When I’m in Paris, or any other city, I walk around all day long and into the evening. And even if my shoes are very comfortable, my feet can hurt and develop blisters. I learned a few years ago that carrying a friction block stick in my bag is how to avoid blisters. It reduces rubbing on your skin and makes your shoes much more comfortable. It’s certainly saved my feet a few times!
