Dynamic fit is the new AKU technology that dynamically adapts the boot’s heel tension with your natural stride to increase comfort and stability.
PROPULSION
When stepping forward, pressure is applied to a set of laces connected to the free-floating webbing located behind your heel (1). The heel counter pulls forward, locks your heel into place and reduces your heel slip (2).
LANDING
Landing on your heel releases pressure on the laces and relaxes the boot’s heel webbing (3). This movement allows the boot’s heel counter to bend backwards together with your achille’s tendon and to reduce pressure on your legs (4).
