The Synergy is a high performance climbing shoe featuring Boreal’s Zenith Ultra outsole that delivers exceptional grip whilst smearing on slabs. Designed to be used on both indoor and outdoor faces to help you push your limits.
Boreal Zenith Ultra rubber encompasses both the toe and heel box. The rubber compound is exceptionally sticky in order to provide sublime grip on marginal smears. Constructed from an asymmetric downturned last the Synergy’s shape improves the precise positioning of the foot.
As opposed to having a traditional midsole the Synergy uses Boreal’s Wrap Rand, where a rubber rand surrounds the arch of the foot providing support, positioning the toes in the optimum position for dexterity and precision. Removing of the midsole increases the sensitivity of the Synergy enabling nimble performance on volumes.
The upper is constructed from microfibre that safeguards against stretch over time. Boreal have included their own Friction Skin Rubber as part of the toe patch to provide additional grip for toe hook use.
For when you require seamless integration between your footwear and your body the Synergy is there to enable to perform without restriction.
