I learned today that how a hot shoe is quenched makes a difference to the grip it gives - I never knew that! Last time Luka was shod a different farrier did him and while he had, under slight protest, fitted road nails we were still slipping on the roads. I got my normal farrier back to have a look since I couldn't see any reason for it, though after some reasonable trots they were either improving slightly or Luka was getting more careful. It turns out that if you quench a hot shoe in one go it hardens the steel off more than if you do several short dips with a small rest inbetween, and the harder steel gives less grip on the road. Did anyone know this? In over 40 years I hadn't heard of it, but it's certainly made a difference to us.
