The golf shank can cause the most embarrassing shot for both beginner and the experienced player.
The shank shot is a result of the ball hitting the part of the golf club where the shaft meets the clubface,called the socket,
When the ball hits this part of the club the ball shoots off at a ridiculous angle.

The main problem with the golf shanks is the almost mysterious way that a player can suddenly develop this affliction during a round and then consistently reproduce this most horrid of shots without any obvious logical explanation. For this reason just the mention of the word can send shivers down the spine of even the most experienced golfer.

So, what is the major cause of the golf shank? Well, invariably it is caused by an incorrect weight distribution during the swing, specifically too much of the players weight goes onto the toes during the downswing causing the ball to impact the club face off-center towards the socket of the club.

So how do I cure the golf shanks ? simple, just keep more weight on the heels during the swing.
If you look at most profesionals on t.v look at a side-on view of the swing and you can see how evenly the weight is distributed from front to back and how stable they look. Many amateurs lean forward towards the ball at address which is the reason their weight goes on to their toes during the swing.

If you want to permanently fix the golf shanks to get a good shoulder turn, At the top of your backswing your left shoulder needs to be over your right knee.This will maintain your swing arc and prevent you having to make the downswing adjustment of leaning onto your toes.
