Finding the perfect cute AND comfy sandal: Birks or Rothy’s?

I (26F) am going to europe this summer with one bag and would like to bring 1 pair of sneakers and 1 pair of sandals. Bringing my Vejas as the sneakers. Looking for ideas on the sandals

Looking for sandals that I can do lots of walking in (like multiple miles) AND are also cute/trendy. I would like to be able to wear them while exploring the city, to the beach, or with a dress for nice dinners, etc.

People have recommended Birkenstocks a ton, which I am highly considering. This single-strap style [https://www.birkenstock.com/us/madrid-big-buckle-natural-leather-patent/madridbigbuckle-patent-naturalleatherpatent-0-eva-w_11568.html] has a slightly more polished look - would I be better off with the regular double-strap style [https://www.birkenstock.com/us/arizona-big-buckle-natural-leather-patent/arizonabigbuckle-patent-naturalleatherpatent-0-eva-w_11568.html#sz=48]? I also really like these Rothy’s sandals [https://rothys.com/products/womens-summer-sandal-golden-sun] because they look a bit nicer. Does anyone have experience with these? Would I be better off with Birks? Open to other suggestions!

I do struggle with over-pronation, so I need something with arch support! I have sworn by Tevas in the past but they are just not giving the right aesthetic for the Italian riviera lol. (We need versatility here! Comfort and style!)
