EN ISO 20345:2011 S1P CI SRC This safety rigger boot has been designed to keep your feet warm and dry as it features an insulating lining for warmth and comfort, plus it's made without a front seam and with a whole cut leg to keep out the elements. The innovative STS sole unit provides superior traction and stability across a wide range of surfaces and firefighter ladder grips for safe working at height. If you need to protect your toes from falling or dropped objects, Polar is up to the task with a strong composite toecap, and if you work on a site where nails or screws might be lying around, you’ll get superb underfoot protection with its flexible composite midsole. Even more good news? Getting the Polar boot on and off is no hassle with its pull loops - and we don't just sew our pull loops on: we rivet them to give you an extra dose of durability.
