The Puma Safety 630777 Tornado Stone is a 6” boot that has a YKK zip side. The upper is made of water repellent premium nubuck leather and has a drawn-up scuff cap in the toe area to reduce leather abrasion when working on knees. This model has a lightweight fibreglass toe cap and contains a shock absorbing GelCell in the heel for the wearer’s comfort. As with all styles from the Scuff cap range, the Tornado Wheat is Electrical Hazard rated for greater protection against electrical shock for those operating in higher risk work environments.
