ABSTRACT:
An edge trimming cutting tool is rotated against the edge of a shoe sole while a guide shield member, spaced from the tool, moves peripherally of the shoe in the groove formed at the junction of the sole and the upper. The guide shield member may be fixed or freewheeling but does not rotate, at least not at the speed of the tool, so as to prevent the guide from damaging the upper as by cutting, burning or the like.
