摘要:
Impact attenuating/spring systems may include first and second body portions and at least one spring member at least partially included between the body portions. The spring member(s) may substantially enclose and/or be pivotally engaged with the body portion(s). The components of the impact attenuating and spring element may be arranged such that when a force is applied to the body portion(s), the spring member(s) will exert a counter force to urge the impact attenuating and spring element back toward its original orientation. The spring members may include one or more polymeric element that stretches under a tensile force. The impact attenuating and spring elements may be included in a piece of footwear or other device in a manner such that a user or a retailer (or others) can select an appropriate spring member (or portion thereof), e.g., depending on characteristics of the user or the intended use.

Impact-attenuation members include: (a) an impact-attenuating member and (b) a shear resistant member engaged with the impact-attenuating member. Another example impact-attenuation member includes a shear resistant member having a continuous wall that bulges outward on opposing sides when in an uncompressed base orientation. The shear resistant members may be structured and arranged to allow bending or compression against impact forces in one direction (e.g., when landing a step or a jump), but remain highly stable against shear or lateral forces in another direction (e.g., in a side-to-side direction). Such impact-attenuation members may be used in footwear products, including in athletic footwear.
摘要:
An article of footwear has an upper in a tented arrangement. The article of footwear includes a sole and an upper including a shroud. The article of footwear further includes a foot engaging system for joining a foot of a user to the sole, and a biasing system which includes one or more frame members that urges or influences the shroud away from the foot of the user. The one or more frame members may be coupled to the foot holding system on a medial and a lateral side. The article of footwear further includes a plurality of straps for holding the foot to the sole in which one of the straps engages the heel. The straps are located on an exterior surface of the shroud or alternatively they are located in the interior of the shroud. Air gaps are created between the shroud and the foot for ventilation. Several foot booties for holding a foot have aeration regions for providing air to ventilate the foot of a wearer. Further, the foot booties are combined with straps, in which the straps are disposed between the shroud and the foot booties. The upper has a flexible sheet of material that is interconnected with a plurality of frame members that urges the sheet away from the foot of a wearer. The upper may be removable and replaceable with the sole.
摘要:
A sports shoe with an integral tongue and acing system. The shoe includes an upper which is formed of a lateral portion and a medial portion. The medial portion extends across into the lateral side of the shoe and is configured to be placed beneath a longitudinal edge of the lateral portion. A plurality of eyelets or apertures are formed in the shoe and arranged in three rows. Two of the rows are located in the medial portion of the shoe and one row is located in the lateral portion of the shoe. A lining is placed on the interior surface of the medial portion such that the first and second rows of apertures are not exposed to the interior of the shoe. Respective pathways are defined between corresponding apertures of the two rows of the medial portion and between the medial portion and the adjacent lining for the accommodation of a lace therethrough.
摘要:
An athletic shoe including an upper and a sole. The sole includes a cushioning bladder including a sealed, fluid-filled tube disposed about the perimeter of the shoe. In one embodiment, the bladder includes lateral and medial portions extending about the heel and forwardly towards the forefoot to define a central region occupying a substantial portion of the heel and forefoot of the shoe. No portion of the tube extends within the central region, which may be occupied by ambient air or by a second bladder or chamber which is not in fluid communication with the tube. In an alternative embodiment, the bladder includes a tube having lateral, medial and transverse portions, with the transverse portion extending between the medial and lateral portions at the instep area of the shoe, to define a central forefoot region. In a further alternative embodiment, both a central forefoot and a central heel area may be defined. The shoe may further include a substantially rigid footframe disposed directly above the bladder and spanning the lateral and medial sides.
摘要:
A shoe having a closure system is disclosed. The shoe has an upper and a sole attached to the upper. A first strap member is attached to the medial side of the shoe at two longitudinal locations. A second strap member is attached to the lateral side of the shoe at two longitudinal locations. A first adjusting member is slidably coupled to both the first and second strap members. The first adjusting member is slidable along the first and second strap members towards the front of the foot to tighten the upper about the forefoot of the foot. A second strap member is slidably coupled to both the first and second strap members. The second adjusting member is slidable along the first and second strap members toward the rear of the foot to tighten the upper about the ankle and heel of the foot.
