These shoes are advertised to help with people whose toes go numb during exercise, so that's why I jumped (no pun intended) at the opportunity to buy them. I've had this problem in the past, and the issue was slowly creeping back in my old New Balance shoes.  I wore these shoes for the first time for a Zumba workout last night. And my toes immediately went to sleep for the entire hour-long workout.  It was the most painful experience I have ever had exercising; by the end of the workout I felt like needles were poking my toes.

I am going to try them out again using SuperFeet inserts, but this is unfortunate, because the padding that comes with the shoe is VERY comfortable - feels like I'm walking on a cloud. In order to use the inserts I'll need to take the padding out.  And spend a great deal more money to modify an already expensive shoe that was supposed to take care of that problem for me.

The shoe itself fits wonderfully, and I am better able to jump and pivot than in my previous New Balance shoes.  But if my toes keep going to sleep, I will have to figure out a way to return them.
