The Walk Ultra IV DMX Max - Wide 2E 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 walk along city streets about 2 miles per day, 4 days a week. The last 4 pairs of DMX MAX walking shoes that I bought have fallen apart after a few months. There is a serious quality control issue. The shoes are very comfortable when new, but don't last. The air bladders are the first to go, then the uppers come about from the bottoms. Poor quality.
Buying them for $20 a pair at the factory outlet made it tolerable, but they are now dramatically over-priced. They're really worth about $20 per pair.
