Abstract
An article of footwear, including a sole assembly and an upper, the article of footwear extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise from the outer sole assembly to an upper end, the article of footwear including a first fitting element as well as a second fitting element. The first fitting element includes a first envelope and a first sole of the strobel type, the first envelope being fixed to the first strobel sole at least with stitching. The second fitting element includes a second envelope and a second sole of the strobel type, the second envelope being fixed to the second strobel sole at least with stitching.
Claims42
An article of footwear comprising:
- a length extending from a rear end to a front end;
- a width extending between a lateral side and a medial side;
- a height extending from a bottom of an outer sole assembly to an upper end of an upper;
- the outer sole assembly;
- the upper comprising a first envelope and a second envelope;
- an inner sole assembly comprising a first strobel sole and a second strobel sole;
- a first fitting element comprising:
- the first envelope of the upper;
- the first strobel sole of the inner sole assembly;
- a first stitching extending through the first strobel sole and an edge area of the first envelope to affix together the first strobel sole and the first envelope;
- a second fitting element positioned within the first fitting element, the second fitting element comprising:
- the second envelope of the upper;
- the second strobel sole of the inner sole assembly;
- a second stitching extending through the second strobel sole and an edge area of the second envelope to affix together the second strobel sole and the second envelope;
- the first strobel sole comprising:
- a front end, a medial side, a rear end, and a lateral side;
- a periphery extending through the front end, the medial side, the rear end, and the lateral side;

A method of manufacturing an article of footwear, said method comprising:
- making a first fitting element to include a first envelope, having a first thickness and a first strobel sole, said making comprising assembling the first envelope to the first strobel sole to have a strobel construction by stitching an edge area of the first envelope to the first strobel sole;
- making a second fitting element to include a second envelope, having a second thickness, and a second strobel sole, said making a second fitting element comprising assembling the second envelope to the second strobel sole to have a strobel construction by stitching an edge area of the second envelope to the second strobel sole;
- making an outer sole assembly;
- affixing the second fitting element to the first fitting element and affixing the outer sole assembly to the first fitting element comprises at least one of the following:
- the first thickness of the first envelope, in an area of a junction with the outer sole assembly, ranges between 50% and 100% of a thickness away from said junction;
- the second thickness of the second envelope, in an area of a junction with the outer sole assembly, ranges between 50% and 100% of a thickness away from said junction;
- said affixing the second fitting element to the first fitting element comprising placing the second fitting element within the first fitting element and applying a permanent connection for permanent retention of the second fitting element in relation to the first fitting element.
