Anyone use this? Sounds like a good concept, but I don’t know anyone with these. Unless they are not telling me!
several of us are testing them right now. we’ll write about it.
I’ve used them for years. I use them mostly for fixing lower leg length difference but do use one extra shim on one side for pronation to keep my knee tracking straight.
They do wear a bit with speedplay pedals since the pedal is in direct contact in the center.
I use them and I have for years; they make all the difference in the world, and I couldn’t ride without them. These are–IMHO–a solution that finally addresses the real source of the knee problems that often accompany the use of clipless pedals. (Search my other posts if you’d like details about my setup–or ask me and I’ll elaborate.)
I don’t understand why they changed the name from “big meat” wedges. Searching for big meat results in many more search engines results. 
They were obviously going after the vegetarian/vegan cycling market!
