Product Description
Waterproof western pull-on work boot with a steel safety toe and EH protection, built for the shape of a woman's foot
The Red Wing Rio Flex is a 10-inch waterproof, western-style pull-on work boot built specifically for the shape of a woman's foot, ready for long days in construction, farming, ranching, and manufacturing. It pairs a steel safety toe with built-in electrical hazard (EH) protection, slip resistance, and waterproofing to ASTM F2413-24 (I/C, EH, SR). The Dynamic Fit System and wide stretch panels make it easy to pull on while keeping the foot secure and flexible all day, Red Wing's three-layer Waterproofing System keeps feet dry, and a subtle embroidery pattern gives it a clean, modern western look. Underneath, the Barnstormer rubber outsole delivers best-in-class oil, slip, chemical, and abrasion resistance.
