Merrell Sonic Glove Trail Running Shoe - Men's - $93.71

If the Merrell Sonic Glove Men's Trail Running Shoes were any thinner, they'd be invisible. But as they are, they provide just enough protection to get you down the trail without poking a hole in your foot. Lightweight mesh uppers ensure total breathability, so your feet don't become globing masses of sweat while you run. A little lower down, Merrell put on Vibram Trail Glove soles for excellent traction with the minimal possible thickness. - $93.71
