Fins
By using fins we get effective propulsive power in the water, since we don’t use our hands in order to keep them free for other tasks. Easily removable strap-type and easily motile full boot-type fins are used. Materials for the blade include rubber, lightweight plastics, and urethane. It is important to choose your fins carefully for what suits you best, as there is a variety of styles. In general, flexible blades are preferred over hard blades by beginners.
