Abstract: The present invention provides a method for making ready-made shoes fitting individuals' foot shapes. This method includes the steps of forming a separate forefoot part and a separate rearfoot part, and connecting them detachably by means of a connecting means to form a shoe body. This makes it possible to easily produce sorts of shoes of different widths for each size by forming forefoot parts of different widths and/or rearfoot parts of different widths, selecting any of these parts of different widths and connecting the forefoot and rearfoot parts. This also makes it possible to easily produce sorts of shoes each pair of which has different sizes and/or widths, by forming forefoot parts of different sizes and/or widths and/or rearfoot parts of different sizes and/or widths, selecting any of these parts of different sizes and/or widths and connecting the forefoot and rearfoot parts.

Abstract: The invention provides a footwear article that may be worn in a first mode which permits easy removal, or may be worn in a second mode that provides a secure fit. The article includes an elastic region and a locking component on at least one of its sides. When worn in the first mode, the elastic region is capable of stretching which may increase the wearer's comfort and facilitates the removing the article and putting on the article on at a later time. When worn in the second mode, a fastener, such as a shoelace, is engaged with the locking component prior to tying. The engagement between the locking component and the shoelace restricts the stretching of the elastic material, thus, maintaining a tight securement of the article on the foot. A variety of footwear articles are contemplated by the invention including shoes and boots.

Abstract: A shoe that includes an expansible inner lining that snugly conforms to the wearer's foot and that permits the wearer's foot to grow at least one shoe size, and preferably approximately two shoe sizes. The shoe may optionally include a midsole disposed between the insole and outsole. The shoe may also optionally include an expandable counter that permits the heel portion of the shoe to adapt as the wearer's foot grows. The inventive shoe thus permits the wearer's foot to grow or expand widthwise and/or lengthwise thereby reducing the frequency with which shoes must be replaced and without sacrificing fit, support and comfort. The expansible lining may be constructed of any four-way expandable, porous material. A transparent toe portion and a fit indicator may be provided to assist in determining when the wearer's foot has grown too large for the shoe.

This is achieved by virtue of the act that a front thrust block (7) is fitted at the rear (5) of the front sole (2) and a rear thrust block (8) at the front (6) of the rear sole (3). The shoe is fitted with at least one adjustment means (11) which forms a force-locking connection with the two thrust blocks (7, 8), the jointed section (4) thus being adjustable by the adjustment means (11) to various lengths.
