I have a pair of black, ASB's for sale. They have dirt on the outside, nothing a wet rag couldn't take off. I used them on one of my Walker mares a few times (the dirt), but they were too big so I got different ones. They are black, size LARGE. Asking $40 including shipping.
All Sport Horse Boots - Dover Saddlery.
I got them for $55 dollars at a tack shop. Thanks for looking
