Overview
Built for demanding workdays, this mid-height waterproof boot is designed to keep feet dry while supporting long hours on the job. It combines a breathable waterproof membrane, PFC-free Durable Water Repellent, and a moisture-wicking lining with a removable metatomical insole for arch support and a more natural fit. The KEEN.ReGEN midsole is made to help reduce fatigue through repeated shifts, while the oil- and slip-resistant rubber outsole is intended for traction on slick, wet surfaces. Added details like the wraparound toe guard, stability shank, heel support, and electrical hazard rating make it a practical choice for tough, active environments.

Considerations & Trade-offs
- Mid-height design offers less lower-leg coverage than a taller boot, so it may not be the right choice when you want extra protection above the ankle.
- The waterproof membrane and PFC-free DWR are aimed at dry wear, but that also means the boot is built around weather protection rather than maximum breathability in hot conditions.
- The removable metatomical insole and KEEN.ReGEN midsole focus on comfort and support, but fit and feel can be personal, so they may not suit every foot shape or preference.
- The oil/slip-resistant outsole and electrical hazard rating add useful worksite protection, but they do not replace task-specific safety footwear requirements where different standards are needed.
