Trail and mountain running definitely requires you to have specific footwear equipment. This is where La Sportiva comes in and introduces the Vertical K Trail Running Shoe ($115). This ultralight marvel (7 ounces only) stands on a two-inches thick EVA foam mid-sole at the heel called MorphoDynamic that absorb everything mountains have to offer while providing traction. The shoe is fully wrapped with Lycra, which eliminates the need for a tongue and provides breathability. La Sportiva Vertical K Trail Running Shoe will be available to all in the spring of 2012.
