When I first put them on, they seemed stiff, but the longer I wore them, the softer they became.  They fit true to size. I have Plantar Fascitis and these provided excellent support and after being on my feet for most of the day with these - my feet did not hurt.  Highly recommend these - plus I got a great deal on Amazon - the day I bought them they were specially priced at $44.95!!  Very happy with this purchase.
