Hoof boot question

I'm thinking of buying a pair of Renegade hoof boots and I have a question about sizing. My horse measured 5"L and 4 1/2"W after a trim. Is this the size measurement I would use when ordering or should I allow for some growth?

Does anyone have experience with Renegade boots?

Thanks!

I'm not sure about your boots, but I let my horse grow till it was a middle between the trims (4 weeks after the trim, I do it every 8 weeks) and measured that time before buying. I use bares though.

I work at a tack shop that deals with horse boots. In my opinion, your best bet would be to take a tracing of your horse's hoof and take it in to a tack shop to get expert advice there.
Generally, however, the manufacturers of the boot give measurements for people to go by, and correct for any errors within THEIR mesurements - so I would get the closest size to your horse's actual hoof size as it is now, otherwise it may be too big.
