These shoes are very comfortable, but they are not very sturdy. I had several pairs, all of which I bought at the same time.  I estimate I wore each pair twice a week.  In less than a year, the soles had split apart and had holes in them.  I think that the rubber (or whatever the sole is made of) is probably too soft for regular use.  However, to be fair, it is probably also what makes them feel so comfortable.
