If any of you have done hours of surfing as I did about the various hoof boot options out there, you already know that all the boot manufacturers recommend that the sizing be done very carefully and that the boot fits well from day 1.
We all also know that the newly transitioned to unshod hoof will change shape over time. Some say the heel bulbs will spread out, the entire hoof capsule may widen, flares will grow out, toes will be shortened over time and heels will end up lower. All this points to the boots we picked on day 1 becoming more snug, right?
My horse decided to go the other way with this. When we first pulled his shoes, there was stretched white line everywhere, flares galore. Now that his new hoof capsule is growing in tighter, his boots are now too big!! ARRRGGGHHH!!! Who would expect that??? Headdesk!!! Luckily there is a market for used boots, so I am in the process of trading down, but just wanted to make others aware of the potential problem. I don't expect to still be playing this silly hoof boot game in a year or so, but for now he needs them for trails and I have to do a do-over in terms of boots.
If this info saves anyone else a few $$, that's good enough for me.
