The Flex Pro is built for riders who push it. Triple-density GripFlex footbeds absorb and disperse impact after hard landings, while dual-density heel pads protect where it matters most. A contoured anatomical footbed, ramped chassis, and outer-angled heel inserts lock your foot in and protect your knees on loading. Internal strap stiffening makes entry faster and keeps you locked in when you're pushing limits. KnitFlex seamless lining delivers a clean, no-rub fit. Four sizes — S, M, L, XL — for a personalised fit. Compatible with all North FlipTech and standard TwinTip boards. Compatible with all North FlipTech and standard TwinTip boards.
