I'm planning on visiting a variety of destinations (Iceland, Ireland, France, Belgium) this summer (June), and want a pair of shoes that will basically do it all. I'm considering my Ahnu walking shoes - but they're leather and I'm worried about hot feet. My second pair of shoes that I'm planning on bringing is a pair of strappy Teva's that are super comfortable for walking in, as well. Between these two pairs, will I be ok? (I have some light Sketcher Bob's, but those don't seem substantial enough) Any insights would be welcomed and helpful! Thanks!
