The Boundary 107 Pro’s middle-of-the-road radius (20 meters) enables turns of any shape. From hop turns in icy chutes to lower mountain bobsled runs, the Boundary Pro 107 was never a chore and reflects a significant power boost for Black Diamond in the all-mountain category. A lively early rise tip transitions into a rigid, traditionally cambered platform underfoot that gives way to a slightly rockered, fairly stiff tail. Smear it in times of glory or stand on it in moments of doubt.
The mounting point is right where I like to stand on a ski—a little bit forward. To me, less tip length translates to easier, faster turns. My stance is on the upright side, so I don’t need a whole lot of tip in front of me to make me feel stable at speed. While the 184 turned like a 176, it had the stability you’d expect from its true length. Its slightly tapered tips and tails address any sort of hooking that you might expect out of a ski this curvy.
However, folks who ski traditionally (driving the tip to initiate every type of turn) might find themselves overturning on these. If I’m going to drag my skis up hill, they better be sort-of light, and they better be fun to ski when it’s time to go down. In the case of the Boundary Pro 107, Black Diamond balanced uphill weight with downhill shredability well. It’s the first touring ski that I really wouldn’t mind skiing any day of the year, in any condition. —Alex Buecking
