I rode Speedplay X-2s for years prior to trying Zeros and NEVER had problems clipping in (unless they got caked in mud, like on the C&O Towpath on Bike Virginia one year!) Totally different situation with the Speedplay Zeros for me. They gave me big problems clipping in, even trying all the tips mentioned on this thread. I really liked them once I got clipped in b/c the X-2s gave me more float than I needed and robbed me of some power.
