got these new last week and I use them on my bent. I have a new well almost new maybe 100 miles on a set of 51 cleats on a set of m359 (think that is the number) and they were fine. but the 959s the cleats after 60 miles are starting to ge a bit sloppy. I can rock my feet around a bit they release both with outside and inside twists. though the cleats are only one way. have otehrs noticed this on 959's?
