This my second pair, bought to replace first pair when needed.  I have bought shoes that when I wanted to replace, they were no longer made or design change that I could not wear them.  My original pair is wearing through the rubber soles at the heels but that is due to my being a heel striker walker.  Outside and inside have held up extremely well as these are worn everyday on laminate flooring.  I needed something to replace the cushion formerly provided by carpet day to day. These did the trick.  Only improvement I would ask for was a little higher arch.  That is why the 4 star.
