This type of shot is way more deceptive and has a much quicker release than a slap shot. Releasing a shot quickly and accurately with deception can make it very challenging for goalies. There is no need for a big wind up / load with a wrist shot. It can be taken with your feet moving or even while in full skating stride (which is what coaches look for). Players have more control over where the puck is going when taking a wrist shot. Plenty of repetition with proper technique can develop a better, quicker release. The energy is produced when you press down on the shaft of your stick with your power hand, followed by snapping or rotating your wrist in a forward motion which generates more spin on the puck. Locking your power arm towards your target will also allow you to generate more power and allow you to aim the puck more accurately.
