Swim fins are very personal. Our toes, feet and ankles vary widely. A good swim fin for one person is a terrible swim for another person. We range from short and wide to long and narrow and everywhere in-between. Some fins are very rigid and other soft, some blades are stiff and others very flexible. Finding a good fit is important. If the fin does not fit well your feet and legs will cramp regardless of how well the fin might propel you through the water. Some fins float, some don't. Some are light and others are heavy.
