My SPDs sometimes "lock" even whit the tension adjusted. For example, if I put my full weight on a pedal.. say for like a dismount on the fly, I can feel my foot REALLY lock into the pedal and it takes a lot of effort to unlock-

Not good in traffic nor a cyclocross race.

I swear that these pedals are for people who must have stiff ankels or something. My ankle just twists and there is only so much twisting I can do.

I am having a lot of second thoughts about doing this cyclocross race. Its my first one and its getting to late for me to screw around with pedals and I have already slammed my kneecaps too many time. When I get it right and my pedals are okay, I can get off the bike- not fast (I am not expecting to win here, just finish) but I can do it.

But when I lock in..., =( I get hurt.
