Great protection from mud fever. Only issue is the sizing. I ended up having to get XL for my horses hind legs but he’s only a 14.2hh Connemara x TB so these will unlikely fit a larger horse with big bones. His front legs I got Medium extra wide which fit fine. Other than that these are great boots and easy to rinse off the mud.
These boots are a new design and have helped to keep my horse's legs clean of mud so he can get some turnout. They don't sit tight to the legs but allow the skin to breath & that is why I choose this design. So far they have done what I hoped.
