A pard tried the microspikes on a goat hunt last year. Epic fail. Same slipping issue and overall lack of traction. One of them broke on the second day. They seem best suited to the elderly shuffling across an icy driveway to retrieve a newspaper. Short of full on, heavy, mountaineering crampons, the best I've used so far are the old CMI in-steps. They can still be found on ebay.
