I'm on my second pair of Rocket 7's. They are not very durable, compared to off the shelf shoes. However, they are extremly light, and the first pair was extremely comfortable.

My first pair, wore through the sole where the cleat mounts. It's a known problem mounting speedplays directly on the CF sole. Now they add a thin stainless steel plate which is supposed to address the problem.

The heel pads also come off rather easily, and then you'll wear through the carbon unless you replace the pad immediately.

The "leather" on the upper is also rather thin, and can wear through. (I ground through one side of one in a crash). Although, while the uppers looked like hell after 4 seasons, they would still be functional had the sole not failed.

In spite of the durability issues, I bought the second pair because they are very comfortable. Unfortunat ely, the second pair doesn't fit me quite as well. Supposedly it was made to the same size as the first. However, I think Rocket7 has changed their process a bit. I believe the first pair were truely "custom" and the last was made to my foot, whereas the current shoe is made from one of a number of standard lasts.

Interstingly, the first shoes said "custom" on the shoes, the new ones don't. The Rocket7 website is less than clear whether they've changed their process, or just changed how they describe what you're getting

I sent them back to see if they can make the new ones fit a bit snugger. How well that works out is going to determine whether I'd consider them again or reccomend them again.
