View Patent ↗A shoe construction utilizing a fluid containing chamber as a cushion. The shoe includes a stabilizer positioned in the shoe and having a heel portion in overlying relation to the cushion and a forward portion in overlying relation to at least a midfoot portion of the shoe bottom. The forward portion extends across a substantial portion of the inside width of the shoe where it is located to resist deformation of the shoe bottom under load from a user both in lateral bending and longitudinal torsion.
1. A shoe construction including:
a shoe upper with a forefoot portion, midfoot portion and heel portion;
a bottom member, said bottom member having an outsole portion with a forefoot portion, midfoot portion and heel portion and having a midsole portion in overlying relation to at least a portion of the heel portion of the outsole portion;
a sealed air cushion member located in the midsole portion in overlying relation to the heel portion of the bottom member and extending over at least about one-half of the central portion of the interior width of the bottom member heel portion; and
a resiliently deformable metal support member encapsulated into said midsole portion, said metal support member constructed and arranged to prevent said cushion member from deforming to the side and to provide torsional twisting resistance during loading of said cushion member, said support member having a heel portion and a forward portion, the support member heel portion being secured in overlying relation to the cushion member and covering a substantial portion of the length of the cushion member, the forward portion of the support member having a maximum width greater than about one-half the maximum inside width of the shoe upper at the locus of the maximum width of the forward portion to provide a rigid platform for engagement of the forefoot of the user, said forward portion extending forwardly from the support member heel portion along a substantial portion of the midfoot portion of the outsole portion, said forward portion of said support member having a frame member surrounding a through opening and also having a web member extending between and being connected to a portion of said frame member, whereby said support member provides resistance to torsional twisting about a longitudinal axis of said midsole portion.
2. The shoe of claim 1 wherein said forward portion of said support member extends into the forefoot portion of the shoe upper and extends across a substantial portion of the width of the forefoot portion of the shoe upper.
3. The shoe of claim 2 wherein said forward portion of said support member being perforated.
4. The shoe of claim 1 wherein the web member including a first member extending laterally between opposite side portions of the frame member and being connected thereto.
5. The shoe of claim 4 wherein the web member including a second member connected to and extending forwardly from the first member to the edge frame member and being connected thereto.
6. The shoe of claim 5 wherein the upper being a slip on style.
7. The shoe of claim 5 wherein said air cushion member having more than one sealed air chamber.
8. The shoe of claim 1 wherein said air cushion member having a top wall and a bottom wall with a plurality of columns secured to and extending between the top and bottom walls.
9. The shoe of claim 7 wherein said air cushion member overlying a substantial portion of the outsole portion heel portion.
10. The shoe of claim 1 wherein said support member extends along the length of the midfoot portion of the shoe upper and a substantial portion of the length of the forefoot portion of the shoe upper.
11. The shoe of claim 5 wherein said web member is constructed from a molded rigid polymer.
