Dressage arena footing?

[petit fromage]

I would love to put a nicer footing in my indoor dressage arena. I saw an ad for something called Thorturf. Anyone have experience with that or how it is for dressage?
Thanks..

We have sand with a rubber/felt additive that is fantastic. We also added in MAG which draws all the moisture from that air into the footing so we never have to water and prevents frozen footing in the winter.

The footing in the arena I ride in is shredded leather. No dust, no clumping, no packing. Works for us.

I was just at a show that had the fibers in with the ring. I think they have also done this with the jumping ring at Rocking Horse. It is really nice.
