I just got my CTX tapes in the mail yesterday and started with Step & Intervals. During the workout, I noticed that my toes were going numb - kind of tingly all over. Does anyone have a recommendation as to what brand of sneaker works best for them??? I know my current ones are large enough, as I generally wear a size 9, and these are a size 10, so I'm thinking maybe I need to try a new brand. Any advice is greatly appreciated!!! Thanks!!!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
