Chacos became my new favorite sandal this year. I have three pairs of them.  I really like the Z strap style with the wider straps.  The footbed is so supportive. The rugged soles can go anywhere. I love that they are adjustable, so I can wear them snuggly or loosely. They are great for all-day wear on your feet.

I normally wear an 8 in most shoes but sometimes a 7.5. I ordered a 7 after tying this size on in a local store. I have a pair of Chacos that are size 8. They fit, but the arch support is slightly off on the bottom of my foot. and this is annoying. Even though the 7s are shorter, the footbed fits me better. I would recommend that you try these on in a store before purchasing online to make sure you get the best size for you, especially if you go between sizes in different brands of shoes. You should also try different styles on to see which ones you like best, the open toe or the ones with the toe loop, the multi-strap or the single wider Z strap, the classic footbed or the cloud footbed that it a bit springier. This particular style  (Z/1 Yampa) have more of classic footbed that is not as cushioned as the newer cloud footbed, but the soles are very flexible and easy to walk with. Again, you will want to try them on in the store to see what you prefer. You can find more of a variety of colors and styles online, which is why I decided not to buy in the store.  These are great sandals. I plan to use them for years to come.
