Atomic Pro C3 is built with a low-cut like a running shoe, which delivers epic natural movement and makes each stride feel freer. A 3D Lacing System wraps the foot perfectly for strong heel hold – while Dissociated Lacing with Quicklace means you can tighten the top and bottom of your laces separately for perfect hold. To keep you cool and comfy the top half is made with a water-repellent Aero Membrane. While inside, Live Fit foam instantly moulds to your foot.
