Specifications

Where this boot fits

The I-90 EPX fits shop crews, drivers, and anyone tired of lacing up who still needs a real ASTM F2413 toe. The romeo cut slips on and off at the shop door, the waterproof upper handles wet ground, and the slip-resistant outsole grips shop floors. Pair it with a cushioned insole from our work boot insoles range and moisture-wicking work socks; seal the leather with our boot care and waterproofing products.

Fit, sizing, and metal-free advantage

The I-90 EPX runs true to size; because it is a slip-on, a snug fit matters, so avoid sizing up. It is the slip-on option in our composite toe boots range next to the lace-up Wolverine Overpass and the rugged Timberland PRO Boondock. Both Wolverine models use the same CarbonMAX toe covered in our steel toe vs composite toe guide.

Every metal-free boot on this page skips the steel cap, so it will not conduct cold into the toe box and it clears metal detectors at airports, courthouses, and secure facilities. If you are choosing between materials, our steel toe vs composite toe comparison and our how to choose safety boots guide walk through weight, conductivity, and compliance so you order the right cap the first time.

How it compares to its siblings
