The present invention provides an interchangeable shoe footbed cartridge system. The system includes a footbed such as a midsole, insole or a sockliner. A cartridge is inserted into or otherwise attached to the forefoot section of the footbed. Multiple cartridges of varying depths, widths and/or lengths may be provided. The wearer can select a cartridge to achieve a desired fit. Because right and left feet may be of different sizes, different cartridges may be chosen for each foot. Furthermore, the user may swap cartridges depending upon different conditions, or to change the stiffness of the cartridge. Additionally, a slipcover having a stretchable portion may be placed over the cartridge system. The cartridges enable a footwear manufacturer to produce fewer shoe sizes while fitting more of the population. This reduces manufacturing, shipping, warehousing and accounting costs. All levels of the supply chain, as well as the end customers, will greatly benefit from the method of supplying footwear.

There is disclosed an internal sizing apparatus comprising a pneumatically activated probe that moves axially within a shoe and non-destructively measures the interior dimensions of the shoe. A linear pneumatic actuator is mounted between a heel piece and a probe. A linear potentiometer is mounted above the actuator and also connects to the probe. The apparatus is inserted into a shoe with the heel piece seated against the interior heel portion of the shoe. A computer system controlling the actuator extends the probe linearly into the shoe until the probe contacts the toe portion of the shoe. The potentiometer then measures the linear distance traveled by the probe and thus determines the internal linear dimension of the shoe. Depending on the type of probe, three-dimensional internal measurements of the shoe can also be quantified.

A method for shoe fitting includes identifying outer foot outlines defining outer boundaries of feet of a user, and inner foot outlines defining weight-bearing areas of the feet in a computer-readable image of the feet. Weighted foot outlines are calculated based on the outer and inner foot outlines. A plurality of unfilled shoes are defined by a common shoe last having a last bottom outline, and sets of different left and right interchangeable insole adapters for insertion into the unfilled shoes are provided. The adapters match the last bottom outline and have respective adapter outlines. The weighted foot outlines are compared with the adapter outlines, to determine an optimal shoe size of a pair of shoes out of the plurality of the unfilled shoes, and to select left and right insole adapters from the sets of the interchangeable insole adapters whose adapter outlines best match the weighted foot outlines.

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.

An improved expandable shoe and inner assembly are disclosed. The expandable shoe includes an outer shell and an adjustable inner assembly is disposed within the outer shell. The inner assembly has a first board portion and a second board portion in overlapping engagement with each other and a control to adjust the position of the first board portion relative to the second board portion. A lighted visualization window provides a visualization window to the inner assembly. The inner assembly may include size markings through the visualization window so that a size of the adjusted shoe may be determined as shoe size is adjusted.

The invention provides a device for selecting a size by body measurement. The device comprises a foot length measurement device, a measurement control unit and a control device, wherein the foot length measurement device comprises a pedal, a positioning part, a measurement plate and a distance-measuring sensor; the measurement control unit is respectively and electrically connected with the positioning part and the distance-measuring sensor and used for receiving a foot length measurement triggering signal to control the distance-measuring sensor for carrying out distance measurement and calculating a foot length value according to the measurement value of the distance-measuring sensor; and the control device comprises a shoe size selecting unit, wherein the shoe size selecting unit is used for receiving the foot length value sent by the measurement control unit so as to compute a shoe size. According to the device disclosed by the invention, no tape measure is need for measurement, the proper shoe size can be quickly and accurately selected, and the characteristics of high efficiency and high accuracy are achieved. In addition, a non-contact human body three-dimensional measurement technology is not needed, and the measurement of the foot length can be realized only through simple mechanisms. Thus, the device for selecting the size by body measurement, disclosed by the invention, also has the characteristics of simple structure, convenience for operation and low cost.

Waterproof, breathable socks, booties, shoe inserts, and footwear assemblies containing the shoe inserts are provided. The booties and shoe inserts include a laminate of a seamless ePTFE membrane and at least one textile. The bootie is conformable over a range of sizes and shoe shapes, and may be shaped to fit numerous sizes and shapes of asymmetrical shoe lasts. The bootie may shrink to fit, or, alternatively, be stretched to fit, an asymmetrical last having a desired size to form a shoe insert. Such a conformable bootie eliminates the need to have multiple sizes of shoe inserts correlating to particular shoe sizes. In embodiments where the ePTFE is seamless and continuous, the shoe insert eliminates the need for a waterproof seam tape, which is conventionally used to make shoe inserts waterproof. Methods of forming the socks, booties, and shoe inserts are also provided.
