Actually, my initial choice was Vivo, but when I went to the shop and actually tried them on, I couldn't find one single model that fit. They were extremely tight on the top of my feet, literally couldn't tie them up. That's when the girl at the shop recommended Xero to me. They fit like a glove.

Oh bummer. I think they marry quality and aesthetic better than most other barefoot shoes on the market but Xeros are great too. I love the pair I have.
