The present invention relates to an interchangeable footwear device. The device may include a flip-flop sandal design wherein the device may include interchangeable structural features to allow a user to change features as associated with a particular terrain. The interchangeable footwear device includes a gripping system to traverse a number of different terrains. The footwear may include a sole member having a thong member attached to a top of the sole and a heel strap selectively attached to the sole. The heel strap may be selectively attached to the sole with a fastener that may be manually adjusted in a secured or unsecured position to remove the heel strap from the sole. In particular, the interchangeable footwear device may include a gripping unit selectively attached to the sole member of the footwear. The gripping unit may include a toe grip pad and a heel grip pad.

A swim or scuba diving fin includes an open-back shoe portion having a pocket for receiving the foot of the user and no heel portion, a blade portion forming a forward extension of the shoe portion, and an element holding the foot in the open-back shoe portion, includes an elongate element in the form of a strap, belt or the like and a length sufficient to surround the heel portion, the sidewalls of the pocket of the shoe, and at least part of the tip of the shoe. Such elongate element is at least partially separated from the open-back shoe portion, and is or may be connected to the open-back shoe portion (3) in length-adjustable and/or at least partially removable fashion through first coupling members, which engage corresponding second coupling members located at the front tip of the open-back shoe.

A flexible shoe includes an under sole, a foot bed, a first over-foot portion, and a second over-foot portion. The under sole is formed of ballistic nylon. The foot bed is arranged on an upper surface of the under sole. The first over-foot portion is attached to the under sole and is configured to flexibly overly an instep of a foot of a user forward of an ankle of the user. The second over-foot portion is configured to flexibly wrap around a heel of the user rearward of the ankle of the user and includes a tab extending toward and coupled a heel portion of the under sole. The under sole, the first over-foot portion, and the second over-foot portion define a cavity configured to enclose the foot of the user. The foot bed is positioned entirely within the cavity.

The invention relates to a one-piece sandal (1) injected in a single piece with a strap (2) placed on the side of the sole (3S), particularly non-slip, and of the insole (3P), particularly anatomical, however with freedom of rotation towards the front hook (4) where the male fitting (5) engages with the female fitting (6) of the strap (2), forming the strip in the format of the instep, thus providing a product having an innovative assembly concept, with non-slip sole and comfortable insole.

A watersports sandal is disclosed. The sandal has a flexible sole that underlies and protects a user's foot in a walking configuration. The sandal has a detachable forefoot strap that connects the sole to the user's forefoot and an ankle strap that connects the heel portion of the sole to the lower leg of the user. The sandal can be reconfigured to a stowed configuration in which the forefoot strap attaches the sole to a user's lower leg. In this stowed configuration, the user's bare feet are exposed to allow him fine sensitivity to water sport devices such as surf boards.
