Bottom line

The K-Swiss Kwicky Blade-Light is a favorite with triathletes, marathoners and anyone who enjoys a soft shoe with a sock-like fit; those who don't like the softness may find the sole a little too flexible. Reviewers say the Kwicky Blade-Light offers good stability for overpronators, especially considering its light weight.

Fit and flexibility

A smash fit. The K-Swiss Kwicky Blade-Light's fit is a hit with triathletes and marathoners alike, who say its seam-free upper is so comfortable they can wear this shoe without socks. Testers for the Runner's World Summer 2011 shoe guide also rave about the Kwicky Blade-Light, particularly the "excellent arch wrap," and praise how well this shoe moves with your foot.

Reviewers say the Kwicky Blade-Light fits true to size, and that the sausage-link laces -- which do somewhat resemble a chain of connected sausages -- actually stay put where you tie them. "The toe box fit perfectly: not too tight nor too lose," writes a marathoner who blogs at TheBullRunner.com.

Comfort and cushioning

Shy around water. Although a shoe this light -- approximately 9 ounces -- must sacrifice much cushioning, the Kwicky Blade-Light receives universal praise for having better cushioning than most other shoes of similar weight. "It allowed me to feel the road but was cushioned enough to make it feel good," says one tester for a 2011 Runner's World review of the Kwicky Blade-Light.

Another owner sums up the general user consensus, explaining the shoe provides a "responsive, cushy ride, which feels fast anf light." A few users do call the pliability excessive, but they're also very clear that it's simply a matter of opinion. Those who enjoy a soft, light and flexible shoe almost universally love the Kwicky Blade-Light.

The K-Swiss Kwicky Blade-Light's open-mesh upper allows some breathability, and is coated with a hydrophobic finish to repel water. The shoes are not completely waterproof and will still get wet if you run through puddles. A double-edged sword: The vents along the sides and bottom of the sole pump out any water that does get into the shoe, but also provide a way for it to enter.


Better than expected. The Kwicky Blade-Light is awarded Best Debut in the Summer 2011 issue of Runner's World's iconic shoe guide; the editors recommend it as a versatile distance shoe for efficient runners or a supportive racer for those who need some corrective support. A firm medial post, broad base and plastic shank help stabilize your foot, although severe overpronators may prefer a motion-control shoe like the Brooks Beast '12 or Ariel '12 (*Est. $130) .

Most stability shoes tend to be a little klunky, and marathoners flock to the Kwicky Blade-Light for its ability to support without weighing you down. One long-distance runner posting to RoadRunnerSports.com says the shoes still allow free foot movement, even with their light pronation control. "They make you feel like you are flying since they are so light," writes another reviewer posting to Amazon.com, who's happy that these shoes allow a comfortable midfoot strike. (The Kwicky Blade-Light has a 10 mm drop from heel to toe.)

"The shoe provides super stability and ample cushioning," writes a marathoner and blogger known as "Jaymie" at TheBullRunner.com. She explains she is a flat-footed overpronator and that her feet are "very choosy with shoes."

The Kwicky Blade-Light is also available in a Neutral version (Est. $135) , which draws high praise from editors in the Winter 2012 Runner's World shoe guide. They say that the independent crash pad, beveled heel and plastic shank on the Kwicky Blade-Light Neutral still provide some mild stability if you need it on longer runs.


Depends on your mileage. Scanty user feedback is most telling when we try to evaluate the Kwicky Blade-Light's durability. It's particularly popular with marathoners, who say they usually buy a new pair every three months when actively training -- approximately 300 miles or 500 kilometers. However, one commenter at TriBomb.com who weighs more than 170 pounds has gotten more than a year of use from the Kwicky Blade-Light, which gives us hope they'll hold up well to frequent abuse.
