Hi All, would appreciate input on boots for my Thoroughbred mare who has very thin-soled hoofs and every summer gets lame from moisture even though we have had very little rain this year. She is sometimes lame for months. She's on a supplement and I am treating the soles to toughen them up already. I am comparing the available boots: Easyboot, of which there are several varieties, Old Macs, Boas, etc. If anyone uses these and knows the pros and cons, would like your advice. Lark
