text: I ordered these Adidas Athletic Voloomix sandals from Amazon and the Voloomix Sleek from a third party seller.<br /><br />There was a significant size difference. I ordered both pairs in a woman's size 8. The athletic pair were almost 1 1/2 too big (They looked like they were men's). I decided to keep them, but if you're looking for a sandal true to size I reccomend getting the Voloomix Sleek.
