Great shoes

These are a great pair of sneakers that work both as casual sneakers and for dressier occasions. They are incredibly comfortable too.

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.
