Being all into heavy metal, I have some leather armbands with small conical studs riveted into them, and I wrapped them around my hooves, strapped them down, and tied them with strong military boot laces! They actually work on grass/mud general offroad, but are useless on pavements and roads! I've made some interesting scratch marks on the local bandstand just before I fell on my face! I think studdies would be great for outdoors shows (see Merlyns nail studs), but only for proper off roading!
