In one example, a ski boot dynamic support strap includes a band configured to be connected to a ski boot, and a restraint element configured to be connected to the band. The restraint element includes a wall having an upper edge, and a lip that is connected to the upper edge of the wall and extends away from the wall. The lip and the wall collectively form an engagement portion that includes an undercut area, and the engagement portion is sized and configured to accommodate a portion of an upper edge of a tongue of a ski boot liner in the undercut area.

A footwear assembly includes a shoe having a vamp and an outsole. The shoe includes a first room defined between the vamp and the outsole, and a first opening is formed in the top of the shoe and communicates with the first room. A first connection member is located on outside of the first opening. A water-proof sock is inserted in the first room via the first opening, and has a neck portion formed along the second opening of the water-proof sock. The neck portion is able to be foldable relative to the water-proof sock and has a second connection member which is connected to the first connection member when the neck portion is foldable relative to the water-proof sock.

A footwear construction is provided including a primary footwear component and a secondary footwear component removably disposed in the primary footwear component. The primary footwear component can include an inward facing wall, and the secondary footwear component can include an outward facing wall surrounding a secondary sole of the secondary footwear component. The inward facing wall is configured to releasably interlock with the outward facing wall, such that the secondary sole is secured within the primary footwear component, yet can be manually pulled upward, whereby the inward facing wall releases from the outward facing wall to enable the secondary footwear component to be removed completely from the primary footwear component.

A walking boot and a boot frame. The boot frame can be formed to receive the walking boot. The walking boot can be secured within the boot frame via one or more buckles. The walking boot can have an externally mounted tongue that can be tensioned via the use of one or more laces and associated tensioning mechanisms. The tongue can be molded to conform to a user's foot and leg while the tensioning mechanisms secure the user's foot and leg within the walking boot. In some embodiments, the boot frame has an open heel to capture the walking boot. In some other embodiments, the boot frame has a rotatable heel configured to pivot away from the toe and receive a heel of the walking boot for easy coupling of the walking boot to the boot frame.

A ski boot assembly may include an outer shell having a relatively hard portion and a relatively soft portion. A cuff may be attached to the hard portion for pivot action relative to the outer shell. The cuff may extend around the outer shell, leaving an instep cover of the soft portion exposed. The cuff may include overlapping portions that are hinge coupled to the cuff. A flex bar may be inserted into a shaft of the hard portion. A bootboard may be situated above the sole plate, and be provided with ridges. A shoe can be inserted into the outer shell. The sole of the shoe may be provided with grooves that receive the ridges of the bootboard. A locking mechanism can be mounted on the hard portion of the outer shell to selectively engage with the heel of the shoe.

A shoe includes an outsole and a vamp, and a first opening is defined in the top of the shoe. A first connection portion is located along the periphery of the first opening. A water-proof sock is inserted into the first opening and has a second opening defined in the top thereof. A second connection portion is formed at the periphery of the second opening. The first connection portion is detachably connected to the second connection portion to secure the water-proof sock to the shoe. The water-proof sock can be removed from the shoe by separating the first connection portion from the second connection portion.

An exoskeletal boot is provided. The exoskeletal boot can have a walking boot and a boot frame. The boot frame can be formed to receive the walking boot. The walking boot can be secured within the boot frame via one or more buckles. The walking boot can have an externally mounted tongue that can be tensioned via the use of one or more laces and associated tensioning mechanisms. The tongue can be molded to conform to a user's foot and leg while the tensioning mechanisms secure the user's foot and leg within the walking boot. In some embodiments, the boot frame has an open heel to capture the walking boot. In some other embodiments, the boot frame has a rotatable heel configured to pivot away from the toe and receive a heel of the walking boot for easy coupling of the walking boot to the boot frame.

[Problem] To provide a sports inner boot that ensures removal from a sports outer boot to allow an inside to be easily washed and where a drying time be a comparatively short time.

[Solution] A sports inner boot made of a thermoplastic plastic includes a bottom plate 10 disposed in the sports outer boot and a foot wrap portion 20 formed at the bottom plate 10. The bottom plate 10 and the foot wrap portion 20 are integrally formed. The bottom plate 10 and the foot wrap portion 20 contain an ethylene vinyl acetate copolymer material (EVA).

A hard-shell boot comprises a boot liner and an outer shell having an accommodation space for accommodating and positioning the boot liner. Two sides of a top portion of the outer shell respectively have a first flank portion vertically penetrated by a first-through-hole and a second flank portion vertically penetrated by a second-through-hole. A connecting member comprises an inner-blocking-piece located in an inner side of the top portion of the outer shell and an outer-blocking-piece. One end and the other end of the inner-blocking-piece respectively have a first-engaging-portion connected to one end of the outer-blocking-piece by passing upward through the first-through-hole and a second-engaging-portion connected to the other end of the outer-blocking-piece by passing upward through the second-through-hole. Thus, the width and size of the hard-shell boot can be adjusted simultaneously to facilitate the use of users with different foot widths and sizes.
