Get it and go with the PUMA Ultra 5. The catalyst for generating maximum energy return for instant acceleration is the SPEEDSYSTEM outsole, a proprietary design from PUMA that blends high-performance fiber base material with an external heel counter and an evolutionary stud system. FastTrax stud design implements research-based insights to provide more traction for the game's key moments: accelerating, cutting at the drop of a dime, and breaking with instant deceleration. A PWRTAPE SQD support frame stabilizes the foot inside the cleat -- without hindering agility and freedom of movement. Savor the game with better lockdown thanks to a lightweight (and removable) sockliner with Nano Grip technology, along with the Ortholite heel cushion.
