These are just terrible. I wear an 8 1/2 and recently bought expensive shoes ( SAS) and some inexpensive shoes ( Target ) and know my size is correct. These are made in China and marked 8 1/2-probably were a 7 1/2. The sole is flat-the material is ( can't describe it ) not even a tennis shoe material-more like plain old rubber that you would see on cheap flip flops. If you take out the insole there is cardboard. I know I could have returned them for a refund-however we are having a clothes/shoes drive for the homeless where I work so I dumped them there. In addition to being small they are also very narrow. This may be one of the first negative reviews I have ever written on Amazon.
