The Master Frog is not "new" but in my view is one of the best all around fins made for SCUBA. Cressi took their freedive blade, with its sharp snappy material, shortened it and widened it for scuba use. The fin has a large surface area, is very light, and has a very strong snap. Loads of power when needed, delicate maneuvers when those are called for. Far and away, to me, better than the heavy vented fins (never saw the point in fins with holes or vents--aren't fins supposed to move water?). They are superb at all kicks, flutter, frog, helicopter and backwards because they have thin blades with no side "rails" or other bumps, struts, or other gizmos, so they sideslip effortlessly. All that is needed is to replace the straps with spring or bungee straps.
I am going to be comparing these to Exellerating Force Fins very soon, so will report on that.
