Hi Cathe, I just purchased a pair of SpringBoost Performance Training Shoes, I don't know if you ever heard of them but I saw them on a website and in a book and I thought I'd give them a try. They are based on the dorsiflexion technology, they have an insole of 1 degree and when you get used to that you take that out and use the 3 degree insole and then when you get real brave you use the 5 degree insole. I worked out with them today just with the 1 degree, I must say it does feel wierd at first. Just wanted to get your opinion on them and to see if you ever heard of them. Thanks hope to hear from you soon. Take care, Pam
