摘要:
Sports footwear with a vamp, and a lower support part including a sole unit, the lower support part having a lower portion or treading sole for contacting the ground and an intersole overlying the treading sole, wherein within said support part there is present at least a first insert containing elements which deform elastically when subjected to pressure and which are enclosed within an air-containing sealed casing positioned corresponding with the heel region of the sole unit. A further insert is positioned corresponding with the metatarsal region of the foot and also includes a casing containing elements deformable when subjected to pressure. The deformable elements positioned in the insert corresponding with the heel region have a different response to pressure-stressing than the elements present in the insert corresponding with the metatarsal region of the foot.
摘要:
A sports shoe insert is provided which includes a plurality of elastically deformable elements which extend vertically within a heel portion of a shoe wherein the deformable elements are shaped such that a substantially horizontal plane cross-section taken through each of the deformable elements is of a polygonal shape and a plurality of arm members respectively interconnect the deformable elements. The maximum cross-sectional area of the deformable elements is located in a central region thereof and at least the top portion of the deformable elements as a group form a concave seat for contact a heel portion of the person wearing the shoe. The arm members lie in a single substantially horizontal plane and interconnect the central portion of each of the deformable elements. The arm members and deformable elements form a plurality of interconnected triangular-shaped groupings as viewed from above. In addition, both the top portion and bottom portion of the deformable elements as a group may form a concave seat. A method of forming the insert is also provided.
