Abstract: An athletic shoe system for running disciplines and a process for emitting and/or exchanging information concerning movement factors of running disciplines enabling the athlete to always be sufficiently informed regarding his/her training program that is in progress or completed. In particular, in an area of the sole that is less stressed during use, at least one free space is provided where a transmitter is housed which, via a sensor provided in the sole, can emit at least one output signal. In accordance with preferred embodiments, a transmitter in a first shoe of a pair of shoes receives the signals from the sensor and transmits emissions in correspondence with their receipt. The transmitted emissions are received by a remote receiver, that is linked with a computer, and the remote receiver receives the transmitted emissions directly from the transmitter of the first shoe and indirectly via a receiver and transmitter of a second shoe of the pair.

Abstract: A sole for an athletic shoe having an outer sole and a midsole formed of several layers, especially for running disciplines, is improved in such a way that stresses caused by pressure occurring during running and affecting the foot and the ankles are controlled in such a way that injury, especially injury to the ankles and premature fatiguing, is largely avoided. This is achieved by the midsole being comprised of a softly elastic inner part, a hard-elastic stabilizer and a cushioning piece that are formed into a unit and surrounded on all sides by a softly elastic sheathing.

Abstract: An athletic shoe having a shock-absorbing running sole which has at least one intermediate support extending at least approximately in parallel with a major plane of the running sole. The intermediate openwork support is disposed in a softly elastic midsole provided between an insole and a running sole. For obtaining a targeted reduction of shock stresses occurring to a varying degree in the individual sole sections, plugs are inserted into the openwork support. The plugs are made of a material that is harder than that of the midsole and are disposed vertically with respect to the noted major plane thereof, at least in the sections that are highly or maximally stressed during the running and possibly also in the adjacent zones.

Abstract: A pair of shoes for the sport of curling, according to the invention, has a first one of the shoes developed as a sliding shoe with a sole or a sole surface having a sliding area comprised of at least supporting areas of a material with a low coefficient of friction with respect to ice, and the other shoe formed as a run-up and drag shoe having a sole or a sole surface with at least tread areas of a material that has a high coefficient of friction with respect to ice, at least relative to that of the first shoe, and at least an outer surface of the toe cap of the upper being formed of a material that has a low coefficient of friction with respect to ice.

Abstract: An athletic shoe for track and field use, especially a running shoe, is formed in such a way that a flexible running sole is provided only in the area of its running surface and, thus, largely does not exist in the area of the longitudinal arch of the foot, and from the arch area to the heel, the running sole is rendered resistant to distortion by a reinforcement plate. Additionally, in the area of the longitudinal arch of the foot, the running sole has a supporting wall directed diagonally upward toward the inside of the foot that is fitted to the arch of the foot. Thus, a shoe for track and field use is obtained that is extremely light in weight, has high resistance to distortion and supports the foot well.

Abstract: A tennis racket having a hand-grip shell that can be moved longitudinally on the frame shaft. The hand-grip shell is formed of two half-shells made of a hard material which, by means of an elastic winding strip, a tube or several tube sections are pressed together so that the thus formed grip is held firmly on the shaft, but can still be moved longitudinally therealong. In addition, an adjusting device, such as an adjusting screw, is provided for adjusting the position of the hand-grip on the shaft. The result is that, in a simple manner, an easy individual lengthening or shortening of the grip can take place.

Abstract: For the simple mounting of a grip strip on a grip of a tennis racket without devices that damage the grip, a slot is provided in the bottom end of the hand-grip into which a grip strip can be inserted edgewise and where it can be fixed by a structural part of the hand-grip which holds the end of the grip strip in coaction with a tensional pulling effect of winding of the grip strip about the periphery of the hand-grip.

Abstract: A hand-grip for a racket, especially a tennis racket of the type having a hand-grip sleeve formed of longitudinally extending components mountable on a shaft of a racket frame connected to a hitting surface, according to the invention, utilizes at least two similar shell parts, made of a hard, elastic material, that have longitudinally extending edge portions which are arranged in such a way that, when the hand-grip sleeve rests firmly against the shaft, adjacent edge portions laterally overlap without end faces thereof abutting against one another. The hand-grip sleeve is provided with an elastic covering which presses the sleeve against the shaft on all sides.

Abstract: A running sole for athletic shoes, wherein exchangeably arranged cleats of a row of cleats are fastened by a common holding means which differs from known holding means of this type in that it is lighter in weight and simpler to handle. The cleats have base parts which are inserted into openings in the running sole and are fastened by spring or form-fitting means, so that they cannot twist about their longitudinal axis. The base parts have at least one borehole in alignment with lateral boreholes in the running sole in each row of cleats, so that, by means of the insertion of a single tube- or rod-shaped shaft into the lateral boreholes, all of the cleats of a respective row are fastened to the sole.

