The Walk Ultra IV DMX Max - Wide D 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 have worn the DMX Ultra for approximately 15 years. I love the air pockets on the bottom which provide a cushion for the bone spurs I have on the ball of my feet. Please don't ever stop making these shoes. I love them.
