Most people might consider waking up at 5 a. m. to run to the top of a mountain a form of cruel and unusual punishment, but its what you live for. Luckily, the Montrail Women's Mountain Masochist III Trail Running Shoes share your penchant for pain, so you won't hear them whining about steep climbs, loose dirt, and boulder strewn ascents.Their synthetic mesh upper puts a premium on breathability, making them a great choice when you don't anticipate a whole lot of mud or rain. Their Fluidfoam midsole cushions your feet when the trail turns from fast, rolling singletrack to an all out suffer fest up steep and rocky ridges. For added support, the midsole of each shoe is supported by a Montrail's Fluidframe technology and below that is the trail shield, which runs the full length of the shoe for added protection from trail debris. The Gryptonite rubber sole lives up to its name with an ability to bite in the most challenging and technical terrain.
