So very happy for you MiffyBunny and would love it if you could share how you achieved success. I read something ( I think it was in the Steve o book) about feeling as though there's a wrinkled sock inside your shoe. As for knees, they are not my problem, but crawling on hard cold floors to get around does not make them happy, I must say. They prefer carpet! It is so nice to see the people such as yourself who have had success return to the forum give an encouragement. It means a lot to those still struggling.
