I think I mentioned it in a previous post, but we are seeing what happens when Gus puts on the Denoix Suspensory Support Shoe from grand circuit. It's not that expensive ($20), so I think it's worth a go. In theory the shoe is designed to help float the toe a bit and reduce a "stabby" motion on a leg that has reduced range of motion in the lower limb.
I'm not sure it's going to be like Cinderella's slipper and cause princes and birds and fair godmothers to show up, but if it helps him move more comfortably, well then, why the hell not.
Honestly, as much as I've tried to educate myself on hoof care and hoof shape and trimming, I know literally nothing about specialty shoes or how they do what they claim to do. I'll make it a point to ask my farrier some questions as he's attaching it to Gus' toostie and report back.
