BOA Fit System: An easy fit ready for the technical trails

Not many trail shoes use the BOA tech as their lockdown system for the reason that a lot of athletes still prefer traditional lacing systems. However, with Cyklon, you might just change your mind. 

The BOA Fit System in Cyklon gives both customized and convenient lockdown. Runners also find it very effective in steep downhills. And for those who run during winters, it's especially helpful because, in just a few turns of the dial, you can readjust your fit, preventing spending too much time in the cold.
