I recently bought a pair of old mac G2s. They work well enough. I rode in them twice. I bought mine for the fronts.
To toughen up the soles try Keratex Hoof Hardener or Venice Turpentine. Don't get either on the frog.
I have a sore footed horse and have been searching for things to make him more comfortable.
Two things I came up with are Equi-cast and trying to create a "shoe" on the bottom of the foot with Vettec's adhere. I did the equicast last night for the first time. It turned out pretty well for my horse. We'll have to see how long it stays on and if it improves his comfort level.
I have pics of the equicast I can post later if you're interested. If you're not comfortable doing it yourself, I'd suggest your farrier do it for you.
