I have Planter Faciaitis and need to wear shoes with good support all the time.  I do water aerobics and the regular water shoes I had been wearing were not working at all.  I bought the Teva's after much research and was amazed!  The first time I wore them in the water aerobics class was the first time I did not have to limp to the dressing room after class!  I was able to do all the workouts with absolutely no foot pain at all.  From now on Teva is the brand I will buy for all of my athletic shoes.
