The Screw Shoe: I haven’t tried them yet but it was a little slippery the last time I went running, and it’s going to get more so. I can run on ice like I was running on hard-packed dirt.   They work better than those slip-on spike things, but I can’t stop at the store if I’m wearing them. Now my only excuse for not running this winter is pure, honest laziness.

Those are 1/2″ sheet metal screws, by the way.
