A piece of snorkelling equipment that may give you a "fishy" feeling (in a good way!), fins make swimming and travelling through the water much easier. Attached to the feet, fins vary in size and help one not only get around, but also lessen the strain on your feet which are constantly moving; this is especially true when you are planning for longer snorkelling excursions which require you to swim greater distances. While fins have been traditionally long in design as used by divers, for snorkelling, shorter fins are generally preferable since they are less in weight and also give you better manoeuvrability. An add-on to this, which can be considered is the use of neoprene socks which will help prevent the forming of blisters on your feet after extensive periods of snorkelling.
