The attachment region (11) of the sole (12) is arranged recessed by the thickness of the pedal plate (13) relative to the base surface of the sole (36) around the attachment region (11), so that the bottom of the pedal plate lies substantially flush with the bottom of the sole.

Abstract: An insole for a shoe, and method of manufacture, comprises a bottom layer formed of cushioning material, and a top layer formed with apertures, which, in various methods of manufacture, is embedded into the bottom layer so that the cushioning material forming the bottom layer extends at least partially into the apertures in the top layer. The coefficient of friction of the top layer of the insole which contacts the foot of the wearer is variable and chosen to control the movement of the foot along the insole depending upon the type of activity and playing surface for which the shoe is designed.

Abstract: The inner shoe in the form of a boot has, in the region of the instep, a deformable narrow zone of lesser resistance (2) which extends across the front part of the upper and on either side of the instep towards the end of the foot and defines a tongue-shaped zone (4). The upper (3) is thus able to flex forwards, while the tongue-shaped zone (4) is able to press against the instep without being retained by the upper.

Abstract: The boot is equipped at the rear with a cable-type clamping and closing device consisting of a lever (9) mounted on a support piece (10) displaceable on a rack (11). This rack is preferably movable and connected to two cables (23, 24) for clamping the foot, the upper (4) being closed and clamped by a cable (17) attached to the tensioning lever (9) and acting on the rack in a direction opposite to that of the other cables (23, 24).

Abstract: The present invention relates to a support adjuster device for the quarters of ski boots including a shaped body, pivoted to the quarter of a ski boot, and means for adjusting and releasably locking the shaped body in any desired position with respect to the quarter. The device enables a skier to adjust the abutment of the quarter on the leg as desired through easily operable means.

Abstract: This invention is for several preferred embodiments of sole protectors for use with shoes for protecting the feet of the user. In one embodiment of the invention, a sole protector is provided in the shape of a sole of a boot formed of impenetrable material encased in a protective coating of material. The material for forming the impenetrable sole protector can be puncture proof, metal, and woven. In the second embodiment of the sole protector, the sole protector is formed of similar material, but with the sole formed of two sections hinged together. Additionally, the sole protector is designed with an arch height of a standard boot.

Abstract: A suction-ventilated shoe system, which has air-exit ports located on the outer surface of said shoe, preferably in the midsole region, is provided. Said suction-ventilated shoe system contains a novel, multivented, suction-operated insole that enables the entire surface of said insole to be uniformly ventilated. Each air vent of said multivented, suction-operated insole contains its own independent, foot-operated, air-suction pump means, whose exhaust air is directed to exit the shoe via special air ducts that are connected between said insole's air-suction pump means and said shoe's air-exit ports. Each air-suction pump in said suction-operated insole has its own associated, one-way, air-valve means. A multiplicity of air vents may now be located anywhere over the entire surface of said insole and still maintain equal, air-suction, operating efficiency for each and every air vent.

Abstract: A ski boot includes a rear shell at least partly formed in one body with its sole, and a front shell pivoted to the sole in an arrangement turnable forwards for entry of a wearer's foot into the ski boot. Forwardly turnable construction of the front shell allows smooth entry of the wearer's foot without enlarging the construction which cannot afford good fit to and sufficient hold on the wearer's foot and one body construction of the rear shell with the sole well withstand rearward tilting of the wearer's leg during skiing.

Abstract: A convertible shoe is provided and consists of a shoe bottom that has a formed outside portion, a middle shank and a raised heel; a shoe top that has a midsole, an insole and an upper vamp portion and fasteners for removably attaching the shoe top to the shoe bottom.

Abstract: An insole includes a top wall and a bottom wall constructed from an air-impervious material. The top and bottom walls are heat-sealed at a durable side wall ridge to form an envelope having a heel, intermediate and front zones. A porous pad is contained within the envelope. Vent openings are provided only at the intermediate and front zones for ingress and egress of air from the envelope as the wearer walks on the insole. The total area of the vent openings in the front zone is greater than the total area of vent openings in the intermediate zone, thereby facilitating movement of air throughout the insole without imparting excessive pressure at the side wall ridge.

Abstract: This invention relates to shoesoles for the bottom of golf shoes and especially to shoesoles provided with, in addition to conventional spikes at the forepart and heel, ground-engaging protrusions distribution along the inner and outer marginal edges of the soles to enhance the stance of the golfer.

Abstract: A closure and securing device, particularly usable for ski boots comprising a rear quarter rearwardly having a transverse set of teeth with which there interacts a rod-like element embracing said rear quarter. Said rod-like element is operatively connected to one or more pressers placed at the foot instep region and/or at the heel region.

Abstract: A high boot has a frame with cradles for supporting the leg and the instep, a rear support member connected to the frame and an operating lever pivoted relative to the frame. A cable is attached to the operating lever, which acts on the frame, upon pivoting the operating lever, so as to tighten the frame and the rear support member together or to release the frame and open the boot. A releasable stiffening device is interconnected between the front lower part of the boot and the rear support member to stiffen or release the boot.

Abstract: The closure and adjustment device is particularly for ski boots comprising a front quarter and a rear quarter pivoted to a shell. The rear quarter is connected to at least one mutually movable part of the boot through at least one connecting element. The rear quarter and the connecting element are provided with a set of teeth and a bar respectively for the adjustment and locking of the position of the connecting element, for effecting adjustment of the closure of said quarters.

Abstract: A ski boot consisting of an outer shell and an innerboot installed inside the outer shell. The outer shell is formed out of thermoplastic synthetic resin material mixed with a desired weight ratio of whisker. Mixing of whisker not only increases the flexural elasticity of thermoplastic synthetic resin material but also reduces the elastic distortion of the outer shell. Further, the abrasion-resistance of the outer shell is improved.
