Abstract: An arch support having an upper surface portion, a formed elastomeric lower cushion portion, and a stretch-resisting mat of interwoven nonelastic fibers integrally attached between the upper surface and lower cushion portions to resist lateral and longitudinal stretching during use. The stretch-resisting member may take a variety of shapes to conform to the needs of various foot arch shapes. The arch support has a preselected configuration with dimensions that fall within preselected ranges to complement and provide appropriate support for selected foot arch categories. The arch support may be fitted to an individual user using a system which has a plurality of arch supports of preselected configurations to complement the shape and positioning of the arches of a variety of users' feet and an open top cradle for simulating the fit of the inside of a shoe on which the arch support is rested to have the user try it for fit.
