Shoe heel assembly and method
A shoe outsole has a heel post extending outwardly therefrom. An outer heel cover has a hole for receiving the heel post in an assembled position. The heel post thus acts as a convenient positioning guide for the heel cover. A plurality of fluid-filled heel cushioning members at least partly surrounds the heel post between the outsole and the cover in the assembled position, for cushioning heel impacts during use of the footwear. A plurality of dividers on the outsole extend radially of the heel post, and position each cushioning member between a pair of the dividers. The dividers thus act as convenient positioning guides for the cushioning members. The cushioning members have different resistances to compression for adjustably cushioning heel impacts during use of the footwear.
1. A heel assembly for footwear, comprising:
an outsole having a heel post extending outwardly from the outsole;
an outer heel cover having a hole for receiving the heel post in an assembled position; and
a heel cushioning component at least partly surrounding the heel post between the outsole and the cover in the assembled position, for cushioning heel impacts during use of the footwear, the heel cushioning component including a plurality of fluid-filled cushioning members spaced apart angularly around the heel post.
2. The assembly of claim 1 , wherein the outsole has a plurality of dividers extending radially of the heel post and spaced angularly apart, and wherein each cushioning member is positioned between a pair of the dividers.
3. The assembly of claim 1 , wherein the outer heel cover is constituted of a wear-resistant material.
4. The assembly of claim 1 , wherein the outer heel cover is adhesively mounted on the cushioning members in the assembled position, and wherein the cushioning members are adhesively mounted on the outsole in the assembled position.
5. The assembly of claim 1 , wherein each cushioning member is a sealed cushion filled with air.
6. The assembly of claim 5 , wherein each sealed cushion includes a pair of juxtaposed sheets, each sheet of the pair having a plurality of indentations extending toward the other sheet of the pair, and wherein the indentations of the sheets of each pair abut, and are integrally connected to, each other.
7. The assembly of claim 6 , wherein each indentation has a generally hemispherical shape, and wherein the indentations of the sheets of each pair are integrally connected to each other at common welds laying in a plane centrally between the sheets.
8. The assembly of claim 1 , wherein the cushioning members are sealed cushions having different resistances to compression.
