I have dealt with club feet a couple times, and I would definitely pass on him, no matter how cute. That is a problem that is not always curable, unless it is slight (which his isn't) and you have to stay on top of it all the time. There are so many horses without issues, just hang tight, you'll find the right one.
SUJ, I'm all for adopting from rescues, but so many of them make you jump through such ridiculous hoops to adopt, that often times, for most people, it isn't worth it, especially when they can go BUY a horse without strings for the same as an adoption fee from a rescue. It really is a shame, as there are many good horses sitting in rescues that will never be adopted for this very reason.
