Yes, good. I saw a pair on too cute the other day that were bedazzled to hell and back and it was the best day of my life
iirc they have the dual purpose of stopping the horse from drawing blood if they accidentally kick their leg while running, and also minimizing noise on hard surfaces
(normal) hoof boots are also good for if they have an injury and need extra protection or as an emergency replacement for if they lose a metal shoe while out riding Mini horses who are therapy or service animals also wear them for traction on smooth floors (most hoof boots are nowhere near as fashionable as these ones, of course)
oh yeah increased traction-you'd think a DoWaS reader would remember that but nope the extra protection for an injury thing is very obvious in hindsight thanks!
