Ever tried exercising in a strait-jacket? No, that would be stupid and restrictive. Well so are big metal plates bolted to skis that are designed to flex. The Sync bindings feature Free Flex technology that has eradicated the restrictions traditional baseplates put on a ski. Each boot is set in a supportive yet flexible Exolast and is mounted with our Dual Plate design. The seamless outer shell and removable liner feature a dual lace system that pulls your foot back into the ergonomically shaped heel pocket. There has never been a better connection between you and your ski.
