Ski boot comprising a rigid shell which is shaped so as to accommodate the foot of the user, and has a lower part structured to couple with a ski binding device; a rigid cuff which is shaped so as to surround the lower part of the leg of the user, and is pivotally jointed to the shell thus to be able to pivot about a rotation axis substantially perpendicular to the midplane of the boot, and shell closing means adapted to selectively tighten the shell on the foot of the user; the shell comprising a substantially basin-shaped casing which is superiorly provided with a main opening from which the leg of the user comes out, and with a longitudinal slit that branches from said main opening and extends along the casing towards the front tip of the shell; the shell closing means being placed at the longitudinal fissure.

A disposable waterproof bootsock is worn over foot and sock to protect from exposure to liquids, dirt and other contaminants in an environment that can penetrate footwear or reach above the ankle. The bootsock is secured about the wearer's calf and ankle using fasteners that accommodate a range of calf and ankle sizes and allow adjustment to the wearer's desired fit while maintaining the bootsock in position upright. One or more sealed compartments are provided to hold essential supplies.

An article of footwear with adjustable stiffness is provided. The article of footwear in the form of a snowboard boot is provided with adjustable tensioning systems that are disposed on either side of an inner liner of the snowboard boot. The adjustable tensioning system includes a comb body structure having flex portions made of a plurality of extending fingers with a flexibility that can be controlled by the adjustable tensioning system. Depending on the level of tension applied by the tensioning system, or lack thereof, a range of flex profiles having varying amounts of stiffness are available to the wearer to adjust the overall stiffness of the snowboard boot.

A liner for sports shoes includes a sole, an upper to which is associable at least one deformable hollow insert, adapted to custom fit the liner to a user's foot. Specifically, in the deformable hollow insert a plastically deformable filler material is injectable at room temperature in a reversible manner by applying an injection pressure of a device. Moreover, the plastically deformable filling material is suitable to be suctioned, at room temperature, with the device from the deformable hollow insert applying a suction pressure.

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 sports shoe, including a sole and an upper that rises up from said sole, wherein the upper includes an inner part or core, in which the sports shoe and/or the inner part or core has an inner housing volume (RZ) for a foot of a user defined, during use, by an inner surface of the upper and by an inner surface of the sole and/or by the inner volume of the inner part or core, positioned inside the upper, including an upper-shaped portion and a ground resting portion, the latter adapted to come into contact with the ground or with the inner surface of the sole.

There is disclosed a ski boot system. One embodiment includes right and left side portions formed by a longitudinal split with a hinged connection therebetween. The open configuration allows placement of an inner liner into the shell. The closed configuration restricts removal of the liner from the shell. A selectively fastenable connector and/or a selectively locking sheath extend between the right and left side portions. The selectively fastenable connector and/or the selectively locking sheath permit selective positioning of the shell between open and closed configurations. The liner of a ski boot includes a wall of material defining inner and outer surfaces. The outer surface defines an exterior having dimensions sized to compressively fit within the shell. The inner surface defines an interior having dimensions sized to receive a foot. Other embodiments are disclosed.

Ski boot with rigid shell comprising a lower shell (30) and a cuff (20) articulated in rotation to the lower shell (30), characterized in that it comprises at least a connecting ring (10) connecting the cuff (20) to the lower shell (30), this connecting ring (10) comprising a locking surface (11) collaborating with an opening (31) in the lower shell (30) so as to prevent the connecting ring (10) from rotating relative to the lower shell (30), and a rotation surface (12) collaborating with an opening (24) in the cuff so as to guide the rotation of the cuff (20) relative to the lower shell (30) about this second surface.

Comfort element (1) for a sports shoe innerboot, comprising at least one thermoformable foam having at least two zones of different thickness and forming at least one face of the comfort element with zones (4 to 8) in relief, which is able to form at least part of a layer of the wall of a sports shoe innerboot, characterized in that the product of the thickness times the density of the comfort element (1) differs between these at least two zones of different thickness.

A sock and/or outer footwear having one or more portions with reduced frictional characteristics. One or more of the heel portion, the arch portion and the ball portion of the sock and/or interior of the outer footwear is fabricated with one or more fibers having the reduced frictional characteristics. The reduced frictional characteristics are established with the one or more low-friction fibers that are integrated with fibers having additional complementary characteristics of thermal regulation and moisture management. The provision of reduced frictional characteristics in one or more of the heel, arch and ball facilitates insertion of a foot into footwear.
