I don't…but i don't ever know what brand or type of shoe. Today for example…i had been running in nike spiradons but they blew apart the other day…so i ran in some mizunos i had that i use for lifting…i went for a 6 mile or so run and my feet are killing me!!! the arch of my foot and inside of my ankle hurt a lot!! i guess i won't run in those again. i can hardly walk at the moment!!
