The BLAST FF™ 3 model is designed to provide advanced stability for athletes performing dynamic movements on offense and defense. ? By revamping the upper's forefoot design, we were able to make this shoe more flexible for multi-directional movements. ? Our designers also added a MONO-SOCK™ construction for a better hold around the ankle. Lastly, the TURNTRUSS™ component in the rear lateral section of the outsole facilitates smoother transitions between each stride.
