Now, even the biggest swings stay grounded with POWERBAND 3.0. A re-engineered POWERBAND CHASSIS platform harnesses more of the swing's energy to deliver maximum power to the ball at impact. GRIPZONE's textured surface throughout the insole and extended into the heel locks the foot securely in place for more power and control. The addition of advanced THiNTech low-profile technology brings the golfer even closer to the ground for better stability, balance and footwork.
