The 2023 Flex LX have a sense of luxury that speaks the perfect balance between performance and design - North prioritized your comfort and fit above all else. Carefully designed to help absorb and disperse impact after gravity-defying boosts, the triple-density dynamic support technology provides effective shock absorption, while soft and springy GripFlex cushioning protects your heels and makes for softer landings. North added structure and stability, combining the triple-density dynamic support system inside the heel with a more contoured footbed and ramped chassis for increased lateral support. This ensures your foot rolls properly, providing a stable landing and protecting your knees and ankles when loading up to release into the air. To get the right fit, check that there's enough room for your toes to stretch and flex, and make sure the top strap doesn't slip or rub. The upper should feel secure, but not too tight, and the footbed should match the shape of your foot. Compatible with new FlipTech centreline TwinTip strap insert mounting pattern and offline inserts. Now available in 4 different sizes.
