When it comes to casual footwear, I'm usually a bargain rack at Wal-Mart kind of guy. But this summer I left a pair of those cheap Croc looking knockoffs in my car and found one that had been in the sun a few days shrunk so it was about 3 sizes smaller than the other. This left me without something to slip on to walk out in the back yard or if I needed to run to town and didn't want to wear my tennis shoes. Caught these on a Lightning Deal and my wife encouraged me to give them a try.<br /><br />I normally wear a 1/2 size and as suggested ordered the full size DOWN from my normal 10 1/2. These lightweight shoes are comfortable and provide decent support for my relatively high arches, especially for a slip on casual shoe. The first time I wore them I went for a mile or so walk with my dogs without socks and found no discomfort or fatigue. The little knobbies that line the sole are different than regular shoes or sandals, but I adjusted to them just fine, The strap held them on place on my foot well and I didn't notice any of that heel slap action that normally drives me crazy with open backed shoes.
