The Atomic Redster C9 is a lightweight, stable boot that’s packed with power – helping you turn every kick into rapid acceleration on track. Its light and thin low-cut inner boot gives you the freedom of a running shoe, while the pre-shaped heel pocket ensures an excellent heel hold. Our new carbon-loaded heel counter increases stiffness without adding weight for exceptional stability, control and performance. And fit-wise, the boot’s 3D Race Lacing System wraps your foot perfectly, while our Atomic Race Fit anatomically matches the natural curves of your foot – to keep you precise, pressure-free and race-ready, all day long.
