Boreal Synergy is designed for optimum feel. A highly aggressive last shape is carefully blended with superb sensitivity and supremely sticky BOREAL Zenith Ultra ™ rubber to enhance the natural qualities of the foot; a true synergy of design, materials and craftsmanship, enabling you to push your limits on any bloc, both indoor or on rock.
Synergy features a highly asymmetric and downturned last to optimally position the foot on steep rock. The lined, synthetic upper with strap closure comfortably holds the foot , and ensures minimal stretch over time.
The rand and toe patch are constructed from a single piece, and combined with an area of our Friction Skin rubber coating, provides outstanding friction and sensitivity for toe hooks. Eliminating the midsole results in a highly sensitive and soft feel, ideal for marginal smears and standing on volumes. Our soft and sticky Zenith Ultra ™ rubber compound is optimized for performance on marginal smears.
Synergy is ideal for competition climbers and boulderers looking for maximum sensitivity and feel.
