I have one of these (in black), and so far so good, only used on the trainer so far:
https://www.aliexpress.com/item/1005006735996295.htmlBut: I'm brand new to Speedplay, so take what I say with a pinch of salt. I recently got a pair of Comp pedals second-hand at a bargain - I'm intending to try them on my commuter bike. The pedals came with a pair of barely used original grey light-tension cleats, but those cleats made a creaking noise and were too easy to unclip. So I purchased the "Alltoo" branded cleats from the link above. At first, they were really hard to clip in to, but apparently that's true of the original standard tension cleats too. I've broken them in now with some drip-on wax and lots of clipping in and out. And while riding on the trainer they feel really solid - none of the creaking of the grey cleats.
Some differences:
The walkable covers are softer than the originals, and easier to put on and take off. Maybe they'll fall off more easily? But replacements are ~US$3 on AliExpress.
The float adjustment grub screws use an Allen key for adjustment, instead of a tiny Philips head screwdriver - a win for the cheap ones! The grub screws make a squeaking sound when adjusting though, which doesn't feel/sound very premium.
Oh, and the aftermarket cleats don't come with the 3-to-4 bolt adapter plates, but those are also available from AliExpress.
