Forces only exist as a result of an interaction. Whenever there’s an interaction between two objects—a climber and a sheer rock face, for instance—there’s a force upon each of the objects. Contact forces are the types of forces that result when the two interacting objects are perceived to be physically contacting each other. So, it’s simple science that we’d make a versatile, can-do shoe that fully embraces the laws of physics; thus, the Force X.
SCARPA’s Force X is happy at any crag, gym, or boulder park, but it really shines on long trad routes. Constructed with suede leather that molds to the foot, it features a liner in the back half of the heel pocket, along with a padded mesh tongue for comfort. It’ll perform on edges, and remain sensitive on slabs. There’s a reason for that. And the reason is called Vibram® XS Edge rubber. Developed to deliver maximum grip, XS edge doesn’t stretch in hot temps and maintains its resistance to plastic distortion, holding a consistent edge in hot and cold environments.
Active Randing has been around for a while. It strives to get maximum sensitivity for your feet while still being able to hold an edge, and that “activity” comes from tension. The Force X uses SCARPA’s V-tension randing, a process that employs the Active Randing™ principles of high-end power transfer, but uses more forgiving tension. When you’re at the wall, think maximum performance with less pressure and compression in the toe area. Translation: long, comfortable days in the hills. Coming in men’s and women’s anatomical lasts, the Force X uses two power strap closures and a flat last for all day comfort at the gym, crag, or long trad route.
SCARPA athlete and author Majka Burhardt touts the versatile value in the Force X as a versatile performer. “I have two pairs in different sizes,” she says. “One of them I size small for more technical cragging, and the larger pair I use on longer days in the mountains when comfort is top priority.”
When the interaction of the climber and the wall ceases, the two objects no longer experience the Force X. Forces can only exist as a result of an interaction—the result of an experience. It’s the beauty of science and love. And, after all, what’s a love affair with climbing without physics?
