FlowBoot has a new version of its performance boot for rear legs. It closes in the front, and fits so perfect that is snaps on. You can actually see the shape of leg, ankle, and tendons inside the boot. Much easier to wrap. Sleeker for less interference, lighter in weight, and we added an outer skin for durability. Conceptually the same just better made and designed to last. This rear boot fits 80% of all horses from medium to large in sizing. When racing it is ideal to put on with a vet wrap giving you options of colors. With vet wraps your horse will look super sharp. When done use a letter opener down the front for quick removal. When training the regular wrap works fine and also can be used to race in.
