     Howell Mars 4 - 12 DIN — for performance-skiers weighing over 130 pounds.

•  Same technology as Howell racing bindings — but with lower settings;  slightly narrower off-center toe pivots;  housings made of engineering-grade resins.

•  Off-center pivots in all 3 modes of release block adverse pre-release.

•  Industry-leading elasticity further blocks adverse pre-release.

•  Extra-wide 4-point lateral boot contact toe & heel — top & bottom — for powerful carve control.

•  Lite.  Strong.  Pure alpine.  No pins.

•  ACL, MCL, meniscus, tibia friendly.  Proven biomechanically.



    Toe and heel housings of super-tough engineering-grade, non-hydroscopic, Nylon-12 with 45% long glass fiber.  

    Top surfaces of toe-pads and heel-pads are thick, virgin, DuPont Teflon.  

    Non-corroding, 303 stainless-steel inner workings provide durable, reliable, long-term function. 

    Utility-patented, low 22mm stand-height reduces cumulative, long-term, stress on ACL, MCL, meniscus and tibial plateau.  Low standheight allows most race-plates (not included) while meeting FIS racing-rules.

    0°-ramp angle provides natural athletic stance with all boot sole lengths (depending on internal boot ramp-angle).  

    Adjustable toe-cup height to fine-tune boot-fit after extensive use, or for proper-fit with boot-canting.

    Floating Mounting System mitigates mounting-screw pull-outs & provides natural ski flex.

    GripWalk sole or ‘standard alpine sole’ compatible.  Both options included.  We recommend non-GripWalk boots — to provide tibia-plateau integrity.

    Extra toe-pads and heel-pads with Teflon tops — attachable with simple re-mounting of toe or heel — to replace worn Teflon;

    Deep retracting brake-arms provide maximum edge-angle without booting-out;

    Anticipated compliance with all DIN/ISO safety standards (specifically, DIN/ISO 9462, 9465 and 11087);

    Individually tested and calibrated;

    Lifetime Limited Warranty;

    brake retainers for edge/base-prep;

     2 sets of ski-brake widths:  70-80mm;  80-90mm**;

     Precision metal mounting jig;  4.1mm-Ø DIN-standard drill-bit;  4.0mm-Ø DIN-standard tap;

     Cant Kit (0°-standard;  1°;  2°) including longer mounting screws;

      Detailed, simple, mounting instructions;  mounting certification;  and 24/7 on-line AI service.

** Howell SkiBindings is against (a) ski waist widths greater than 90mm AND against (b) all 'pin-bindings' (except Trab TR2;  and Shift, though do not fall with Shift bindings while in the touring-mode, and Shift bindings are not ACL friendly) — due to their association with severe, high-energy, tibia-plateau fractures.  This type of skiing injury matches the growth of fat-skis and pin-bindings.  The high-energy nature of this type of fracture involves multiple-fragments, difficult surgical reconstruction, and 10 to 15-months of aggressive rehabilitation.  Fat skis and/or pin-bindings on firm snow are a serious problem for the sustainability of our beautiful sport.  (‘Pin-bindings’ are hardly “tech”.)
