I am starting hospital rotations soon, and I'm going to be on my feet all day, running around. I was at the mall the other day, and stopped in the Geox store, and they had a bunch of shoes for 50% off, so I bought a couple pairs. They seem to be very comfortable, but does anyone have any experience with them? Are they the types of shoes that seems comfy in the stores, but once I put them on and wear them, they'll give me blisters? Or are they really just comfortable shoes?
