Runs big

I bought my usual size and they were swimming on my feet - like they would flop off when I walked. Cute style but will have to order a 1/2 size smaller than I wear

I love Vivivia shoes

Super comfy suede black slip ons. I got a true to size in this style. Great arch support and traction on the soles.

A Little Too Big

I have been wearing a size 6.5 in this brand for years. I have gone through at least five pairs of size 6.5 Vionic flats. I bought a size 6.5 in this style. I had to buy pads for my heals for these to fit. They are about 1/4th of a size too large. Once I put in the heal pads they worked perfectly. They remain a very comfortable brand of flats.
