yes, they do work

i ran 7 miles saturday morning before work, with ahna, who did great! i wore my new training shoes and they are great. i then, put on my mbt's (yep, the dorky ones) and wore them the remainder of the day. i can definitly tell the difference. they work you the entire time you stand on them. i am wearing them again today. always looking for a good workout! hope to lose this extra weight i put on over the summer soon. should with this workout!
