two that I have heard mentioned are Epona and Easywalkers...I know I read a testimonial from one of the ladies here on the Easywalker site..they sounded very interesting. I am still struggling with the "to shoe or not to shoe" dilema...if I decide to go with a shoe, I want to find out a little more about these as they sound like they MAY be an option. Oh, how I wish Boom could talk..lol
