Tiffany - my feet go numb as well - if I'm running or on the elliptical.
My sister tells me to make sure that my shoes aren't tied too tight. She's such a smarty! So I've told her I'm not cutting the circulation off - what other advice does she have.
She said the same as Maleficient said - go and make sure you have properly fitting shoes. Which atm I have not done - no good shoe stores around here.
