Designed to provide a close touch on the ball and reduce the overall weight of the boot, the next generation PUMA evoSPEED 17.SL features a super-thin textile upper, while a patterned laser-cut SPEEDFRAME structure harnesses the foot when performing sharp turns. An external heel counter provides optimal fit and support around the ankle.The dual density nylon outsole of the 17.SL features raised SPEEDTRACK spines for torsional stability, allowing you to enhance your power when striking the ball or sprinting off the mark to evade opponents. Designed for use on firm ground, the soleplate of this boot features a mixture of conical and bladed studs to deliver superior grip and traction.PLEASE NOTE: The evoSPEED SL is not for training days. It's for your best days. Your match days. It may only be used on real grass and in fair weather conditions. A non-compromise lightweight proposition, this product is about speed, not endurance. But the moments it creates will last forever.
