Advanced training fin. Made of high-grade polypropylene. The HEAD team designed an exclusive training fin to assist the development of a powerful kick and stronger propulsion. Improves technique and strengthens the muscles. Closed foot pocket for a secure and comfortable fit.

Size 40/41 is too short for size 41. Size 42/43, on the other hand, is too big for size 41. So with size 41 I can neither use the smaller nor the larger fins.
The weight is lighter than that of other fins. After testing the Head Swim Fin Energy and a pair from Decathlon, I found the slightly heavier pair from Decathlon to be more comfortable and less strenuous in terms of weight.
