They are nailed or screwed into the back or outer edge of leather soles and heels on dress shoes and boots.
Primary Uses & Benefits:
Prevents Wear: They protect the rubber or leather of the heel from wearing down unevenly—especially for people who strike the ground heavily on the outer corner of their foot.
Extends Shoe Lifespan: By taking the friction impact against the pavement, they keep the original heel intact, saving you from frequent cobbler visits.
Historical & Military Use: Historically common in military boots to preserve leather footwear during long marches on rough terrain.
The countersunk holes allow small flathead nails or short screws to sit flush so they don’t drag awkwardly.
