K-Swiss isn’t particularly known in the Philippines as a company that makes running shoes so I was quite surprised when I saw several models in the local market. One particular shoe that caught my eye was the K-Ona.
K-Ona is definitely a looker with its design. It looks very breathable but what surprised me was when I lifted it—at mere 9 ounces it was one of the lightest shoes I’ve ever handled!
Judging by looks of the K-Ona one may think that this is just your regular cushioning shoes for those leisure runners but the K-Ona is anything but that—it was the pair that Terenzo Bozzone wore at the recent Ironman 70.3 CamSur (Philippines). Not only was the K-Ona Ironman 70.3-certified (half-Ironman), it is also Kona-certified (full Ironman). A very impressive ultra-lightweight shoe!

Of course shoes are not meant only to be looked at, but to be worn. It was love at first step as I tried the K-Ona for the first time and run with it on a treadmill. The first thing I noticed was how comfortable it was, not to mention that you hardly feel that you’re wearing a shoe because of its light weight. Of course you know you’re wearing one because you land softly on the surface.
The Test: Standard Chartered Singapore Marathon
Four days before SCSM I decided to have a piece of Kona myself, K-Ona I mean. I’ve never had this much fascination with a shoe before and that same night I had it for a 6.75K test run. It was one of those rare shoes that you need not break-in—it was excellent out of the box! With just a single test run this shoe earned my trust that I decided outright that this would be my SCSM pair. They said never to try anything new during race day but hey, if it’s good enough for Ironman, it’s good enough for me!
Unlike other shoes that force you to conform to, the K-Ona is perfect for forefoot and heel strikers alike because of its excellent cushioning in these areas. The rubber outsole is also very durable as it hardly exhibit any wear and tear even after a full marathon. And unlike other shoes that feels hard after a long run, the Superfoam remains soft and comfortable even after the end of the 42K spree. I’ve never had a shoe that was this comfortable that I actually never worried about my feet all throughout the run. The flow cool system was also better than other cooling system used by other brands as you get unobstructed air flow from virtually all directions, which proved to be very useful for those humid runs like SCSM. All these without sacrificing weight!
Among other noticeable features of this shoe are the excellent grip (despite the holes on the soles), excellent fit, seamless construction, no “hard” zones, and interesting shoe laces.
The only drawback of this shoe was that it is definitely not for those who need stability or motion control as the midfoot shank provides only a moderate amount of control. You may also want to think twice before running into that puddle of water or mud as it may enter through the holes under the soles, although it may dry faster than other shoes would.
