        The engineering behind ACL / MCL-Friendly Howell SkiBindings is actually simple (1).

        During ‘slip-and-catch’ events that are the primary cause of skiing ACL and MCL ruptures — the center of the key component of the injury-producing forces enters the ski, laterally, immediately behind the projected-axis of the tibia.  This special location where the center of the key slip-and-catch forces enter the ski is NOT sensed by ordinary 2-mode alpine ski bindings (NOT also by turntable-pivot bindings — no boot can release through the side-lugs of a pivot-turntable;  NOT by ‘diagonal heel release’):  there’s no possibility of release, no matter the setting.  But this same specially-located slip-and-catch force produces a large abduction-moment centered within the ACL and MCL.  

        Pop — a $20,000-to-$50,000 injury that typically requires ACL replacement surgery;  8 to 10 months of aggressive physical rehab;  lifetime osteoarthritis starting 5 years after injury.  Even highly rehab’d World Cup ski racers never return to full athletic performance.  On top of the severity — MCL and ACL injuries are the most frequent injury in skiing — and women incur 3-times more than men.

        ☀️ However, a binding with ADDITIONAL lateral-heel release can respond to the unique position of slip-and-catch forces IF properly tuned and IF the special lateral-heel release mechanism is compatible with the non-standardized geometry of the heel of the boot.  


        HOWEVER — A BIG HOWEVER — a specially-tuned, properly-configured lateral-heel release mechanism that provides ACL and MCL friendly skiing MUST also NOT pre-release.  Howell SkiBindings uniquely provide key know-how and key intellectual property to block pre-release without high settings in all 3-modes of release (2).  Anti-pre-release is uniquely and decisively provided through Functional Decoupling between each of the 3-modes of release — plus Functional Decoupling between the other key structural-functions of ski-bindings — maximal edge-control and indifference to ski-flex.  Other bindings don’t have Functional Decoupling because Howell-patents block them.

        Double ahhhhh — an $800 investment in Howell SkiBindings provides all skiers with healthy, friendly skiing — though 100% prevention is impossible.  ( $80 pre-order, 30%-off net upon shipment Oct 2023 )
