Couldn´t have said it any better!
@Lalof wear whatever you feel comfortable in!! Sneakers are widely worn in Europe and popular with all ages. And you can´t avoid to be identified as a tourist. I can´t either as a German being on vacation in Italy... Why, we all dress differently when we are on vacation. We don´t go on the street in our business/office wear when we´re on vacation. We don´t wear shorts either when we go to work...
Especially cobble stones can be tricky so do wear comfortable footwear!!
