I'm sure these cleats have been on my daughter's riding shoes since the day we bought them. She has used them for years now and I only noticed the odd design tonight when it prevented her from clipping into some Performance Campus pedals. She wore these same shoes yesterday with some actual Shimano pedals on her road bike, and they worked just fine. I did an image search for "SPD cleat" and didn't see any that looked like these do, with the extra metal tabs molded into the back of the cleat. Has anyone seen these before and know what they are meant for?

The unusual one is on the left, with a normal one on the right for comparison.

I read that thread and it seems it's a cleat that comes with off-brand ebay pedals. If you want to, read through that thread... A lot of good info on those cleats in there.

Are these the cleats that only go with the 858 pedals?

I think there's one Shimano SPD pedal that has its own cleat - that looks like the one.

These don't look like Shimano or Wellgo cleats. The arrows might indicate that they have float. Perhaps the fabricator protrusion to prevent the retention clip from locking the float?

Thanks for the info.

They are actually a set of 'single use' or 'event day' cleats. They are designed to be clipped in once and have to be destructively removed and discarded for safety reasons immediately after.
They are the same weight as regular cleats, and you can't tell the difference until you try to clip out for the first time. It is used as more of a motivational tool among racers, to put them in a 'do or die' mindset.
They were removed from the market after the gruesome death of the entire Lotto-Fuji squad in 1996.

Very funny but you really should include an emoticon to let the gullible know it's a joke. Anyway, I believe the first "clipless" pedals were made by Cinelli and intended just for track events. They did indeed require releasing by hand to remove your foot and would have been suicidal on the road.

My coach in the '80s had a set of pedals with a little lever he had to reach down and undo at every stoplight. At the same time I had some MKS (I think) pedals that released by turning the foot to a precise angle and wiggling the foot out. THe lever-pedals were probably better because they were consistent - my MKS ones left me lying on the road unable to clip out more than once.

Yeah, some of the early attempts at clipless pedal designs were pretty lame. It took a while for the industry to settle on the now universal heel-out release drill and some of the first ones had a tricky and inconsistant release technique.
