I have a couple of questions for you veteran t-tappers out there. I have been contacted by the trainer in my area to attended the seminar in Tampa. I am really considering it but since I am fairly new to t-tapp I am concerned if I can keep up for four days. I am also getting ready to order the meta trek shoes. Do they run true to size and is it my understanding that with these shoes when you do your workout your butt is tuck for you and you just need to worry about klt's? Thanks ladies.
