OMFit© Origination

originator

The Zipfit© and OneMinuteFit© man is (Sydney born) Sven Coomer. He developed and perfected the recent application of “OMFit” molding compound, seen here holding enough goop for 3 pairs of his Zipfit inner boots. After 25 years of competing and coaching in 7 sports through Olympic level, and studying engineering and industrial design, Sven began designing and developing ski boots with Nordica in 1970. That was in the transition from leather to plastic boots. His contributions there laid the foundations for the state of the art in today’s ski boots. In 1978 he opened a ski boot fitting and orthotics development shop at Mammoth Mountain, California, from which came more famous boot models, boot fitting schools and Superfeet. In ’88 he began Zipfit to develop the missing links, the orthotics and inner boots.

OMFit is a proprietary formula of granulated cork and dry-ceramic “clay” binders. These combine to create the optimum viscosity and density to work in the extreme and most demanding environment of ski boots. The OMFit is perfected to perform within his other unique Dynamic Molding System. This enables the OMFit to adapt and work with you, allowing your anatomy to settle into the optimum and most efficient relationship and effective support within your ski boots. This changes constantly whether you are skiing straight or carving high speed or slow speed turns. It is not a casting of one passive position, as with foam or silicone injected liners. Sven was also accountable for developing the best ever foam liners and patented silicone liners.

Dozens of formulas were tried in evolving this one functional recipe that works; responding perfectly with your anatomy dynamics and body heat within the complex demands and environments encountered in skiing. Cork is superior because it never compresses, deteriorates or shrivels-up the way all of the synthetic materials, foams and fillers did in extended testing. Cork yields under pressure and vibration without deforming or losing support and always returns to original memory. OMFit is also organic, the best insulation and the most ergonomic feeling around your anatomy. In addition, it lasts for at least 600-700 days of hard skiing. The paste is proven to promise you the best fitting, warmest, most comfortable, supportive and best performing ski boots you could ever imagine.

OMFit© Material

OMfit© is a proprietary composite formulation of granulated cork with a "ceramic" binding-adhesive agent.  It has a unique capacity to stabilize the feet and lower legs in both comfort and warmth; that means heel hold-down. OMfit's very particular self-molding viscosity and density, and it's specific sensitivity to temperature has been formulated and perfected over 4 decades from the original cork-and-oil flow formula of the early 70's.

OneMinuteFit©, (OMfit©) is a proprietary composite formulation of granulated cork with a "ceramic" binding-adhesive agent.

It has a unique capacity to stabilize the feet and lower legs in both comfort and warmth; that means heel hold-down. OMfit's very particular self-molding viscosity and density, and it's specific sensitivity to temperature has been formulated and perfected over 4 decades from the original cork-and-oil flow formula of the early 70's.

The original cork-flow is still being used today in all of the top racing boots as the best fitting, most comfortable and supportive medium. Now the much improved OMfit© and the respective containment sacks, in both tongues and ankle-heel areas, also includes the optional SPOTFIT© precise dosing injection or extraction capability.This results in a unique customized performance-support and comfort-fitting system without compromising any essential features.

cork omfit comparison

By comparing the old “cork flow” with OMFit© compound ... When heated side by side the OMFit, expands about 10% and becomes softer, more fluid and moldable. Note that the cork flow does not expand or respond at all. Here the OMFit has absorbed enough heat to deform the plastic cup and this property enables the compound to exchange heat with your body and keep you warm all day.

Dynamic Fit Sack

fit sack detail

The transparent ankle-heel sack showing the curved U-shaped heel huggers that taper towards the front (right), the overflow sack which is initially empty and the SpotFit© injection tab (sealed here). The subtle flexing action of the leg shaft pumps the OMFit© back towards the opening and compresses it into the heel huggers. In rare cases when the shell is too narrow for the heel width this circulating process is blocked and needs to be primed each time the boots are put on.

  • The OMFit never hardens or catalyzes and this is one essential Zipfit ingredient.
  • The OMFit is the most resilient, supportive, protective, shock absorbing, heat exchange and insulative material ever devised for boots.

SPOTFIT Injection

The OMFit compound can be added or removed using the SPOTFIT injection system into different areas of the boot.

The tongue and heel pocket can be independently manipulated through fittings on each of these pieces. Since the material remains fluid at room temperature, but even more so when warm. You may find that manipulating the OMFit material on a warm liner, or with warm compound is easier to complete.

Upon adding or subtracting material, it is important to follow the fitting steps

The proprietary SPOTFIT© injection system allows the operator to inject precise doses of additional extra OMfit molding composite - exactly where it is needed.

The proprietary SPOTFIT© injection system allows the operator to inject precise doses of additional extra OMfit© molding composite - exactly where it is needed. The operator can also extract OMfit when the fitting is too tight. While either process is rarely needed it is comforting to know that the option is there if it is ever needed and the process only takes a few minutes.

The tongue is the best place to start injection as the tongue holds the foot down and back.

The tongue is the best place to start injection as the tongue holds the foot down and back. After injection of the warmed OMfit, wear the boots again for a longer period of time, and if at all possible go skiing, to allow the material to adapt dynamically before deciding to inject more or perhaps to inject the ankle pockets.

injecting warm OMfit behind the ankles

If "heel swiping" and "hoisting" (see fitting instructions) is not sufficient to restore the original heel-hugger hold-down, then you may consider SPOTFIT injecting warm OMfit behind the ankles. Then wearing the boots, to disperse the composite dynamically as your heels and ankles suggest, especially while skiing.

When the fitting remains tight, despite heating the shells and skiing you can consider extracting the excess OMFit

When the fitting remains tight, despite heating the shells and skiing you can consider extracting the excess OMfit (from a warm liner) with your fingers. Once again, refit the liners into a HOT shell and preferably ski a few runs to resettle the definition perfectly.
