Everyone in my family is different, I don't think there is one "right" answer.
I prefer Merrell, that is my brand. I have a pair of Siren Syncs (well, I get a new pair every year) and wear those with wicking socks. They are light weight and are pretty breathable so my feet don't get hot. I do bring a pair of sandals that I wear every few days.
Dh wears Keen sandals everyday.
Older dd (13) wears Merrell shoes like mine or Keens.
Younger dd (10) wears whatever tennies she likes that year (usually based on color - but she won't wear anything uncomfortable) this year I just bought her a pair of Asics. Or she will wear Chaco sandals.
