I spent the last 2 months of my pregnancy in one of the hottest Michigan summers in history living in these shoes. My large dog needs a 3-4 mile walk every day and I could not bend over to tie my tennis shoes. Such wonderful support and they never slipped! These Birks were worth the price. I wore them every day in the house and outside. I'm not sure my poor dog would have stayed sane those two months had I not bought these shoes.
