The only Miz Mooz sandals I own are the 'flaire'. I love them so much I have them in all the colors!
The TSV style doesn't interest me at all...so an easy pass. As for arch support or any other feet issues, thankfully I have none.
I walk barefoot w/o socks around the house and outside around our home....done that all my life.
The only exceptions are when I am mowing our yards I'll wear an old pair of sneakers and when I'm shoveling snow I'll wear a pair of workboots with the ice cleats.. Those are really the only times...when I absolutely have to for protection.
The only time I wear boots/shoes/sandals is when I go somewhere.
