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 have been wearing these shoes for some time. I bought 4 more pairs a couple of months ago at a REEBOK store, (when I find something I like, I stock up!) and within one week out of the box the air chambers had cratered in the shoes. I got another pair out of the box and they only lasted about 10 days (3 wearings!) before the bottoms caved in. It's like stepping in a hole with every step. VERY POOR QUALITY! My previous ones all eventually went "flat" but it usually took 4 or 5 months. Not a week. I'm on the third pair and they're already losing their bounce.
I don't weigh 400 lbs, and I don't walk on cut glass and nails. So sad that quality control has just gone out the window.
