Mad Rock's iconic Flash has finally gotten a total redesign. The Flash's blend of comfort, durability, and performance has lead to its embrace by multitude of climbers. Over the years, the flash has been the subject of raving reviews and has won many accolades. So what could be done to make it even better By mixing this time tested classic with their science proven innovations. The traditional leather upper has been completely replaced with 100% Synflex, a synthetic stretch material, to offer performance while maintaining a consistent plush fit. The Flash 2.0 is also still one the only climbing shoe on the market to incorporate Shock Gel, to reduce the impact force on the heel. An everlasting poly carbonate midsole give the Flash 2.0 a consistent and predictable flex through out the life of the shoe.
