I bought these because of all the claims they would help with various foot problems. My feet apparently are not made for these and I found the shoes to constantly shift, causing my foot to be partially off on the inside heel section. When the shoe shifts that creates a very uncomfortable situation, so I sent them back. I also have a different slip-on version of these in a larger men's size. They don't do the shifting, but are far too long and are not comfortable. I think these are probably better for people with high arches and no major pronation.
