I have three pair of Propets. They aren't beautiful, but they are stable, which is what I look for most, and they come in pretty colors. They are also more reasonably priced than many other orthopedic brands like Drew, which are not better quality.
I wear their dress shoes. If you are looking for a stable sandal, nothing beats Finn Comfort, but they are four times the price. Worth it since I would never be able to walk in sandals otherwise. They are an investment, last forever, thick leather made in Germany. I have a blue pair and a silver pair that are pretty dressy for orthopedic stability shoes.

I have CMT, can neither feel my feet nor move my toes, so shoes have to be very secure or I can walk right out of them and never notice. Never wore flip-flops in my life.
