Built for the water ahead
Flex PRO 2025
The Flex PRO is North's top-loading twin-tip binding: drop your foot in, pull the strap down and go. KnitFlex lines the strap seam-free and follows the shape of your foot, GripFlex rubberised EVA keeps you locked in once everything is wet, and triple-density pads under the heel take the sting out of hard landings. The contoured footbed sits on a ramped chassis for lateral support and knee alignment.

Technology
What makes it work.

New Internal stiffening
New skeletal stiffening inside the top strap improves the strap’s shape hold, making it easier and faster to slide your foot in and out and increasing support for your foot.

Adjustable top-loading strap
For quick setup and a perfect fit for all sizes. Strap Adjusters allow comfortable foot positioning, a secure feel and use of the toe bar. Simply drop the inner and outer Strap Adjusters into the baseplate from the top.

KnitFlex seamless topside comfort
Lightweight and responsive. The KnitFlex fabric is pre-tensioned and laminated to the foam inner, creating a 3D-curve without any creasing or stitching, that conforms to your foot shape.

Injection Velcro reduces water lift
Injection Velcro decreases sand retention, extended top flaps strengthen hold and reduce water lift. The split inner-velcro design ensures a custom fit on top of the feet with flexible hold.

Maximum Shock Absorption
Triple-density dynamic support absorbs and disperses impact. Softer, high-density impact pads protect the heel and are dual-moulded with a medium-density layer for serious impact protection.

Locked-in hold and grip when wet.
GripFlex lightweight, rubberized EVA provides soft cushioning and maintains grip underfoot when wet, while the fine grip pattern helps keep your foot locked in on various angles.

Anatomical support, structure and stability
Contoured, anatomical footbed and ramped chassis increase lateral support, structure and stability. The footpad is ergonomically angled for optimised weight distribution and knee alignment.

Ramped toe bar
An angled tactile edge prevents your foot from slipping during high rotation tricks. The toebar is a little lower on the Flex to provide a better fit for all different foot types.

Custom fit
In four sizes for a more personalised fit: S, M, L, XL. To ensure the right fit, check there's enough room for your toes to stretch and flex, and the adjustable top strap doesn't slip or rub.

Easy stance adjustment
Fasten in various positions, change your duck stance, move backwards (heelside) or forwards (toeside) or set a wide or narrow stance. We recommend starting with Setting II for 2023 boards on.
