The shoes were a choice I made in replacement of a defective pair and I am delighted in the customer service in helping me get a replacement pair. I bought two pairs of Ziglites and one of them completely fell apart. When I called the store for replacement, I was greeted nicely and did receive a replacement shoe which I picked from the online store and chose the Flex shoe. It is comforting to walk in however, if feels as thou it has little support on the bottom on my foot and after wearing them for an hour or so begin to feel pressure squeezing my foot. Perhaps could have went with a wider shoe, I use them for walking and exercise class, so I am hoping that will not cause issues with my feet. I do switch out to both the ziglites and the flex and feel more support with the ziglite.
