When you line up at the start of an epic 100-mile footrace, what shoes do you choose? We asked top ultra runners.

This weekend is the 2015 running of the Western States 100-Mile Endurance Run (WSER), a historic trail ultra that sends its 300-plus competitors from Squaw Valley ski area to the Auburn High School track in northern California. Runners traverse high alpine terrain, descend into scorching canyons, and cross through running water along the way.
We wondered what shoes runners were going to wear for this task. Here are what a few top athletes, many of whom are expected to contend for the win or a top-ten spot this Saturday, noted as their ultra footwear of choice.
