EXCELLENTAbout This Shoe
The Boreal Synergy climbing shoe embodies the perfect fusion of aggressive performance and sensitivity, designed for climbers who demand precision and confidence in their footwear. With a high asymmetrical design that conforms closely to the foot, the Synergy maximizes power transfer to the toe box, allowing for explosive movements on overhangs and technical routes. The shoe's soft stiffness rating enhances sensitivity, providing climbers with an intimate connection to the rock, enabling them to feel and manipulate footholds with unparalleled accuracy. Whether tackling a steep sport route or a challenging bouldering problem, the Synergy is engineered to enhance every aspect of footwork. Constructed with Boreal's proprietary Zenith Pro rubber, the Synergy offers exceptional grip and durability, making it an ideal companion for both indoor and outdoor climbs. The shoe features a velcro closure system that allows for quick adjustments, ensuring a secure fit that can be fine-tuned for varying foot shapes and climbing styles. The synthetic upper material not only reduces stretch over time but also provides breathability and comfort, ensuring that climbers can focus on their performance without distraction. This thoughtful design extends to the shoe's sensitivity level, rated at an impressive 9 out of 10, allowing climbers to feel every nuance of the rock surface beneath their feet. In terms of performance characteristics, the Synergy excels particularly in overhung terrains, where its aggressive profile and robust rubber provide the necessary grip and support for dynamic movements. While its performance on slabs is rated as moderate, it shines in smearing and toe hooking, making it versatile for varied climbing styles. Good edging performance allows climbers to tackle vertical routes with confidence, while its ability to handle heel and toe hooks ensures that climbers can execute technical maneuvers with precision. The shoe’s performance in cracks is satisfactory, making it a solid choice for multi-discipline adventures. Comfort is paramount in the Boreal Synergy, with a comfort level of 7 out of 10 striking a balance between performance and wearability. Sizing considerations are essential, as the shoe is designed to fit snugly; climbers are encouraged to try on a pair to find their perfect fit, considering the shoe's aggressive nature. What sets the Boreal Synergy apart is its ability to combine aggressive performance with comfort, making it a standout choice for both competitive climbers and enthusiastic weekend warriors. The Synergy empowers climbers to unleash their potential, helping them conquer challenges and push their limits, regardless of the climbing discipline they choose to pursue.
