blisters from walking

I guess its a good painful thing. On my way to a new life i have been exercising and have come to the conclusion that i have to get new walking shoes. After walking a mile and a half i have blister on the top part of my feet. So today at work i have on my slides because it is more comfortable than my heels today..  On a good night my preop is wednesday. Surgery is coming right around the corner.
