Express fins open a new way for the future generation of the full-pocket fin. Large blade moulded in extra flexible material. The elastic rubberized zone in the full-foot tip allows the blade to bend obtaining the optimum flexibility.
Once loaded with energy on the power stroke, the special full-foot tip zone will release the energy prior to the upstroke to provide an added boost of power - Patent Pending.
The strong rubber side ribs increase performances and lengthen the life of the fin.
Express own large non-skid rubber patches.
