Product Description
Steel safety toe, waterproof, EH and puncture resistant — an 11-inch western pull-on work boot, CSA approved
The Red Wing Rio Flex is an 11-inch waterproof, western-style pull-on work boot built for long days in farming, ranching, oil and gas, and construction. It pairs a steel safety toe with electrical hazard (EH) protection, puncture resistance, and slip resistance to ASTM F2413-24 (I/C, EH, PR, SR), plus full CSA Grade 1 (ESR rated, PR) certification. 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 decorative 10-row western stitching with a dark brown leather upper brings the style. Underneath, the Barnstormer rubber outsole delivers best-in-class oil, slip, chemical, and abrasion resistance. It's resoleable for a long service life.
