I put up a post last year about him which had exactly this effect and led to lots of people advising me to trim him - even though they had never watched him move or managed to identify why he had the deviation he does. The full post is here http://rockleyfarm.blogspot.co.uk/2013/12/my-take-on-this-less-than-perfect-hoof.html .
I can appreciate that it can be difficult for those who haven't met him to realise that this horse really is much happier with his odd feet than he would be with feet which were trimmed to make them look more conventional.
So now that Freya is here hunting him I decided that it would be a good idea to take my head cam and get some footage of them out and about. Its not easy to make out in this clip because of the speed but there is some quite nasty terrain and this is his 4th days' hunting over a 2 week period.Aldermans Barrow from Nic Barker on Vimeo.
The proof of the pudding...
