I am not a horse or mule person so forgive the ignorance. Why do you take the shoes off?
For me, I don't want to mess around with "borium shoes", often called ice shoes. Essentially a studded horseshoe. Flat shoes are sled runners on ice and snow. They have much better footing barefoot than plain shod.
When I build ice shoes, I prefer using Stoody tube borium (Like above) rather than that drill tek crap.
