After much internal debate as to the need for another item to add to my gear collection, I finally purchased a pair of Kahtoola Microspikes. Yes, I know the trails are nearly snow free and spring is around the corner but I got a great price and free shipping so I couldn't pass on this deal.
Another thing that prompted me to make this purchase was the fall, and subsequent ankle break, of a friend during a training run on ice. My screw shoes have served me well on many runs this winter but the Kahtoolas offer a more aggressive grip that gives an added measure of safety when descending steep, ice-covered trails. I hope I don’t need these until next winter but it’s nice to know I’m good to go if Old Man Winter decides to hang around a little longer.
I can't make a first-hand recommendation but I've gotten several good reports from trail-runner friends that used the microspikes this winter. I'll do a complete product review after I actually get to run in them. Hopefully, not for a long while!
