Scubapro Jet Sport Dive Fin

FGSS lists the Scubapro Jet Sport Dive Fin here as an Amazon-affiliate pick from Scubapro. Big, slightly stiff 3-material blade for propulsive power. Drag-reducing vents cut resistance on up/down strokes. That's there to cut resistance on the recovery kick, so your legs aren't fighting the water on every stroke. This one's an open-foot-pocket design rather than sold by a specific numeric size -- if wide feet have made off-the-shelf fins uncomfortable before, that adjustable strap system is worth knowing about going in. FGSS doesn't stock this one ourselves -- it's an Amazon-fulfilled listing, and as an Amazon Associate we earn a small commission if you buy through it, at no extra cost to you.
