Puncture Resistant (PR)

Sole Puncture Resistant Footwear – Marking PR
Puncture resistant footwear includes a sole puncture resistant device (usually below the
insole) which reduces the possibility of puncture wounds to the bottom of the feet when the
wearer steps on sharp objects that penetrate the soles of the footwear.
The protective device must cover the maximum possible area of the forefoot and heel as the
construction will allow. Additionally the plates must be stamped to identify the
manufacture’s name (or trade name) and the month and year of manufacture.
