Shorter than most top-line full-foot fins (less than 21 inches) and very lightweight (1 pound, 5 ounces for a size regular), the Accel gives fans of open-heel fins the best of both worlds: the comfort and adjustability of an open-heel fin, with the weight, size and performance of a full-foot fin. While also good for local diving, you won’t find a better open-heel travel fin.
