A thick green canvas poultice with a black durable sole, these really are a must in any first aid kit. complete with a velcro quick closure tape, these are excellent as a temporary cover over a normal poutice bandages to keep the foot clean and dry.
I have used these on every horse that has had a foot problem, and although designed for indoor/stable use, I have successfully used them in a dry field, enabling me to give them turnout when they would otherwise be confined to a stable - this in turn helps to reduce leg swelling. Also, a great help with a horse that is used to 24 hour turnout!
