As the name suggests, the Puma IGNITE Fasten8 Pro Golf Shoes feature Puma's Fasten8 PWRStrap Fit System. This all-new design consists of advanced webbing straps through which the shoe is laced. When the laces are tightened, the Fasten8 lacing system wraps around the foot to provide a secure, glove-like fit. The lightweight, strong PWRCAGE saddle integrates seamlessly with the webbing straps, keeping you stable and planted throughout your swing.
