Update: we are officially in size 2s up front! The flatter foot took some finagling to get on (and a bit of cleaning up the edges of his toes) but with some old nylon socks underneath we got to go on a 20 minute walk with our new boots! No room for pads or pastern wraps so we aren’t turning out in them quite yet.
Anyways, I’m probably projecting some hope on him but I really think he was striding out more in the boots. He always tracks up a good bit behind but has been… short striding? Pony striding? Tiptoeing? In front. I really felt like I could see more reach with his shoulders just in the 20 minutes or so of handwalking in the boots. He was 100% happier to go on the gravel and hard patches, for sure!
Next project is to get boots for the hinds - preferably to fit 2 or 3 degree wedge pads. He’s got flat or negative angles back there, but not much toe to take off. Maybe a month or two in some wedges will relieve his back a bit. I’ll be talking to my farrier first of course!
