Minimal blades are made of 100% fine texture twill T300 carbon fibre for smooth, efficient finning. This means less energy used and longer bottom times. They are well proportioned and made to be used with C4 400 foot pockets. These foot pockets feature a low-volume design, intended to reduce drag and compliment the efficiency of the fin blades. Their close fit to the foot means you aren't wasting energy on empty space in the foot pockets or experiencing drag from water filling the foot pocket space.
