The full-length midsole offers protection for the multi-lap races, while working well with the resilient surface of synthetic tracks. The spike plate extends from the toe into the arch, stiffening the forefoot, with a 4 spike configuration for efficient grip of the track. The heel and forefoot also feature a TPU sharkskin layer interspersed by toughened foam, light and durable in the process. The secure fit, efficient though minimal plate, and very light feel make the Wire 4 a distance spike worth serious consideration.
