Redefining Peak Performance.

We're a group of Pioneers whose goal is to constantly push boundaries and ensure athletes perform at their peak. Our roots are on the mountain, and launching the BOA Fit System in alpine skiing was a natural step for us. We worked with the world’s top ski boot brands to build the best-performing boots on the mountain, delivering micro-adjustable, precision fit for superior heel hold and edge-to-edge control, engineering them to perform in the toughest conditions.

H+i1 is the fit solution for Alpine Ski applications. With 35,000 hours of development and 5,500 hours of field testing, H+i1 helps provide a micro-adjustable, precision fit that uniformly wraps over the midfoot, delivering superior heel hold and edge-to-edge control in the toughest conditions.


Created specifically for Alpine Ski applications, SS3 is a steel lace that works in the toughest conditions and enables the H+i1 dial to wrap over the midfoot,  locking the heel firmly into the heel pocket for a more connected fit.
