An adjustable clog with a unique strap system is described. The sole assembly for the clog has an interior sole wing situated near a heel of the sole assembly, and an exterior sole wing on an opposite side of the sole assembly from the interior sole wing, near the heel of the sole assembly, wherein the interior sole wing and the exterior sole wing consist of webbing strap and rubber that extend above the sole assembly. The clog also includes an upper, where the upper is affixed to the sole assembly. A wing hook strap is affixed to the interior sole wing on the first end of the wing hook strap and to the paracord loop on a second end of the wing hook strap, wherein the wing hook strap includes a first G-hook that hooks into one of the first plurality of hook pockets. A heel strap connected to the interior sole wing on the first end of the heel strap and the exterior sole wing on a second end of the heel strap through the mechanical ring, said heel strap includes a second G-hook that hooks into one of the second plurality of hook pockets.

The present invention relates to a system integrated or retrofitted to a shoe for preventing a wearer of the shoe from becoming stuck in mud, sand, water, or any other soft terrain while walking. The system includes a pair of tubes positioned on opposing sides of the shoe/boot and a rigid attachment overlapping a portion of the sole of the shoe. A valve having a lengthwise opening can be placed between the rigid attachment and the sole such that each tube of the pair of tubes is attached to opposing ends of the valve using a pair of elbow tubes. Each elbow tube passes through a hole in the rigid attachment to connect to the valve. The valve creates a vacuum when the shoe to which the system is attached is stepped onto the terrain and when the shoe is lifted, the vacuum is released.

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.

Provided is a functional shoe comprising a shoe body, a flipper member extended in a plate shape from an end of the shoe body to be used as a flipper function and deformed upward to be folded so as to cover an upper surface of the shoe body, a fixing part fixing the flipper member, and a strap closely adhering the shoe body to a rear part of a user's foot, wherein the strap is selectively folded or unfolded to adjust a contact area with the user's foot. Accordingly, a shoe function and a flipper function are applied to one shoe to be conveniently used, a contact area with the user's foot may be increased to prevent the shoe from coming off when used in the water, and the strap may be folded to increase convenience outside the water.

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.

Flip flop sandals with a barrier around a perimeter of a sole. The barrier forms a continuous loop, thereby protecting the feet from wind and water in all directions. The flip flops comprise a medial strap, a lateral strap and a toe strap attached to the sole at locations interior to the barrier. The barrier protects the feet from water splashes, puddles, wet grass and wind. The barrier height can be in the range of 0.5-4 inches or 0.7-3 inches. Alternatively, the barrier height can be at least 40% or ½ a length of the toe strap. The barrier can be made of closed cell foam or plastic film. The attachment between the sole and barrier can be water tight.

The present invention discloses a swim fin, including an outsole, a middle sole and a shoe upper sequentially provided from bottom to top; wherein the shape and size of the outsole match the shape and size of a human foot, the outsole is a rubber outsole made of a rubber; the middle sole includes a support part matching the shape and size of the outsole, and a webbed paddling part extending outward along a peripheral of a sole part of the support part; the middle sole is a polyurethane middle sole made of polyurethane; the shoe upper is formed by sewing diving suit fabric; and the middle sole is integrally formed by an upper-containing injection moulding process using the polyurethane, the middle sole is respectively connected to the shoe upper and the outsole during the integral forming process of the upper-containing injection moulding process.
