I bought these for the sake of arch support since my doc asked me to stop wearing flip-flops. I think they are sturdy and do provide good arch support. I wear these everyday to the pool and the material is definitely water proof. As for sizing, I usually wear an 8-8.5 in shoes and the polysorb 8s fit me just right. As for looks, they look like a beach slipper, nothing fancy, but at least they do the job.
