Abstract
A cross-support member extends between the opposed side panels of an inverted U-shaped boot insert to prevent the side panels from collapsing toward one another. The cross-support member may be a separate structural element which is associated with the inverted U-shaped boot insert, or may be formed as an integral part of the inverted U-shaped boot insert (e.g., by partially cutting out the cross-support member from at least one of the side panels and/or by affixing the cross-support member to an interior surface of at least one of the side panels). The cross-support member may itself include lateral stiffening panels of desired geometry (e.g., triangular, rectangular, etc.) which are preferably formed as an integral part of the cross-support member by folding a lateral section of the cross-support member angularly out of the cross-support member's plane.
