The Walk Ultra IV DMX Max - Wide 4E not only features DMX Max, our engineered cushioning system that moves air from heel to toe as you walk for “cloud-like” comfort, but also comes with width sizing so you know you'll get the best fit for your foot.
I've been wearing DMX Max shoes for about 15 years now. I'm a veteran of two back surgeries (with nerve damage in both legs) and the air cushioning system is FANTASTIC. It gives an extra shock absorber when walking. My feet, legs, hips and back are less fatigued. I highly recommend these to anyone who needs a little extra cush!
