AQUA-SPEED INOX FINS blue-gray 11 Modern, comfortable, flexible full-boot fins designed for snorkeling and easy, recreational diving.
They fit perfectly to bare feet. The fins are very easy to put on and take off.
They have holes that reduce the load on the fin blade during acceleration.
The appropriately shaped center of the fin creates a tunnel that directs the water flow backwards, thereby increasing thrust and swimming speed and reducing leg fatigue.
