Leg protection?

I'm not sure if this is exactly where this should be but hopefully it's close enough. =)

So I was wondering if I should go find Lacey some sort of leg protective gear since I've noticed that she seems to have a predisposition towards hitting her hind legs (pretty much in her fetlock/pastern area) against each other (or something because sometimes she's ended up with scrapes on the front of her pasterns). She just got shoes on (her hooves were just cracking and getting chunks taken out like crazy) and so I'm kinda wondering if I should get her something in case the shoes make her more dangerous to herself...

She has pretty nice straight hind legs so I'm not really sure why she hits herself but she evidently does....

Also, if you recommend I get her a little something something, what brand should I get? What type of shin-dig?

I've used SMB's before and liked how they worked, but Lacey seems to hit herself more in the pastern and I'm not really sure something that starts at the fetlock is going to do much help, yknow?

Also, what size do you figure she'll be? She's an Arab so she's rather light boned but more old school bone wise than the current super tiny Arab bone-liness... I was thinking maybe a medium?

You could try some leg wraps. They are great for doing ground work.

If your looking for boots to put on her while turnout, because you said that is where it occurs most often, I would get a pair of fetlock boots.

I use the Sports Medicine Boots Elites. They are quick and easy to put on.
I have used polo wraps, but they MUST be put on properly.

I had one horse that I had to add bell boots on the back due to the way he would sometimes clip his hind feet to together or step on himself

If it is for turn out, they make hind fetlock boots that are rubber and like a bell boot material. I am pretty sure that you can have them on 24/7
