Swaying in my stance

I have noticed that I seem to sway in my stance. 
sometimes it seems I am back on my heels 
other time it seems I am swaying ever so slightly.

I have thought if I put a block under each heel it might help.
Is  this even legal or even a good idea.

Do others notice this and is there a fix.

Thanks all

Change the angle of your feet. Toes in if you tend to sway forward. Heels in if you to to sway back.

One thing I am doing to help my stance is footwear.  Currently breaking in a pair of 8" boots for this season.  Zins mentioned footwear briefly at the clinic.  Bought a pair of non-insulated gore-tex Red Wings.

With your gun unboxed and safe, magazines loaded, get your feet positioned and lock into your stance, make sure it's consistent to the bench every time.  Tell yourself you are locked in and ready to go and check it off the list, stop thinking about it. Place the gun in your shooting hand and get your grip set.....and the list goes on.  The important thing is to be consistent in everything you do to get set before the shot or string, then check each basic item off.  Stop thinking about them once they are checked off. If you keep telling yourself that you're swaying then you're going to sway, and you won't be thinking about the shot.  Your mind will be preoccupied away from hitting an x.

Thanks all I will let you know how it goes

The suggestion to turn toes inward is a good one, and one that I usually recommend.

Furthermore, one of the things that I talk about a lot when I teach clinics is that you actually have to practice standing still.

The thing that I see most in people shooting at the Marksman/Sharpshooter/Expert level (and I watch a bunch) is that they do not. stand. still.

Just.

Stand.

Still.

For a minute. 60 seconds. That's all I ask.

Don't tap your feet. Don't chew your fingernails. Don't check your phone for text messages.

You can do this anywhere - in line at lunch, or at the bank, or when you get home from work.

But you have to practice it.

Stand still.

KCKral's advice is spot-on - you need to be able to stand still, reliably, and then shift that function over to the subconscious.

Do it for 60 seconds at the start of every training session, then do it for 60 seconds at the end of every training session. It will pay huge dividends.
