I don't want to step into the argument so far but will add 2 things.
1. I've used the Orb2 pedals, which are dimensionally very similar to these, for years and have never had an issue with the size of the pedal or cleat.
2. While I don't have any issue with the size, I do see a potential issue for some of the more "wild" riders. It's the same issue the first gen Orb suffered from. The release motion of the cleat is one where you slide your foot inward toward the crank and pull up. Some guys really throw the bike side to side in a sprint. When you do this you lean the bike and continue to pull straight up on the pedal, this makes your foot pull inward toward the crank and up, the same as the cleat release motion. I asked them about this when I was in Vegas and got a semi-dismissive reply. Basically because a couple of riders have not had a problem with this they are willing to apply that to the whole group. The problem is the test riders are veterans of the sport, and veterans tend to have, for the lack of a better phrase, cleaner style. Many (but not all) aren't so wild with the bike. However as many companies learn, the general public doesn't always behave the same as a select group of test riders. The big question will be, are there any riders out there that during an effort, lean their bikes to an angle where pulling up moves the inner sleeve enough to cause a release. Granted it's not a sprinters pedal and this may not be a problem, but the potential for one is there.
Regardless, I look forward to getting and testing a set of these pedals.
Yep, It's (above) a potential.
I pulled out of the ORB's doing exactly that motion.
And it wasn't a sprint... It was climbing where someone attacked and I made a big effort out of the saddle to go too. Big acceleration is what it is and doesn't care it the terrain is flat or tilting up.
These have that same motion.
