That's when the toss some carbon fibers into the mix and then mold as usual (injection mold?). It's supposed to add stiffness and some strength. It's possible, I suppose, but I've never seen data (and honestly, I've never looked).

They've been at it since 1993 and have global distribution. Chances are the shoes are pretty good as long as they fit your feet.
