A shoe has a main body, an ankle strap, plantar bridge, and a toe loop connected to the main body. The main body wraps around the dorsal instep area of the foot and the plantar bridge wraps around the plantar midfoot area of the foot, without covering the ball, the plantar metatarsals, the heel, or the toes. The ankle strap is attached at its ends to the main body and extends around the back of the foot above the heel for constraining the main body from forwarding movement. The toe loop surrounds one of the toes and connects with the main body from above the foot, for constraining the main body from rearward movement.

A swim fin for wearing on a foot features lateral and medial side fins which do not extend further forwardly past a front end of a shoe portion of the swim fin, which forms a receptacle for receiving the foot. Also, the side fins are spaced from a sole of the shoe portion and located closer to an upper of the shoe portion than the sole.

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.

An article of footwear configured for prolonged casual and non-casual uses having an upper configured for easy installation and removal of the article of footwear with or without the use of fasteners, a sole, and a substantially continuous series of alternating ribs and grooves on a footbed of the sole extending from a forefoot region to a heel region. The ribs and grooves have base widths that are greater in an arch region of the footbed than the forefoot and heel regions of the footbed. The series of alternating transverse ribs and grooves are oriented from a lateral side region of the footbed to a medial side region of the footbed.
