<p>A fastener, for instance a wide staple having holes in its legs, is heated to a temperature above the softening temperature of the material of a heel to be attached to a shoe. The fastener is then inserted through pre-formed slots in an insole of the shoe and pressed into the heel so that heat from the fastener softens the plastic and the fastener becomes embedded in the heel to hold it attached.</p> |
