Howell SkiBindings arise from 5 decades of insider ski-binding industry experience by Rick Howell — co-developing worldwide #1-selling alpine ski-bindings for a major French company while in high school; high-level ski-racing; engineering thesis on ski-bindings at MIT (2); co-authoring the DIN-System; working 8-years as product manager at a major German ski-binding company; developing 5 worldwide #1 sports products; and conducting and presenting advanced biomechanical research on ACL-friendly skiing without pre-release (3). All of this know-how is parlayed into ACL-friendly Howell SkiBindings.
Howell SkiBindings provide a premium skiing experience.
Staying in the game is part of the deal. ACL-friendly Howell SkiBindings provide high-performance edge-control, maximum anti-pre-release, and ACL-friendly skiing to deliver the joy of alpine skiing, year after year.

Biomechanical Proof.
The biomechanics behind ACL-Friendly Howell SkiBindings and Howell-specified lateral-heel settings is actually quite simple.
During ‘Slip-Catch’ or ‘Phantom Foot’ events with shaped-skis, large abduction-moments are generated when the center of the forces that act between the snow and the ski, enter the ski, laterally, close-behind the projected-axis of the tibia.
Shaped-skis do not typically slip at one end — thus, rotation of the ski about the tibia-axis is minimal while lateral-loading is maximal. During this lateral action, the center of the abduction-forces that enters a shaped-ski is not sensed by ordinary 2-mode alpine ski bindings because the center-of-effort is located close to the tibia-axis and near the center of an ordinary binding’s axis of rotation: there is no effective lever-arm within an ordinary 2-mode binding to produce ordinary 2-mode release. With ordinary 2-mode alpine ski-bindings, there’s no possibility of release before ACL-rupture when abduction-loads enter a ski close-behind the tibia-axis, irrespectively of an ordinary 2-mode binding’s settings: a child’s setting could still block necessary release before ACL-rupture during these special Slip-Catch and Phantom-Foot loading conditions.
This phenomena occurs because the same centrally-located abduction-force that enters the ski at the ski/snow interface, acts over the length of the lower-leg (the ‘abduction-lever-arm’) to produce a large ‘abduction-moment’ across the ACL …
... unless a special 3-mode binding with additional lateral-heel release — also with special settings for the lateral-heel release mechanism — reads and reacts to abduction-loads generated by shaped-skis during highly-loaded Slip-Catch or Phantom-Foot events. Lateral-heel release stands directly in the kinematic path between a shaped-ski’s center-of-effort and the ACL. That special binding together with special lateral-heel settings is ACL-Friendly Howell SkiBindings.
The thin black line represents the unique ‘release envelope’ of ACL-friendly Howell SkiBindings. It operates in the white-space between the integrity-thresholds of both the tibia and ACL — and the pre-release lower-limit.
TWO IMPORTANT HOWEVER’S.
(a) — Special bindings with additional lateral-heel release MUST NOT pre-release. Pre-release can be worse than non-release (‘and settings are only a small part of how a good binding addresses anti-pre-release). —> Only Howell SkiBindings uniquely provide key know-how and advanced technology to block dangerous pre-release without high settings in all 3-modes of release.
Anti-pre-release is provided by ‘decoupling’ each of the 3-modes of release from each other — AND by decoupling each mode of release from innocuous skiing-control actions, such as edging.
Each mode in Howell SkiBindings is a separate system. 3 separate springs. 3 separate cams. 3 separate release mechanisms. Each mode has independently adjustable settings. Each mode operates without influencing the other modes. ‘And all 3 modes deploy off-center-pivots that filter-out compressive forces caused by ski-flex — which filtering critically blocks pre-release.
Howell SkiBindings block pre-release without high-settings.
Other bindings do not provide all of these combined features, benefits and advantages because Howell know-how has refined them during 50 evolutionary years of testing, including 20-years of focus purely on testing ACL-friendly skiing. No other binding provides you with this level of evolutionary revolution.
The secret sauce is that Howell SkiBindings accomplish these functions, simply. Simple equals durable and reliable.
(b) — No ski-binding, including Howell SkiBindings, can ‘prevent’ all skiing injuries. Injury can occur by simply falling down or by impact with an object. However, Howell SkiBindings aim to mitigate injury to the tibia, ACL, MCL, tibial plateau and meniscus by mitigating episodic non-release and by mitigating large cumulative loads that may be associated with chronic injury to those musculoskeletal elements — and Howell SkiBindings aim to mitigate injury to these and other human-systems by mitigating inadvertent pre-release.
