Oh yeah I forgot about that. thats why I dont use them either :) Yeah i use roma brushing boots and they are great and cheap. tri-zone just came out with some new ones that are great too. I THINK that splint boots would work too... not sure though. Make sure the boot has firm protective covering on the insides of his legs. some are nothing more than fabric. although SMB protect a little bit and are shock absorbing... just what ever suits you and your horse, but I recommend the roma brushing boots.
