Great neutral trainers


I'm a big fan of the new K-Swiss line, I bought the Blade race for triathlon, then purchased these to keep the mileage down on my racing shoes. Both feel light and bouncy which help on longer runs or after biking workouts when your legs are tired and your stride may not be perfect. Plenty of breathing room in the toe box, I've never had any blisters or discomfort. I wouldn't recommend these for any trail running however, they tend to roll laterally and don't offer the best traction in loose dirt, but then again that's not what they're intended for. They look slick but take work to keep white, defiantly worth it if you like to stand out of the crowd though.

conservative 4 star rating


I have high arches, run around 40 miles per week, and am a small framed runner. This shoe was great out of the box. As a triathlete, I run without socks, and this shoe was easy on the feet from the first run. The "blades" do grab a lot of pebbles, but not really a big deal. Not sure they are quite as good as my Newton Distances yet, but these are far more affordable. A lot of cushion for a shoe this light. Great for any distance, and worth at least 4 stars.




These shoes rock


I first fell for these shoes when I tried them on at the Twin Cities Marathon expo. But I had just broken in another pair of shoes. But those shoes quickly let me down so I purchased these shoes. I am very happy with the way they run. Well ventilated and very light. Both great features if I didn't live in MN. Need a sturdier shoe for the winter but come spring these will be back on my feet.

Minimalist shoe


I have been using these shoes for interval training on the road and the track. They are lightweight, comfortable and fast. I have put about 75 miles on them in 3 weeks and they still feel like I have nothing on my feet. I have been running a minimalist style without the benefit of the shoe for years, as the strike plate on my other shoes will testify. It is great to finally have a shoe for my style of running.

Fast, responsive, and sufficient cushion


Triathlete and runner. Typically train in asics kayano 16 and race in k Swiss k-kruze. Needed something a little more supportive than running flat for race day and decided to give the blades a try. Just right, with cushion and response. Feels comfortable for med long runs 10-13 miles on the road, but light enough for 5 and 10k's. Won my first race in these with a 6 m/m avg.

These shoes have such a smooth transition throughout the foot. The fit is very comfortable and I absolutely love how they run. The only downside is that these are a bit too stiff in the cushioning department for me. I still really love how they run but want a little more cushioning.

Awesome shoe!!


This shoe is awesome! It's very light and responsive. It cushions impact without a spongy feeling. Extremely flexible in the forefoot but the back half is a little more rigid. Buy it and you won't be sorry.

Awesome trainers!!Perfect for bootcamp


My trainer at bootcamp recommended these. What a difference over heavy running trainers. I use them 5 days a week in boot camp and have also raced in them (5K). They are terrific.

These fit the K-ona and are comfortable. They slide around a little when trail running, so i prefer the K-ona if i'm not on a paved road.

Best first run in a new shoe ever! I couldn't believe the comfort on the first run. I usually break shoes in with an easy 2 or 3 miles, with this shoe I just kept going for 6.5 miles. I run 4 times a week, avg. 6 miles a run and 2 weeks later I still love putting these shoes on and running. I am a Brooks convert to Kswiss!
