Abstract: A shoe spring kit for a shoe includes a V-shaped spring portion having a lower platform portion and a raised springboard portion, the raised springboard portion intersecting the lower platform portion at an intersection point to form an angle relative to the lower platform portion such that the raised springboard portion is spaced apart from the lower platform portion by a distance at a location opposite the intersection point. The raised springboard portion is configured, at a static position, to bend and move closer to and away from the lower platform portion so as to provide a cantilever spring effect. The V-shaped spring portion can be placed inside of the shoe or outside of the shoe.

Abstract: An article of clothing includes, in one embodiment, four alternate layers made of (i) an air permeable material such as cotton and (ii) a non-air permeable material such as polyethyleneterephalate. Two intermediate layers both include a plurality of throughholes therein covered by the outer layers. The throughholes of the second layer are laterally offset from the throughholes of the third layer such that no direct path is provided through the throughholes between the intermediate layers so that the bites of insects are resisted. In another embodiment, two layers are provided each including a pattern, e.g., alternating stripes of an air permeable and a non-permeable material. The stripes of the two layers are offset so that non-permeable material of the two layers, taken together provide an insect barrier.

Abstract: A man's shirt is provided which is made of conventional woven non-stretch shirting material but which includes elastic elements woven therein at the shirt sides in the area of the torso. These elastic elements shape and sculpt the shirt in this area and prevent bunching and creasing of the shirt. A related method begins with a bolt of a basic shirting material with discrete sites at which the elastic elements are provided and uses computer-controlled cutting of the shirting material relative to these sites to provide component parts of the shirt which, when assembled together with other component parts, produce a shirt with designed-in shaping.
