If there's any weakness in the Xpresso system (I'm an Xpresso 4 man, myself), it's that the cleats wear out pretty quickly. This is by design, though, as they're inexpensive, don't slip on hard surfaces, and don't include brass bits that damage flooring like hardwood and some stone.
These are great clips, easy to engage for the most part and are very stable off-bike. Since they're plastic, if you don't check your cleat wear often, you may find that your worn out cleats are affecting your connection to the pedal adversely. I only wish they had a better, less wasteful system to address the cleat wear more effectively. Perhaps a more durable (replaceable) rubber part? My left foot wears out much faster since I use that foot to support myself at stoplights. I've been through 4 sets of these at least. Each time, I discover that my faulty click-in is because I havn't checked the cleats... again.
It is a cleat that works with the pedals! I have not had a issue to date with this cleat. Works great with the Xpresso 4 pedals I have on my bike. Easy to engage and exit. Love the float feature on this setup. What more is there to say................works.
