Going to Europe, suggestions for comfortable, not-ugly walking shoes that will last?

As title indicates, I’m going to Europe with my spouse. I’d like to avoid wearing workout shoes while we walk around as tourists. What are some suggestions for some relatively fashionable shoes (for men and women) that will last for a long time. Preferably, something we can walk in all day that do not scream “American”?

Edit: 1. Thank you for the replies! I will check them out.

1. To clarify, we are going to surrounding areas of London and Paris. I made it a general request since we will go on multiple trips.

2. Yes I know shoes are not the only thing that will out me as an American. I just like to blend in AND not have my feet hurt.
