The PUMA evoPOWER Vigor 1 K Lth FG football boots are designed for use on firm ground.The evoPOWER Vigor is PUMA's most technical power offering to date, and brings you even closer to the ball for greater control when striking the ball. The one-way stretchable Adap-Lite upper support cage allows the foot to bend, mimicking barefoot kicking motion for increased power, while a K-leather enhances your accuracy and feel on the ball. The upper is applied with GripTex for consistent levels of grip on the ball in wet conditions, while a new slip-on stretchable sock construction enhances comfort and barefoot feel. Designed to provide superior support, the outsole is a result of studying how force travels through your stance and striking foot when connecting with the ball. As a result, the mix of bladed and conical shaped studs are strategically placed to ensure you can put more power into each strike while maintaining stability on firm ground. The spine of the outsole features a Gradual Stability Frame, which allows the outsole and upper to bend in harmony with the foot to boost your power.
