I would spend the money on a decent supplement or forage analysis instead, to produce good quality hoof from the inside out . Healthy hooves are best off with nothing but water on them imho.
I don't necessarily agree that the hooves, sole and frog dont benefit from the application of something in this wet weather. Same in dry weather, when applied to wettened feet. It's personal preference, and I prefer to. It's nothing to do with poor quality feet and/or nutrition. Neither apply in my case but I still find certain hoof products beneficial
