WHAT DOES IT DO ?
Bio-Stride is a patented two-piece hinging tongue assembly that permits the tongue to follow the movement of the leg throughout its glide/stride/walking range of motion, either forwards or backwards.
HOW DOES IT FUNCTION ?
When the WALK mechanism is open, the tongue hinges backwards to enhance walkability and gliding, by facilitating a longer fore/aft range of cuff movement. When flexed forward, the two tongue pieces lock together to function as a solid, one-piece tongue. A new, second hinge point - above the instep – extends flex range and facilitates more natural forward movement during steep climbs.
WHAT IS IT ?
External shell tongue which is constructed from resilient and responsive polyamide nylon plastic.
