I am sure this was discussed somewhere! I tried searching with no luck. I have heard of placing an icecube against the foot and then quickly taking it away. This causes the foot to retract enough to get a credit card under it to gently pry it from the rock. I am picking one up on Sunday and want to make sure it doesn't get damaged while removing it from the rock it is attached to. If this is discussed in another thread please link me to it.
