The Salomon Synapse was one of our top sellers last year, and is a responsive boot with excellent comfort levels and durability. Starting internally, the Synapse features Salomon's Balance 3 Liner that uses a multi density foam throughout for a customised glove like fit and secure heel hold. Externally the Synapse is founded on Salomon's Spring outsole, which incorporates Dual Density EVA for cushioning and response, and injection moulded arch supports for foot stability and optimal power transmission to the board. To finish things off, Salomon's Powerlace Pro locks you in quickly and easily and won't loosen off.FEATURES:Flex Rating - 8 (1=most flex/10=least)Spring OutsoleMystic 3 FootbedPowerlace ProBalance Level 3 liner w/Full Custom Fit foamGLOSSARY:Spring outsole:Uses dual density EVA and a thin rubber outsole to create a plush, yet responsive platform.
