having measured my mare 4 boots it seems the only type that accomadates her hoof shape is the boa boots..hav used these before on my gelding but his hooves are v deep.my mares hooves measure 6.5cms hairline to ground @ toe.she looks more like an 'epic' kind of girl.will the boas b ok or is there sum other way mabe using pads.also is it best 2 use pads with 'boas and or epics to maintain a good blood supply through frog and sole.
