we use Cavellos on both of our horses and one of them, like your Fell, has no foot left to nail to and extremely tender feet but also with dropped soles.
They are brilliant, really easy to put on and they seem to stay put for most general riding things. I use the pastern wraps with my Hanovarian as he sems to get alot down the front of the boots, but the Haflinger has just the boots on and she seems fine.
If fact, i worked out, that they are cheaper for me than the shoes because they were losing so many shoes just after they were put on that it was costing me a small fortune to keep having to get the farrier in to replace them.
Hope this helps
