Both boots are at the barn...so I'm not sure which ones I use. We leave all our stuff out there in case anyone else needs them. I think these boots have a different use than the ones you're describing. You wouldn't keep these on overnight, and they would need to be water proof, since they're holding in the water. But I stick my finger in the top and check the temperature. Once it's cool, I empty it all out and either refill or walk the horse or pack the hoof.

The first boot I used was sort of a molded plastic black and blue, but it was difficult to slip on. One of hte other girls had a larger neoprene boot that was more soft and moldable and opened further down so I could easily get her hoof in it. It had velcro straps to hold it around the coronary band. I think both are in pretty much all the catalogs. I also used a rubber feed tub and small bucket, but my horse didn't like not feeling steady on them. With the boot, she could shift around and stamp in frustration, and it wasn't going anywhere.

I highly recommend animalintex drawing poultice pads...In a last ditch scenario, I was able to soak them in water, heat them up in the microwave and apply them to the sole and the coronary band, then apply gauze and electrical tape.

Epsom salt drawing salves with salicilic acid (asprin) also give the horse a little relief.

But they always seemed to pop when I put on icthammol...could just be the timing though as I was always getting desperate when I used icthammol!
