Bovine "shoes"

[UrsulaMejor]

So Why Don’t Cows Need Shoes, Too?

Basically, cows just aren’t expected to do as much stuff as horses are (and across such a wide variety of terrain). We don’t race them; we don’t use them for ranch work à la Yellowstone; we don’t make them carry tourists around Central Park in carriages; and so on. Back when oxen were a common draft animal for farm work, even into the 20th century, they were often shod [PDF]. Since oxen, like cows, have cloven hooves—split into two—they actually wore two separate “shoes” on each foot.

Neat.

I think it'd be neat to have to nail in "cowshoes" with different properties; unable to take them off and on again at will but easily done at your local medbay with the right materials from mining.
