The invention relates to devices and methods for monitoring one or more athletic performance characteristic of a user. An example apparatus includes a sensing unit adapted to be attachable to a shoe of a user, the sensing unit including a first sensor adapted to monitor an movement of a foot of the user while the user is in motion, the first sensor comprising a gyroscopic sensor, processing means for determining a first performance characteristic of the user based upon an output from the first sensor, the first performance characteristic comprising a foot strike location of a foot of the user upon striking a ground surface, and transmitting means for transmitting a data package representative of the performance characteristic to a remote receiver.

An element forming at least part of a midsole for footwear includes a top portion, a bottom portion, and at least two strut members disposed between the top and bottom plates for supporting the top plate a distance away from the bottom plate. The top, bottom and struts may be formed of different materials. Adjacent strut members have a C shaped cross-section facing in the same direction when the midsole resting its top or bottom portion is viewed from the side. The midsole element may further comprise a heel cleft to increase the flexibility of the sole. In a preferred embodiment, the strut members on the medial side are arranged at an angle to the strut members on the lateral side of the sole. The directional design provides flexibility and stiffness anisotropically to the sole in the longitudinal and lateral directions of the sole respectively.

The present invention relates to a cushion (20) for use in a shoe sole. The cushion (20) includes a medial chamber (26) for cushioning a medial portion of a wearer's foot, an internal chamber (40) disposed within the medial chamber (26) to increase a stiffness of the medial chamber, and at least one lateral chamber (24) for cushioning a lateral portion of the wearer's foot. The medial chamber (26) and lateral chamber (24) may be of unitary construction.

The invention relates to systems and methods for creating a foamed part. An example method includes providing a polymer processing system, providing a mold having at least one expandable mold cavity in fluid communication with the polymer processing system, mixing polymeric material and blowing agent within the polymer processing system to produce a unfoamed mixture, injecting a volume of the mixture of polymeric material and blowing agent from the polymer processing system and into the expandable mold cavity, and expanding the mold cavity to expand the unfoamed mixture within the mold cavity and form the foamed part.

A shoe cushioning system having a thin midsole, a first forefoot element, a second forefoot element and a heel element is described. The first forefoot element is connected to the midsole near the front of the forefoot region, the second forefoot element is connected to the midsole near the rear of the forefoot region, and the heel element is connected to the midsole in the heel region. The first and second forefoot elements are separated by a flex zone. The first forefoot element, second forefoot element and heel element each comprise an elastically deformable cushion with substantially planar top and bottom sides, and an attached cap structure. The first forefoot element may have a curved front edge and a substantially linear rear edge, wherein the curved front edge approximately follows the curved line defined by the metatarsal heads of the metatarsus bones of the foot. In addition, the second forefoot element may have a curved rear edge approximately in the region of the proximal ends of the metatarsals of the metatarsus bones of the foot.

摘要:
An object of footwear for children which allows adults to visually determine whether the shoe proper fits the child and can be adjusted in its effective size when it is determined that the shoe has become too small. The article of footwear comprises a fitting system comprising: (1) a substantially transparent window disposed in a predetermined location in the vamp so that when a wearer who has a foot that properly fits in the article of footwear puts on the article of footwear, a portion of a toe of the wearer can be seen through the window, and (2) a sizing member attached to the upper, the sizing member being placed within the opening against the heel portion to create a first effective size of the article of footwear, the sizing member being removable to create a second effective size of the article of footwear. The present invention also provides a method of determining when to adjust the effective size of an article of footwear and adjusting the effective size of the article of footwear.
