I have Tarsal Tunnel Syndrome & wear orthotics in my shoes.  I have joined a gym which offers water aerobics & other water exercises & wanted a shoe other than a flimsy water shoe.  My first class is December 3rd, 2012, so I went to 2 local Big Box sporting goods stores.  The clerk in the shoe department at Sports Authority said the only option at this time of year is the water shoe.  I went to Dicks, and the sales clerk said they didn't have any in the store.  He told me the water shoe would not give me the support I needed.  He told me to check on-line and not to let anyone talk me into getting a sneaker & wearing it in the water.  He named a several brands who make shoes designed to wear in the water for things like water aerobics.  I was delighted when I saw these on Amazon.  One of the reviewer said they tend to run small, I normally wear a size 8 or 8.5 shoe.  I was going to order a 9 until I saw that review.  They arrived today & WOW the size 8 fits me perfectly.  They are so lightweight and cute I really can't wait until my class on Monday!  A friend who is taking the same class is going to be green with envy.  LOL
