The only downside to Zeroes (I have them on two bikes) is that there are very few 4 bolt shoes out there. So you have to use 3 bolt adapters, which are included. Net of this is that getting your cleat position dialed in can be a pain in the ass.
Also, they really aren't walkable unless you put covers on them. That may not matter much, but it is a pain if you're sliding around a convenience store trying to buy something in the middle of an all day ride.
All that being said, I'm wouldn't change pedals even if it were free.
