Screw Shoes

Just finished a 1.5 mile test run in these in the worst conditions imaginable: partial snow, partial ice, invisible black ice, and exposed dry pavement. Solid snow would be better. These things are great. They are "crunchy" and I think I'll prefer them in hard-packed snow. But there was zero slippage on black ice, ice, snow, and pavement. Very cool.

I might get shorter screws--even though I shortened some of them, it's a little prickly. I'd rather replace screws on a regular basis than feel them poking at me.

Here's the shortest and coolest link on screw shoes.
