I got these shoes for walking exercise, so I am somewhat picky on my expectations. I recently purchased a pair of New Balance walkers for about the same price, from Amazon of course. Those are great for walking. These Propets however, produce the noise in the title of this review, very loudly/noticeably at that, first the noise from the heel, then the same thing from the toe. It drives me crazy. I have never had shoes that did this. You may not mind the ker plop - if you don't, these could be great - they appear to be well constructed (perhaps too well!!), but it prevents me from wearing them.
