The Marlin Deep model is a lightweight fin for spearfishing and free diving with a replaceable fin. The fins are made of polypropylene and are available in two types of hardness: medium (black), soft (gray). The lightweight slipper is made of thermoplastic rubber with different degrees of hardness. The hard sole increases the transmitted energy, the soft upper part has good elasticity, ensuring ease of putting on and comfort during long use. The angle of the fin relative to the slipper of 22 degrees provides an optimal balance of efficiency and power of movement, reduces the load on the muscles of the lower leg and foot and guarantees a fairly high speed of movement in the water.

Sizes: 39/40, 41/42, 43/44, 45/46, 47/48, 49/50.

Recommendations for choosing a size without using socks:

- If you have a foot size EU44–45, choose size 43–44.

- For example, if you have a foot size of EU39-40 and use 3mm socks, please choose size 39-40. If you use 5-7mm socks, please choose size 41-42.
*The size of the fins also depends on the width of your foot.