Abstract: A running shoe sole having a relatively thin outer sole layer of hard, wear-resistant material, a midsole layer resilient cushioning material and a heel sole layer, provided between the outer sole and midsole layers along approximately the rear half of the sole. In accordance with preferred embodiments, an outer, longitudinally extending portion of the heel sole layer spans approximately 2/3 of the width of the heel sole layer and is formed of a resilient cushioning material, while an inner portion spanning approximately the remaining 1/3 of the width of the sole layer is formed of a material that is of a hardness of approximately 10-20 shore durometer greater than that of the outer portion of the heel sole layer. This construction of the heel sole layer enables cushioning of the foot during lateral heel strikes occurring during running to be provided by the outer portion of the heel while the inner portion is able to act in a manner which limits pronation occurring thereafter.

Abstract: An otherwise conventionally constructed running shoe sole is provided with a rounded border having a radius of curvature of about 20 mm only along approximately the rear 50% of the length of the outer side of the midsole and heel edge layers, the remaining border area being provided with a conventional flaring or the like with the exception of a transition zone. In accordance with a modified embodiment, a convexly curved shock-absorber bar is incorporated into the sole and is outwardly covered by a layer of softer material which is provided with the outer curvature, and which increases the cushioning capacity of the sole during initial heel strike.

Abstract: An athletic shoe upper construction comprises a vamp with an elongated throat opening and a one-piece reinforcement of non-stretchable material. The one-piece reinforcement has a lacing hole reinforcing portion which is secured to the vamp of the upper adjacent to and surrounding the throat opening, and medial and lateral reinforcing portions in the form of an elongated strip extending from the lacing hole reinforcing portion to the featherline of the vamp in the mid-tarsal region of the respective sides of the vamp. Additionally, the width and location of the respective medial and lateral reinforcing portions is sufficient to at least span respective holes of two pairs of lacing holes provided in the lacing hole reinforcing portion.

Abstract: An athletic shoe, especially a jogging shoe, consisting of a tread sole made of rubber or a rubber-like synthetic resin, which sole is provided at least partially with cleat-like projections distributed over the tread surface and provided at the rim of the sole with additional cleat-like projections subdivided in the manner of a link chain. To create a fully elastic athletic shoe for jogging or other training purposes, wherein the cleat-like projections are to have a relatively low height in order to save weight, wherein yet a satisfactory gripping effect is to be ensured even under unfavorable ground conditions, the cleat-like projections are fashioned, on their sides which come into contact with the ground, with blade-like projections extending essentially in parallel to one another, which increase the shock-absorbing effect and simultaneously enhance the gripping effect.

Abstract: Athletic shoes, especially soccer shoes are known comprising a tread sole of rubber or another material having rubber-elastic properties, which sole is provided at least partially with nubs uniformly distributed over the tread and forming a unit with the tread sole, the longitudinal axes of these nubs being aligned obliquely with respect to the sole surface. In order to broaden the area of usage of such athletic shoes, especially to render such athletic shoes suitable for sports on artificial grass or on hard courts, the obliquely oriented nubs are arranged exclusively in the areas of the ball of the foot, the ankle joint, and the heel along the rim of the sole as the outermost nub row or as external nub rows. The nubs located in the marginal zone of the tip of the sole are arranged with their longitudinal axes at least almost perpendicular with respect to the sole tread and exhibit a lower profile height than the obliquely oriented nubs.

Abstract: Athletic shoes, particularly tennis shoes, are known which are provided with an ankle support in the zone of the arch of the foot (plantar arch) between the ball and the heel. In many such athletic shoes with ankle joint supports, the tread sole is fashioned with a corresponding constriction in the ankle region so that the inner ankle support is not shored up in the direction of the tread surface. To prevent such athletic shoes from buckling or bending flexurally in the ankle zone under high stresses, or even "break through", several discrete supporting profiles of varying heights are provided at the tread sole, the enveloping line of which on the free ends of these supporting profiles on the tread side lies at least approximately in the plane of the adjoining tread sole parts.

Abstract: A sole made of rubber or other elastic material for shoes especially sport shoes, having a tread with studs or cleats distributed at least on part of the tread with at least some of the studs or cleats being inclined relative to the tread as the studs or cleats formed with a plurality of arms at least some of which extend at an angle of about 30.degree.-120.degree. with respect to each other and form an angle of about 10.degree.-85.degree. with respect to a base surface of the tread. According to some embodiments, the arms of the studs or cleats are of equal length, while in other embodiments the arms of the studs or cleats are of unequal length. Additionally, some embodiments extend at different angles with respect to the base surface of the sole or are formed of cleats having differing numbers and/or shapes of the arms of the tread. In some embodiments, the arms of the cleats are themselves provided with a tread of seven different possible types.
