These boots are deigned to be used with open heel fins. They are made from soft, double-lined neoprene and have a practical zip from the sole to the ankle, making them easy to slip on and off. Water seepage is reduced to the minimum thanks to a thin flap seal under the zip, which acts as an effective barrier against any water that may seep through the zip. Strong non-slip moulding covers the entire sole. Reinforcements on the back of the foot and the heel provide protection against wear and tear. They are made in three thicknesses: 3 mm, 5 mm and 7 mm Sizes: XS, S, M, L, XL.
