These shoes are very comfortable.  It's like walking on air.  If they do the "shaping" business, I'm not so sure but it does encourage one to walk a lot so I guess that's good.  Heed the advise of other reviewers and get this pair 1/2 to 1 size bigger.  I got just my normal size of 6M but it was a bit tight.  But after loosening the laces quite a lot, I still fit in it.  I would buy a size bigger the next time though.
