Mad Rock's iconic Flash has finally gotten a total redesign. The Flash's blend of comfort, durability, and performance has lead to multitudes of climbers embracing it. Over the years, the Flash has been the subject of rave reviews and has won many accolades. So what could be done to make it even better? Well, 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 also remains one of the only climbing shoes on the market to incorporate Shock Gel, to reduce the impact force on the heel. An everlasting poly-carbonate midsole gives the Flash 2.0 a consistent and predictable flex through out the life of the shoe. And now it comes in Yellow!
