I LOVE these sandals... they are so comfortable!  In Vionic sandals I have to size down, normally wear 7.5, but got 7's and they are perfect!  The footbed is very soft and arch is fantastic.  Even though the toe strap isn't adjustable it doesn't matter... the fit is so great, very easy to walk in.  I've only worn them around the house as it's too cold outside, but I can tell that they will work, and just ordered another pair in black!  I'm ready for warm weather... and happy feet!
