I am 5 months pregnant and have some low back pain and SI joint issues.  I need a hard soled shoe to walk around the house in and thought with the great reviews this product would be perfect.  Unfortunately, these just never felt comfortable.  Also, I really dislike the style - too old lady-ish.  Given their great return policy, I still wanted to give them a try since other reviews said they helped with their pain issues.  I gave them a fair shot and ultimately decided against them.  I've returned them and will look for something else.
