Comfort is a must, especially when you are on your feet for long periods at a time. These Wolverine wellington boots feature the all-exclusive Fatigue-Fighting EPX in the footbed of the boots. This technology cushions and flexes with all your foot movements. It returns energy back to your feet to ensure they stay fresh and comforted throughout the whole day. These wellington boots also feature a nylon shank to bring comfort even closer to the foot for lighter weight support.
