Sandals for lots of walking

Hi all, I'm heading to Europe next year and will be doing a lot of walking in warm weather. In my 20s I wore sandals with thin soles and no support, but now I'm in my early 30s those won't cut it with lots of walking.

Sandals seem to either look nice or feel nice, not a combination. I have no idea what to look for in them. Arch support? Ankle strap for stability? Any recommendations?

I'm generally a bit stingey but don't mind paying up to $200 if they're a classic look and will last forever. Preferably brown leather look. The closest I've found to a style I like: https://www.theathletesfoot.com.au/revere-miami-womens-cognac.html?srsltid=AfmBOorIDzHcC6Y7Uj0tRpdijlbQhos7pqHqOdAOAZTCqp4NSqcCIo3p
