Donna,
The take on the aluminum shoes is 1) they aren't as strong or supportive
to the heel portion of the hoof as a steel shoe. 2)They also don't last
as long.
These aluminum shoes weren't designed to give a horse protection for
25-50-100 miles of continuous pounding. They are racing shoes for
relatively short distances.
As I can guess, you are in Florida. So am I. You need a shoe that will
give some support for the heel and kind of have a snoeshoe effect in the
deep sand. I started my rookie year off in steel rim shoes and after our
first race switched to alum polo plates...no support at all. Then we did
Lake City, which was half under water and that's where we noticed a
lamness starting.
My farrier and vet made a supportive shoe to help support his heels in
front by starting with a rim shoe and adding a straight bar across the
back of the heel..really a modified eggbar. The straight bar kept the
bar under the heel bulbs and not sticking out so there would be less
chance of overstepping and pulling the shoe off.
The shoes have worked well in his recovery. We've gone back to a rim
shoe for the summer.
My personal experience in our sand has been. Stay away from aluminum
shoes. They don't give the support we distance riders need.
