Flex Pro Binding 2026Cushioning. Support. Shock absorption. The Flex Pro are engineered to help absorb and disperse impact after gravity defying boosts, with triple density dynamic support technology to protect your heels and guarantee softer landings. For 2025 weve updated the Flex Pro with a new internal skeletal stiffening inside the top strap. This stiffening wing improves the shape hold of the top strap, making it easier, and faster, to slide your foot in and out.
