Definitions
- This invention relates to a method of adjusting ski boots to the anatomy of an individual skier in order that the skier can achieve ideal performance from the boot.
- Modern ski boots have a relatively flexible inner bladder and a relatively rigid outer shell, and the outer shell has a foot portion which supports the skier's foot and a cuff portion which supports the skier's shin.
- the foot portion has a sole adapted to engage the ski and support surfaces designed to engage safety bindings.
- Some of the boots have the foot and cuff made from a single piece, but most boots have the foot and cuff made from different pieces connected by some means designed to control the relative position or movement of the two pieces.
- Forward lean is measured in a plane which is longitudinal of the ski perpendicular to the ski's running surface, and control of forward lean is desirable to keep the skier's weight balanced and forward over the skis.
- Canting is measured in a plane which is transverse of the ski, and control of canting is important because changes in the canting angle determine whether the inside or outside edge of the ski predominates when the skier is running straight on a flat slope.
- This invention relates to a method of adjusting the ski boot to the anatomy of the skier in order that canting can be controlled exactly so that the skier can have a perfectly balanced ski with neither inner or outer edge predominating over the other when the skier is running straight on a flat slope.
- the method can also be used to adjust the ski to provide a precise predetermined cant fitted to the skier's anatomy where the skier desires to have predominant inner edges, but a ski racer will generally perform better with neutral inner and outer edges, because a predominant edge adds drag.
- Canting of ski boots has been controlled in the past by a variety of methods with varying degrees of inaccuracy. Thus, canting has been controlled by shimming, or shaving wedges from, ski boots until a plumb hanging from the skier's kneecap hangs over his big toe. Some ski boots are provided with a canting adjustment between the foot and cuff to permit the skier to adjust the canting angle to whatever angle feels best.
- canting has been done by recording the location of a plumb under the skier's knee while the skier stands in ski boots from which the bladders have been removed, and then shaving wedges from the boots to obtain the same plumb locations when the skier stands in the boots with the bladders in place; where this method has been used, the boots have first been altered to align the cuff perpendicular to the foot portion of the boot removing any initial canting angle which has been built into the boot.
- the skier's feet supported on orthotics are supported in the foot portions of the boots from which the bladders have been removed with the leg laterally unconfined. Preliminary alteration of the boot to eliminate canting angles is not absolutely necessary, so the method can be used with one piece boots and without changing the initial setting of a canting adjustment in such an adjustable boot. With the skier's feet thus supported and the feet spaced apart by the distance the skier normally uses during skiing, the lateral position of the skier's knee with respect to the foot portion of the boot is recorded.
- the skier's feet are firmly supported on the orthotics in the boots with the bladders in place and with the boots at the same spacing to produce a second lateral location of the knee to each boot.
- the orthotics may be mounted inside the bladder where they are worn during skiing whereas the orthotics were mounted directly in the shell of the boot in the first step of the method.
- the outer shells of the boots are altered to make the second lateral location equal to the lateral location recorded earlier.
- the alteration of the shell of the boot is preferably accomplished by adjusting a canting angle adjustment mechanism if one is provided in the boot.
- the skier's foot 10 is supported on an orthotic 12 inside the bladder 14 of a ski boot 16.
- the foot portion of the boot is indicated at 16a, and the cuff portion of the boot is indicated at 16b.
- the skier's leg is supported by the boot in a plane inclined to the vertical by the canting angle 18, and the leg is inclined in this plane by the forward lean angle 20.
- the boot is adjusted to the skier's stance as the skier's natural stance has been corrected medically by the orthotic in the following way.
- the bladders are removed from the boots and the skier stood in the boots on his orthotics. Note that with the bladders removed the boots are sufficiently loose around the skier's feet and legs so that the skier s feet, ankles and legs are unconfined by the boots. Both boots are used at the same time though only one boot is shown in the drawings, and the skier stands in the boots with his normal skiing foot separation and his normal skiing forward lean angle.
- This condition is illustrated in Figure 2, and in this condition the relative lateral location of the skier's leg or knee and the boot is recorded.
- This can be done in a number of ways, but it can be done conveniently by suspending a plumb 22 from the skier's kneecap and making a mark on the boot where the plumb strikes.
- the plumb 22 may be suspended on a string 24, and the string is supported adjacent to a predetermined point on the skier's kneecap.
- the change in relative lateral location of the knee and boot is noted, and the boots are adjusted to return the relative lateral location of the knee and boot to the original condition noted in step one.
- this adjustment is preferably made by adjusting a canting adjustment in the boot if one is provided, and in that case the adjustment may be made by another person while the skier is standing in the condition of Figure 2 with the adjustment continued until the condition of Figure 3 is reached where the original relative lateral location of knee and boot is achieved.
- boot adjustment which may be used in this way is the adjustment mechanism shown in U.S. Patent No. 3,739,498. Alternatively, adjustment can be made with the boots shown in Figures 5 and 6 which are sold as Lange Model ZT boots.
- the canting adjustment in the boots of Figures 5 and 6 is used by loosening a nut 30 so that the cuff 16b can pivot, while pin 32 mounted in the foot portion 16a, moves in a slot 34 in the cuff 16b.
- a pointer 36 operates with a scale 38 to record the cuff adjustment, and the nut 30 is locked when the proper canting angle is obtained.
- the adjustment can be made by mechanical adjustment of the boot.
- a wedge of material may be placed inside one side of the cuff of the boot with the magnitude of the wedge determined to be just sufficient to return the knee and boot to their original relative lateral locations.
- the boots are not provided with an adjustment mechanism for the canting angle, and the angle is made by altering the boot as explained above, it may be desirable to remove any initial canting angle built into the boot if this can be done without injuring the boots.
- some ski boots are provided with a built in canting angle of three degrees on the assumption that three degrees is a good average canting angle for average skiers, and that angle can be removed easily on some boots simply by relocating the hinge pins between the foot and cuff portions of the boots.
