I have had a few pair of Chrome shoes that I have always found comfortable but this is the first pair with the SPD compatibility. I love them for the extra power they give me on my single speed bikes that I ride around town. The flat sole makes it easy to wear them anywhere as opposed to a regular road or mountain bike shoe. They are more stiff than the other Chromes I've had, but that makes the pedaling that much more comfortable. I would add that I had to go up a 12 size to make them fit me properly. I made the change and now I'll swear by them.
