Lightweight and incredibly fast, the Mizuno Rebellion Flash 2 in Neo Mint/Vintage Indigo/Hint Of Mint introduces the Smooth Speed Assist (SSA) and upgrades to Mizuno Enerzy Lite+ for an even softer underfoot feel and faster transition. By combining a full-length plate with Mizuno Enerzy Lite+, you would think Mizuno had given the Wave Rebellion Flash 2 enough forward momentum. But by creating large cut-outs beneath the plate that allow it to move more freely, giving a more explosive pop of power, and creating a shaped geometry to the shoe that provides both stability and an always-forward sensation, they have created extra speed for serious PB assistance. A full rubber outsole gives traction and soft landings, while the breathable mesh upper uses a lightweight heel counter and internal support straps to give you locked-in comfort. Features include: Breathable mesh upper, Lightweight heel counter, Triple shoelace loop, Internal support straps, Smooth Speed Assist (SSA), Mizuno Enerzy Lite+, Stack height 35mm / 34.5mm, Full length, glassfibre reinforced wave plate, Full rubber outsole. Made for those days when you want to push the pace. The Mizuno Wave Rebellion Flash 2 now includes SMOOTH SPEED ASSIST to help you achieve your ideal gait and a glass fiber-reinforced wave plate.
