FCS Soulflex 8 Clear Longboard Fin
FCS Soulflex 8 Clear Longboard Fin. FCS Soulflex Longboard Fin flexes further down toward the base, livening up the board, making it more responsive. Similar to a traditional dolphin outline, but smaller in area from base to tip allowing less resistance when entering and exiting turns. Performance Glass material characteristics and flex pattern are identical to traditional fiberglass fins. Performs well in progressive longboards with side fins, single fins up to 6`6, and 5 fin boards with a center fin box.
