Huge Vionic fan here. Have several pairs of sandals, slippers, and sneakers.  Vionic has been a lifesaver this past year. My rheumatoid arthritis medications have given out on me after many years. Been trying out one medication after another without any luck. The past 3 months, my hands have gotten really bad. I struggle to do simple things like hold a toothbrush or tie my shoes...hence my need for slip-on sneakers. Unfortunately, these fit quite differently from any other Vionics I've owned. They aren't deep enough, so the shoes are extra tight. The mesh isn't stretchy, so the top of the shoe presses down tightly on the entire top surface of your foot...it's painful.
