The Seac Vela OH short fins (OH = Open Heel = open foot pocket) reduce fatigue during snorkeling, thus improving the experience at sea. They are easy to wear thanks to the practical rubber strap adjustable in 6 positions. The fit is very comfortable thanks to the soft rubber of the open shoe that holds the tip of the foot firmly. The short blade has grooves that improve water flow and anti-shock rubber edges. Seac Vela OH swimming fins are flexible and resistant and can also be used for swimming training. They are available in 3 colors and 5 sizes to fit from 32 to 47 (XXS/XS: 32-35 | XS/S: 36-38 | S/M: 39/41 | M/L: 42-44 | L/XL: 45-47)
