I find sandels with memory foam insoles very helpful in water areas. I have purchased Sheckers brand good. I get a sandel that has a wrap front over the toes and bottom of the foot with a strap that goes around the back of the foot/ ankle. I also try to find leather materials since they tend to fit more secure and hold up well in pool and lake/ocean waters. There are some other brands such as Columbia and New Balance that are nice. However, you need to try them on at the store otherwise you could end up in a mailing issue if you buy and have to return them due to a bad fit. Some times at drug stores that carry diabetic shoes/sandels you might find a good feel and fit. Ask the pharmacy for help here.
