This updated model features a new more precise fit, a unique curved midsole for maximum support, and a PAF heel system provides comfort on long technical routes. The Boostic is the most supportive shoe in our Specialized Performance category.
The Differentiated Tension System, made possible by the PAF heel, allows us to tension the inside and the outside of the shoe differently enabling us to truly dial in the intended characteristics of a specific model. This unique technology not only transfers power directly to the big toe, it also helps keep the foot in an optimal position for power transfer and laser precision. DTS also ensures that the shoe keeps its shape and intended climbing characteristics throughout its entire lifespan.
PAF (Pressure Absorbing Fit) is an innovative heel system that helps both spread the force of the heel tension and increase the fit of the heel. The Active Rand rubber is interrupted behind the heel to reduce pressure on the achilles tendon and connected with 2mm XS GRIP2 rubber, that works like a bridge and allows full adaption to the shape of the heel while still providing dynamic forward pressure to focus power over the big toe. The holes on the side of the heel indicate the tension applied, which varies between 1 hole for light tension, 2 holes for mid tension and 3 holes for strong tension.
