Goat Heads, which I've been wearing since the early winter, are, thus far, holding up better than any other spikes I've worn. These little suckers have 28 biting edges per spike, and the screw length is a touch longer than that of similar studs. They're made of cold-forged, heat-treated, corrosion-resistant steel, and deep serration on the underside of the head stops them from backing out. I haven't lost one yet, nor are the spikes mashed, deformed, or any less shiny than the day I put them on. And they really stick, having passed my stand-on-a-flat-rock-and-pirouette test many times. A pack of 30 Goat Heads will cost you $25, which includes a tool for putting them in. That's a pretty cheap investment for fewer bruises and soggy undergarments.
