2013 Triathlete Buyer’s Guide: Running Shoes

K-Swiss Blade Light Run 2.0

$95, Kswiss.com
The draw: Freedom of movement and ample cushioning

This neutral, 9.7-ounce update to one of the brand’s most popular models begs for speed and would work well as a performance trainer or a marathon race shoe. The blades on the outsole have been repositioned on the 2.0 to cater to a mid-foot or forefoot strike. The heel-to-toe drop is now 8mm, versus 12mm on the original. The arch structure is low and there is virtually no support, so only the most efficient runners will enjoy the blade Light run 2.0. The seamless upper offers a slipper-like feel to decrease the possibility of hot spots.
