The original women's, men's (unsiex) running shoes Puma evoSpeed NetFit Sprint were designed for short distance runs. 100m-400m sprint and hurdles. Thanks to the use of the unique NetFit system with the ability to adjust the lacing spacing, it is possible to adjust the shoes to both wider and narrower feet. In addition, the shoes come with a set of spikes and a special key for unscrewing and screwing them on.The sole of the shoe was designed for running, so it is stiffened to reduce energy loss when bouncing off the ground. In addition, in the front part of the sole, in addition to the spikes themselves, there are also hard plastic protrusions that additionally increase grip. The whole is complemented by a special sock surrounding the foot ensuring high comfort of use and a foam insole with shock-absorbing properties.The outer material of the shoes is made of the highest quality textile material. The inner upper of the shoe is lined with a soft textile material ensuring maximum comfort for the foot. The sole of the shoe is made of high-quality, hard and abrasion-resistant synthetic material and is based on a unique structure of a stiffened platform with protrusions and a combination of eight replaceable spikes strategically placed.
