While the SPR leather is remarkably strong, having undergone a special tanning technique, and abrasion resistant, the steel toe is the key protective feature on this wedge work boot. It meets the ASTM F2413-05 1/75 C/75 Protective Toe Classification (can endure impact and compression up to 75 lbs.) and also the Electrical Hazard Standard. With the combination of the full-grain leather and safety features, this is one dependable boot.
