Atomic Aquatics X1 BladeFins deliver ultimate power and raw thrust. Firmer, shorter blades and a solid internal frame are attached to power plate foot pockets providing more control and better maneuverability in tight spaces. X1 Blade Fins are perfect for general diving, tech diving and alternate kicking styles like frog and scissor. Taller foot pockets are great for large boots.
