Do these work with shimano cleats? I read that some of the onirii pedals will not work with non-onirii cleats without lateral play, and onirii doesn't sell their own cleats iirc 
I'm a heavy rider (104kg with shoes, helmet, etc) and I'm 4 months (and around 1000km) onto my onirii pedals (PD-06 with extended Ti axle) with zero problems.
I'm using it with the original shimano cleats that came with my PD-R540. I had to replace the shimano pedals after about 2300km, because it developed some play (it was getting worse after each ride).
