Anyone else on here have a horse with around 10" of bone who could recommend some knee boots. I bought the large Westrupp Shires ones the other day and the velcro does not reach!
Leather ones have hugely long straps - I had to use cob size ones on a 17.3 warmblood and they were on the second to tightest hole. I think Jefferies do them and I know Calcutts do.
I have the Jumpers Horse Line leather ones with felt backing on my cob mare. She's got about 8 inches or bone or so and is on the smallest hole with loads (and loads) of space, probably another 10 holes or something so would fit almost any horse
