We have done pads for most of the past 2 summers and they did help a lot, switched to shoes with 'heels' a few months ago, which helped also. Since we no longer ride on gravel roads we felt we could go without pads.
So, while the pads and the shoes with 'heels' helped, the farrier and vet felt if he did have a history of founder, the egg bars would be the trick. I am willing to try what ever I need to to keep my boy comfortable and sound, just wondered if anyone had used them, and if there was any down side to them?
( while I have thought about boots, I have had friends try them and they had almost as much fitting them as we all do fitting saddles!)
