Now available is the GT-2000 8 in performance knit. Everything else remains the same. Last fall's update offered a few tweaks to improve flexibility and shock absorption. An improved GEL provided better impact protection in version 8 of Asics’ everyday stability trainer and an even springier formulation of Asics’ lightweight FLYTEFOAM provided even better energy return. The forefoot flexibility of the updated GT-2000 was much improved, while the TRUSSTIC SYSTEM continued to provide solid and sure stability. If you liked the previous version of the GT-2000, this one is even better. If you have never tried the GT-2000 8, the performance knit version moves with the foot very well and is worth checking out.
