Yes, these are crampons. Well, sort of. Pedestrian crampons. But with 10 spikes, each one 3/8-inch long, and made of stainless steel, the Kahtoola MICROSpikes could do real work paired with hiking boots or running shoes to provide traction on snow and ice. A “shoe harness” made of a stretchy rubber flexes as you step in, then cinches tight. And they’re so packable and light that people (me, for example) will be tempted to try and employ them for easy mountaineering. My pair arrived in the mail yesterday, and I can say I am intrigued. . .
