for runners of various disciplines. The pebax nylon plate is an exceptionally light outsole which offers a greater level of durability and performance, along with a distinct difference in energy retention with the material absorbing some of the energy in the footstrike for an added reactive spring in your step. Another addition to the Arriba is the SPRINTWEB upper material which consists of a lightweight forefoot construction fused to the mesh upper for a superb, weightless fit and feel, enhancing comfort and inherent performance. Other comfort features include an EVA insole and soft collar for premium ankle and underfoot cushioning and support.
