Wear Wolverine® I-90 Rush Waterproof Work Boots for fatigue-fighting comfort. EPX Anti-fatigue insole uses low-density foam to provide cushioning from heel to toe, while the high-density base layer evenly distributes your weight for increased stability. The insole flexes with each step thanks to the ribbed design. And its honeycomb heel absorbs impact and returns energy with each step. Even the outsole is designed to out outlast, thanks to increased abrasion resistance. All this, in a stylish design that easily transitions from work to casual wear.
