Wired's nice examination from July of the arguments for jettisoning your cushiony running shoes and getting some foot gloves. I have to say, I've been adjusting my stride lately to a shorter, choppier gait and and I think these guys may be right. I'm going faster. I'm also using old running shoes alot. I've got six pairs dating back four years that I rotate around. I'll forgo the foot gloves. Though a guy on our college team, Walt, trained and competed barefoot. We're talking late 70s, folks.
