BEST FOR: Racing, midfoot runners, narrow feet.
THE TEST: The Roclite 243 is like a barefoot slipper with fangs. There is very little shoe underfoot (just six millimeters up front and a nine-millimeter heel), and what’s there is a Gumby-like invertebrate—you can bend any part of the sole in any direction. That flexibility, combined with an extremely secure midfoot and reasonably secure heel (there’s no external heel counter), made it the most agile and efficient shoe here. It’s an ideal racer on flowy trails, though most testers needed to ease off the gas when the turf got more technical.
THE VERDICT: On rolling trails, they flat-out scream. But they probably don’t have enough guts to be your everyday driver on loose, rocky trails. High-volume feet, steer clear. 8 oz; 3 mm drop
