<p>A first flipper has a base, a deformable fin connected to the base, and a first spreader that imposes a first force on the fin that causes the fin to spread in response to relative movement between the first spreader and the fin caused by a first longitudinal deflection of the fin relative to the base. A second flipper has a fin and a foot coupling portion connectable to a foot holding portion of a boot to couple a foot in the foot holding portion to the flipper. A first system includes the flipper and the boot. Methods of using the flippers, the boot, and the system are also disclosed.</p> |
