IME, gloves aren’t meant for wider than long hooves, at all. Especially spade shaped hinds. The fit was horrendous.
Do you have a good farrier? Try the poly steels up front and a flat steel shoe behind. The benefit of plastic is that the shoe can be cut after application to get a perfect tight fit. I also think the extra height in front, both from the thickness of the shoe and the fact that plastic shoes will “float” more on soft ground vs. steel which “sinks” due to less surface area, gives a bit more freedom in the front end. I’ve literally rested them for 2 years before when riding on dirt/sand/grass primarily.
