Runs much bigger than expected
Size: 8.5, Color: White
Nice design and looks good, but sizing is completely off. Ordered 8.5 (usual size) and it fits much larger, closer to a 9.5. Already did two exchanges and both had the same issue. Not reliable sizing.

Makes a lot of noise when walking
Size: 10, Color: Black
I wore this for the first time, and it kept making swushing noises. It was extremely embarrassing to walk around on them. However they are comfortable.
