The JET SPORT FULL FOOT is lightweight yet delivers lots of propulsion, excellent maneuverability, plus it feels oh-so-comfy on bare feet. Its slightly stiff blade is a tri-material design featuring a pair of soft rubber panels framed in semi-stiff plastic and flanked by thin side rails, producing just the right amount of flex. There are also drag-reducing vents between the blade and foot pocket to decrease resistance on both up and down strokes. This combination generates propulsive kicking power, provides good stability and makes efficient work of frog and dolphin kicks. The rubber full foot pocket molds comfortably to your foot, and the non-skid pattern is effective on wet decks. A great choice for finning in the tropics.
