S3 HRO welding boot with heat-resistant sole

Welding boot with a bellows tongue, no-lace quick closure and a sole rated to 300 °C.

Built for welders and foundry workers: full-grain cowhide upper with no exposed laces to catch fire, a side quick-release buckle and a bellows tongue that keeps sparks out. Nitrile rubber outsole withstands contact at 300 °C for a minute (HRO) and resists oil. Class S3 with steel toe and penetration-resistant midsole. Heat-insulated shaft lining.
