I bought 3 pairs. I wear them to work, I wear them 12 hours a day, 7 days a week. I got "RAUS" out of the shoe. The sole is separate from the core of the shoe. I was like wow so I bought a few more and more. The same thing happened. You must return to the drawing board. I've been buying NUNN Busch since 2008. Some of the shoes I bought 14 years ago are still in use, but the ones I bought and wore for less than a month have melted into my feet. I mean, who cares more about quality or brand…
