I was told by a podiatrist several years ago (when I weighed about 250 pounds) to wear nothing but New Balance Running Shoes and Birkenstocks (any style), and that was all I wore for years.
When Vionics (Dr. Weil, Orthoheels) came to QVC, I bought a couple pair of the Sandals, and liked them.
ON MY FOOT, the arch support felt a little higher and less secure than in the Birks, because in the sandal, there was more "slip" as I took each step.
I continued to wear the sandals for dressy events when I didn't have to stand or walk very long or very far.
Later, I bought real leather suede loafers and liked them so much I bought several colors. THAT STYLE, which I think was in the Dr Weil era, had much less arch support, but I've worn them for years and they've held up very well.
Your foot cannot be the same as my foot. I've lost a great deal of weight, get more exercise, and in general am leading a different lifestyle than I was in my Birkenstock days.
But short answer, based subjectively on my own experiences s, you should definitely TRY a Vionics style and not buy bless you can return.
GOOD LCK- nothing worse than living with sore feet!
