I bought a pair of these shoes at a retail outlet for $65.00.  First I bought the size 10, but I felt like they were pretty tight.  So I returned them for a size 11, and the 11 seemed to big.  By then, I had already found these on-line for $54.00, so I felt like I over paid as well.

So I returned the shoe to the retail store, and took a chance on ordering them from Amazon.com in a size 10, hoping that they might fit better than the size 10 I got in the store.  And they did.  I've had them for a week, and I'm very happy. They are just little bigger than the one they had in the store.

At first they felt a little warm, but I got use to them pretty quick.

PS:  I also tried looking for these shoes in other stores and in other brands.  The Sanuk was superior and worth the extra money.  Don't waist your time if your looking for this style of shoe.  Get the Sanuk.
