This shoe is very uncomfortable if worn during an 8 hour work shift. Not the cushioning, which I had to put gel inserts in but at the eyelet post where the boot meets your ankle. I bought this boot thinking they make tennis shoes so know a thing or two about comfort. My last work boots had worn out and thought I would try this. This was $20 cheaper so figured I had nothing to loose. The side zipper doesn't work as well also but since I gave up wearing these can't tell if that would have been a problem after time.
