REALLY GREAT FOR STRAIGHTENING
These really do straighten toes. The only problem I had is that they have to be somewhat tight to work but one night extreme pain woke me up. Turns out they were cutting off my circulation in my toes. So now I wear them for a couple hours watching tv every night - while I am awake!!  I wound have preferred to wear them at night while I sleep since I can't that is why only 4 stars instead of 5.
Rating: 4 stars
