The Overview:
Running is currently deep in the throes of a minimalist movement; less materials and less heel seem to be it’s biggest focus when it comes to running shoes. As discussed in our Newton Trail Running Review the reason behind this mini revolution is to return current human running movements to it’s natural state, ie pushing off the ball/front of foot and a quicker cadence. La Sportiva is renowned as a mover and shaker in this coup d’etat and the Vertical K is no different. La Sportiva Vertical K, in fact, brings minimalism to trail running, which in the past has relied on burlier, see heavier, running sneakers, or even lightweight hiking shoes. Traction was the main focus back in those days. Vertical K’s combine minimalistic design with sticky traction, and still manage to keep the weight of the shoes at a whopping 6.9 oz.
The Test
After lacing these up, and walking around, my first impression was that they didn’t feel like much, supportive, yes, but not much cushion. But I guess that’s the idea: minimal. I was a little wary at first since that I have bad knees, and could just imagine the pounding they were about to take.
I took these on an uphill trail run up my favorite access road in Aspen, sunny Smuggler Mountain and then to the adjoining trails at the top of the mountain. The trails range from loose and dry to tacky with lots of roots. Throughout my run I noticed that these shoes were incredibly stable, the cloth wrap seemed to prevent any lace-slip and also provided a secure fit and enhanced support. Other features I noted were traction and weight. I had no trouble running over loose, sandy rocks or quickly changing my direction to avoid an oncoming hiker or dog. The lightness added to my level of endurance; I’d imagine it also helped keep knee pain at bay.
Note: When running with the Vertical K’s and all minimalist shoes, it’s important to focus on running on the front part of your foot, rather than heel first. Your muscles need to be trained how to properly run. This is one slight disadvantage, because there is no zoning out while running. But your body will thank you.
Cons
The material on the ankle area came up a little too high and did chafe me a bit. I believe this could be easily remedied with orthotics or insteps. Plus, the actual style of the shoe isn’t incredibly eye appealing.
The Rating
4.5 (out of 5)
Design: The science behind these shoes are incredible; their both lightweight, minimal and provide great traction. +1
Style: They are a little reminiscent of water shoes, which isn’t exactly a good look. -.35
Durability: The traction on the soles and toe protectors combined with the actual construction will ensure these shoes last a while. +1
Performance: You have your cake and eat it too: weight to traction ratio, plus support make these a game changer. +1
Comfort: Ankle area is a little too high, but that will be subjective from one foot to the next. -.15
