The Flex 4D boots are 15% lighter than other models, which makes them ultimately more responsive. During the testing phases of this model, Shane Bonifay and some other team riders who wanted a softer flex in a high-end boot were blown away by how maneuverable, yet secure this binding is on the board. Combining a welded, vented upper construction with a 3-in-1 closure system makes this binding one of the lightest and most adjustable in LF's lineup. The point of the 4D Chassis System is to make the ride more responsive since the board and binding can flex together. 45° angle adjustments beneath the rider's feet create better board response and flex within all directions. Honeycomb FlexFloor absorbs impact and reduces overall weight. Reflex liner wraps your ankle for a better fit and more supportive flex. The liner's tapered edges reduce bulk and eliminate air gaps for a snug fit.
4D Chassis Flex Track System: The smallest footprint in the industry! A smaller footprint allows the board to perform at its truest flex and gives the rider the maximum feeling of response.
Honeycomb FlexFloor: Absorbs impact, reduces the binding's weight, and provides performance-driven flex.
45° Angle Attachment: Attachment points underneath the rider's feet increase leverage for better board response and flex in all directions.
Articulating Upper Cuff: Featured on the pro models to allow maximum range of motion. The upper flexes independently like a hinge without material backing.
Reflex Liner: The Reflex features totally new tongue design that wraps your ankle for a better fit and more supportive flex. The liner tongue has tapered edges, reducing material overlap inside the binding. This feature reduces bulk and eliminates air gaps for a snug, full-contact fit. The notched top cuff improves your range of motion and has a better fit which reduces leg fatigue and removes pressure points. The Reflex also has a 3D molded Impact EVA bottom with 2.5° of cant, toe lift, a deep heel cup, and a supportive arch underneath your foot.
Dual Lace Zones: Allows lace tension to be different in the lower and upper zones so the rider can customize a secure and comfortable fit.
