Vionic sandals are the only ones I wear. Great arch support. When I got my very first pair, it did feel weird walking on them the first day or so, but I quickly noticed my feet didn't hurt at the end of the day. That was five years and many pairs ago. For me, I can easily get a few summer seasons out of each pair before they start looking worn.
Some styles have more arch support than others, I would say this particular style leans towards less support, but it is still a comfortable shoe that I can wear all day. I have narrow feet and the adjustable straps make for a perfect fit. Also, with the Vionic shoes, I found that they are pretty size consistent.
