The sandal includes a sole having a toe portion and a heel portion, each of the toe and heel portions including an upper surface and a lower surface. A coupling mechanism is provided that couples the toe portion to the heel portion. At least one of the toe portion and heel portion includes an angled edge adjacent to the lower surface that allows pivoting of the sandal in a forward pivot direction, a backward pivot direction and/or a side cant direction.

Abstract: A golf shoe is provided which facilitates a stable swing by causing a golfer to pull his knees inward securely. Because of the inwardly pulled knees, a gap is inevitably formed between the outer edge of fore shoe and ground surface. This gap usually causes unnecessary body movement during swing, and eventually leads to a loss of swing strength and accuracy (this is referred to as a sway). In order to prevent the sway by avoiding formation of the gap, a special golf shoe sole is invented. When a golfer is taking a stance with his knees pulled inward the inner part of the fore sole is lowered and the outer part of the fore sole is raised. Technical function of the sole is achieved by installing the inner (1) and outer (2) fluid chambers which are interconnected by the solution moving velocity control path (3). During swing, the slope at the fore part of the sole is adjusted optimally by itself by the pressure distribution of foot.

Abstract: An adjustable dynamic, removable, mechanical foot leverage orthotic system is disclosed having a plate member positioned on top of one or more fulcrum member that are placed inside of a shoe. The plate is free to move within the shoe about the fulcrum to provide the wearer with mechanical improvement of abnormal, functional and associated foot pathology and can directly and indirectly effect the entire gait cycle. The foot leverage system can be integrated into the shoe design or can be inserted within a conventional shoe to create a foot leverage system. Methods of use and treatment are disclosed for the treatment of pes planus, pes cavus and tendonitis. The foot leverage system may also be used with the disclosed foot mapping system and method.

Abstract: An article of footwear includes a torsion system constructed of a material and configured to allow, in a pre-selected manner, rotation of a forefoot portion of the article of footwear relative to a rearfoot portion of the article of footwear about a longitudinal axis of the article while substantially precluding bending in an intermediate portion thereof.

Abstract: A sole capable of smoothly performing aori motion while absorbing a shock on a foot when the foot touches the ground with the outer side thereof is obtained. This sole comprises a central surface, a front bottom surface and a rear bottom surface. The central surface is formed substantially parallel to the bottom of the foot, and the front bottom surface has a first angle of inclination with respect to the central surface. The rear bottom surface has a second angle of inclination with respect to the central surface. A first elastic layer made of a material having higher flexibility as compared with the remaining portions is provided on the outer side of the boundary between the central surface and the front bottom surface to extend over the boundary. Thus, the first elastic layer smoothly deforms with a load when the central surface touches the ground, whereby aori motion can be smoothly performed while absorbing a shock on the foot when the foot touches the ground with the outer side thereof.

Abstract: A shoe and shoe sole insert having a heel portion slanted downwardly at a small acute angle from the medial side to the lateral side relative to the horizontal support surface, a forefoot portion slanted downwardly at a small acute angle from the lateral side to the medial side relative to the horizontal support surface, and a diagonally crossing ridge from the heel portion, across the midfoot portion to the forefoot portion. The heel portion has a central, resilient, compressible, calcaneal pad which is substantially unslanted, preferably with an air cavity therebeneath. The calcaneal pad protrudes upwardly above the upper surface of the heel portion. The metatarsal head pad extends upwardly above the upper surface of the forefoot portion. The pivot point or crossover point between the heel portion and the forefoot portion is preferably located a distance from the rear end of the insert equal to the insert length divided by 2.4.

Abstract: An article of footwear (10) having an initial contact portion (30) and a medial/forefoot portion (34). The initial contact portion (30) exterior sole surface is formed at a dihedral angle (38) to the sole surface of the medial/forefoot portion (34) such that the heel portion has a minimal thickness of material interposed between the foot (32) and the ground surface (40) at a postero-lateral edge of the sole structure, which means that foot flight continues until the foot moves closer to the ground (40) to delay impact and increase stride length. A high friction interface (72,172) is provided in a medial/forefoot portion of a shoe insole and low friction interface (74,174) is provided at the initial contact portion (30) of the shoe insole. The low friction area (72) reduces shearing on foot impact, and the high friction forefoot interface (72,172) eliminates sliding of the forefoot during foot push-off, to decrease wasted energy. Energy efficient and stride length increase are achieved.

Abstract: A sole member for an article of footwear, comprises a sheet of resilient material displaying cushioning and memory properties. The sheet has a generally longitudinal cavity with outwardly flared sidewalls that deflect horizontally in the presence of a downward force. The cavity is wider in the heel region and curves outwardly toward the lateral forefoot to create a path of least resistance that causes the center of mass of the human body to migrate laterally and thereby reduce predisposition to excessive pronation.

Abstract: A method and apparatus for providing shear waves in a marine environment in which a shear wave source penetrates the surface sediment of a water bottom. The shear wave generating source includes an actuator/reaction mass system mounted inside a structural ring of a housing section. A cross-shaped structure at the top of the apparatus serves as a passive reaction mass and as a moment arm support for reversibly motor driven propellers enclosed in shrouds at the outer ends of the structure. A thruster system provides dynamic positioning. The cross-shaped structure and housing section are connected by a structurally stiff member, such as a vertical tube. Pistons provide actuation against a reaction mass located within the housing structure, and motion of the housing structure generates shear waves which propagate in the subsurface formations.
