A snowboard boot and binding system is disclosed which facilitates the engagement and disengagement of a snowboard boot and binding. The snowboard boot may include a boot engagement member extending from a rear of the boot. The boot engagement member is moved downwardly into a corresponding binding engagement member to provide an arrangement which prevents forward movement of the boot. The boot engagement member also may include one or more serrations to engage with one or more pawls on the binding to prevent upward movement of the boot. A snap-in arrangement may be provided in a boot toe region. The boot has protrusions extending outwardly from each side of the boot to engage with catches on the binding sidewalls. As the boot is pressed downwardly into the binding, the protrusions splay the catches until reaching recesses, at which point the catches rebound to capture the protrusions against upward movement.

A sport board binding system includes a receiver configured to be secured to a deck of a sport board, a boot, and an intermediate locking member. The receiver defines a channel extending inward from a periphery of the receiver. The boot is configured to be worn by a user and includes an engagement mechanism. The intermediate locking member includes a lower head connected to an upper head by way of a neck with the lower head selectively housed within the channel of the receiver and the upper head selectively housed within the engagement mechanism of the boot.

Provided herein are various embodiments for a boot for releasable engagement with a binding having a downwardly facing ledge and a toe strap. The boot preferably contains a sole, a toe portion, and a heel portion. The boot preferably also contains a heel retaining device extending rearwardly from the heel portion of the boot and having an upwardly facing engagement surface at the top of the device which engages with the downwardly facing ledge of the binding to prevent vertical movement of the boot relative to the binding while allowing forward horizontal movement of the boot relative to the binding.

The present invention contemplates a binding system for a snowboards and the like. The system includes a soft-soled boot having a hardened exterior shell consisting of a toe portion and a heel portion, which are linked by at least one sidewall portion. The toe and heel portions include two toe and two heel pegs respectively. The boot includes an instep portion having instep cables for adjusting the boot to the wearer and the cables are adjusted by grommets and tightened in position by at least one resting bar. The binding has a base plate for connecting to the snowboard. The base plate further supports a pair of toe hooks adapted to engage the toe pegs and a pair of heel peg levers adapted to releasably engage the heel pegs of the boot. A grappling hook and ratchet mechanism grabs the resting bar on the boot.
