Celso R.wrote a review of Speedplay Zero Aero Walkable Cleats on December 10, 2015
Familiarity: I've used it several times
I original used Look cleats but moved to Speedplay cleats about 3 yrs. ago. Of course, getting used to the cleat took some time, but I am so glad I did. The cleats themselves our an easy install once I realized I couldn't over-tighten the cleat screws. Over tightening the screws makes it impossible for the cleat mechanism to work with the pedal. In addition, I have specifically bought Speedplay ready shoes to take advantage of the very low stack height compared to the Looks I used to use. I really enjoy the fact that because the pedal itself is two sided, it's a very easy on and off. The cleat is low maintenance. They require a special lube every couple thousand miles. And because the cleat is covered with an aero cover at all times, they are easy to walk on and don't damage the cleat. The Zero cleat simply means that the cleat can be adjusted from 0 to 15 degrees of movement. The cleats I bought are actually my 3rd pair, as I bought an additional two pair of Speedplay ready shoes. Wearing Speedplay ready shoes require a protective shim. It protects the carbon of the shoe as the pedal is inserted into the cleat. They are a separate buy. When attaching the cleats to a non-Speedplay ready shoe, you must install a baseplate and additional shims, depending on the shoe. Those items are included in the cleat purchase. As a tip...when I went with the idea of switching to Speedplay cleats, I got on YouTube and found a lot of great information that helped me with the learning curve.
