A method of coupling a boot toe body to a fin apparatus is disclosed. The fin apparatus includes a fin body coupled to a boot coupling body. The method involves connecting a first boot connector on a first end of the boot coupling body to a first complementary boot connector on a top side of the boot toe body, and connecting a second boot connector on a second end of the boot coupling body to a second complementary boot connector on a bottom side of the boot toe body. Boot toe bodies, fin apparatuses, and systems including the boot toe bodies and fin apparatuses are also disclosed.

A configurable wearable apparatus for water sports includes a boot and a fin pivotably attached to the boot. In a first configuration, the fin is oriented towards the toe portion of the boot. In a second configuration, the fin is oriented towards the heel portion of the boot. The fin can be attached to the boot by rods having first and second ends. The first end of each rod is attached to the fin and the second end of each rod is attached to a pivot point on the side of the boot. The second end of the rods can be releasably secured to the toe portion or to the heel portion of the boot with press-fit or friction-fit assemblies.

A disclosed diver fin includes a blade and a foot pocket, distinct from one another and releasably connected to one another by one or more rails extending from a leading edge of the blade to the foot pocket. The rails extend from either side of the foot pocket and extend parallel to one another at least partway along the length of the blade towards a trailing edge of the blade. Each rail includes two sections: a first rail section, extending from the leading edge of the blade and terminating in a free end, and a second rail section, extending from the foot pocket and terminating in a free end. The free end of one rail section includes a female recess, and the free end of the other rail section terminates in a male extension, slidably receivable in the female recess. The disclosed fin is reconfigurable to accommodate different diving conditions.

The present invention extends to apparatuses and methods directed to a modular and adjustable swim fin. Some aspects of the invention include a swim fin having one or more interchangeable fin ribs that facilitate adjustment of flexibility characteristics of the swim fin. For example, interchangeable fin ribs having different flexibility characteristics (e.g., durometer, stiffness, rigidity, or hardness) provide desirable performance when attached to a fin blade of a swim fin. In addition, some aspects of the invention include a fin blade with an adjustable fin split that facilitates use of either a solid fin blade when the adjustable fin split is closed or a split fin blade when the adjustable fin split is open.
