I finally had a chance to try these tires out yesterday. I rode about 24 miles on city streets and bike paths and I'm happy with these Innova tires. They did really well on packed snow, slush, icy patches and pavement. The only time I had a little trouble was when I tried to ride through several inches of heavy slush (with an uneven dirt surface below) on the side of a busy road. Also, riding through 4-5 inches of untracked powder was a tiny bit slippery.
The few times the front tire would start to slide out, the traction was predictable enough I could maintain control. I didn't come across any long stretches of solid ice, but I'm eager to see how they do on that. All in all, they seemed well worth the money. Time will tell how the studs hold up to riding on a lot of pavement.
