If you want to step up in snorkeling and go deeper underwater, don’t forget to take the fins designed for diving with you. Lightweight, long-bladed fins, which are faster than short, are the best choice for this occasion. . The fins don't necessarily have to be rigid and wide, it is up to each swimmer to decide which type suits him best. A combination of plastic and rubber is used to make the fins. You can choose from different sizes, with a fully closed corner or a strap fastening (free corner).
