Parry is really more like a guard break.
Parries can be cancelled and have a cooldown of 1 second. Cooldown isn't activated until you hear the sound of a successful parry.
They can be a bit hard and require patient timing, but the effect is a large knock-back and allows crits on hit enemies. Or just use the Alt key.
You can't run and block at the same time, only walk.
