Vibram KMD Sport LS Review for Forefoot Running

I have been running solidly in what I consider, a better, more protective and comfortable version of the Vibram KSO, and that is the Vibram KMD Sport LS. You’ll love these shoes, especially if you do triathalons.

The Vibram KDM Sport LS, also known as the KomodoSport LS, is an excellent road running shoe (5 km- 10 km races) and is my preferred Vibram shoe. I loved the KSO, but I prefer the KMD Sport LS because, although it may not be as thin in the outsole as the KSO, the KMD Sport LS is more flexible in the forefoot and the upper is made of softer materials, making the shoe more comfortable to be worn without socks. Also, the KMD Sport LS handles the rain better than the KSO, and it think it’s because the bundgy-cord closure allows for a more secure and tighter fit. Overall, The KMD Sport LS is more comfortable than the KSOs.

The KMD Sport LS is great for running, cross-training, walking, hiking, the gym, running on the beach, running in creeks and water sports. Basically, you can wear them for everything!

The outsole of the KMD Sport LS is thicker than the Sockwa X8, Vibram KSO and the Bikila LS, so you don’t feel small pebbles and twigs, but it still gives you enough sensory input at the foot to help you avoid heel strike when running.

The upper is abrasion-resistant and is durable and hard to rip. The upper is also a bit thicker and stretchier than the KSOs, so the KMD Sport LS is a better alternative to running in cooler weather and allowing for a better fit. The toe sockets stretch nicely too, so they fit properly if you have long toes. Another thing I like about the upper is that if it gets muddy, it does not stain, the mud wipes right off. That’s why these shoes always look new, no matter how much you run in them.

I also appreciate that KMD Sport LS outsole is similar to the human bare foot in that it’s smooth. Remember, you don’t want a running shoe that has thick, protruding tread because it is bad for the knees. Even though the outsole is smooth, the rubber still provides excellent traction on slippery surfaces. In my experience, this shoe grips very well for all terrains.

Vibram KMD Sport LS Review for Forefoot Running

We know that barefoot running shoes are a proven strategy to build stronger feet and improve running form. This is why the KMD Sport LS is so amazing, because they mimic true barefoot conditions, which will help simulate your foot’s muscles, which in turn triggers a release of a cascade of stimulation that strengthens the ankle, calves, knees, hamstrings and core. You will become nothing but stronger in these shoes.

I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
