This monfin is made by Waterway Fins and is our #1 seller. It has full foot pockets which means that you can comfortably wear it for many hours at a time. It is a great fin for both beginners and more advanced Freedivers. Our own Mandy-Rae Krack wore this fin for her first Constant Ballast World Record so don’t think you will be limited by it in any way! It comes in several footpocket sizes (they fit big) as well as in Soft/Long Distance (better for pool training), Medium (the chose of most depth divers), or Hard (this one is very stiff).
