Abstract: A system with pressure sensors (5, 12), transmitters (8, 16, 18) and receivers (10, 21) provided in running shoes (2, 3) that upon the shoes (2, 3) leaving or contacting the ground (14) emit and/or receive respective signals (S1, S2, S3, S4). Signals (S1, S2, S4) are formed which are received by a receiver (21) that is independent of the shoes and which are evaluated in an evaluation unit (23). The distance between the feet (FA) is determined from when a front striding foot hits the ground and the rear foot lifts off based upon the timing between the signals using an approximating formula. From the times and the stride length other values movement characteristics of the user may be determined as well.

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: Athletic shoe sole having cleats with exchangeable gripping elements designed such that the threaded mounting studs for gripping elements are firmly anchored to the sole, and that the associated caps of the gripping elements can be detached therefrom without damage or destruction to the threaded studs. This is achieved in that each threaded stud (2) and the screw-on cap (5, 5a) is in the shape of a cone whose broad base faces the shoe sole (1). The thread is a single or multiple thread (4) having only partial turns of screw threads. Finally, run-on surfaces (12, 13) effective during screw-on of lock elements (10, 11) of the cap are less inclined relative to the plane of the sole (1) than the flank surfaces that act as locking surfaces (14, 15) which are also inclined.

Abstract: An athletic shoe sole with cleats having exchangeable gripping elements designed in such a way that the gripping elements can easily be exchanged without incurring diminished stability or premature wear to the shoe sole. To this end, stud-shaped holding elements (2) are provided with a flange (3) with which they are molded into the shoe sole 1. Shoe sole (1) itself, or a portion associated therewith, forms coaxially to the stud-like holding elements (2), a minimum of one raised area (28) which surrounds at least one recess (25) between these raised areas (28) and stud shaped holding elements (2). Finally, the respective recesses (25) are engaged correspondingly shaped projecting elements (26) of the gripping elements or the gripping element components, respectively, which are in the form of caps (9).

Abstract: Athletic shoe sole with cleats having exchangeble grip elements that are snap-locked to a mounting stud. The grip element can easily be inserted and removed again, without impairment of shoe sole stability or danger of damage thereto, by the provision of interactive engagement formations, comprised of a minimum of one raised area 16, 17, 26 and a complementary recessed area 19, 28, that have at least one inclined surface that produces a relative axial shifting between the gripping element and mounting stud when the gripping element is rotated about its longitudinal axis. Preferably, the raised areas 16, 17, 26 are arranged such that, in the snap-locked condition, they do not have operative contact with the recessed areas 19, 28, but can be brought into operative contact by rotating grip element 11 around its longitudinal axis x, and thereafter the grip element 11 can be pressed out over the catch point of the snap-lock device or snap-lock devices 8, 12 to release the grip element from the mounting stud.

Abstract: A sole for a sport shoe, especially of the type used for running over great distances, and having a one or multilayered midsole made of soft, elastic, shock-absorbing material disposed between an insole and an outer sole of abrasion resistent material, the midsole being provided with vertically oriented damping members possessing harder resiliency characteristics than the material of the midsole. For the purpose of improving the mounting of the damping members and for enlarging the degree to which the damping characteristics can be adjusted, the damping members are formed as damping discs (6) that are exchangeably insertable in cylinders (5). A piston (8) is received in each cylinder for pressing against the damping discs (6).

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: 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 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: An athletic shoe, particularly a soccer shoe, with extreme flexibility in the ball area and, preferably, in the mid-foot joint area as well, is achieved by the provision or ribs in these areas on the contact side of the sole as well as on the insole side. The ribs form a continuous undulating band consisting of wave crests and valleys, and may be formed as a unitary part of the sole or may be a separate component made integral with the sole during manufacture thereof, such as by the sole material being injected or case around them.

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.
