I just got a pair of Speedplay Frogs. For those of you who have these, when you clip in, do they make an audible "snap"? Do you push down into them, or rotate your foot and sort of wiggle in from the side?

All I've been able to do so far is slide my foot into them from the side, sort of reversing the clip out motion.

And there's absolutely no tension before clipping out. The foot just falls out from the side, which I actually like. But is this normal?

Thanks.
Amy
