A ski boot adjustment system includes an adjustment mechanism which tightens and loosens a portion of a ski boot, a triggering device that selectively actuates the adjustment mechanism, and a controller that monitors pressure in the portion of the ski boot during operation of the adjustment mechanism. A user can use the triggering device and adjustment mechanism to customize the fit of the ski boot in different regions thereof. The adjustment mechanism can include air bladders, automated motorized straps, or other tightening features. The triggering device can be a manually operated trigger on the ski boot or a remote computing device in wireless communication with the controller, such as a smartphone operable by the user, a transmitter within a ski mat onto which the user steps, or another form of transmitting device.

The invention provides a shell including a left portion and a right portion which are able to switch between a translation open state in which they are separated from each other by a distance and a closed state in which they are closed with each other, wherein in the translation open state, the left portion and the right portion are able to pivot relative to each other, wherein the shell also includes a locking mechanism and a separation bias device, wherein the locking mechanism is configured to keep the shell in the closed state and is able to be released so as to allow the shell to be placed in the translation open state, and wherein the separation bias device is configured to bias the left portion and the right portion toward the translation open state.

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 method and apparatus for generating thermal energy (heat) from human locomotion is proposed and used to provide heating of the user's footwear. The apparatus takes the form of a pair of flexible, liquid-filled chambers connected by an energy-generating tube. One chamber is located in the heel region of a footwear insole, with the other in the toe region, such that as a person walks, the liquid moves back and forth within the tube. This movement is used to also move an energy-producing element (either an electromagnetic arrangement or viscous liquid) back and forth within the tube and convert the captured human locomotion energy into thermal energy, thus warming the footwear.

The present invention relates to a shoe, and in order to provide a shoe excellent in convenience, easy to put on and take off, inexpensive, light-weight, comfortable to wear, promoting health and exhibiting excellent extensibility, the easily wearable shoe according to the present invention is characterized by the shapes of an outer layer and inner sacs corresponding to various body organs, additionally including a shoe outer layer, sacs of a stretchable material joined mainly inside the outer layer, and an intake inlet/outlet that is formed of a valve that takes in and discharges an air-like gas into/from the sacs, facilitating the insertion of a foot by injecting the gas from the intake inlet/outlet into the sacs and causing the sacs and the shoe outer layer to be flexible, discharging the gas from the intake outlet so as to cause the shoe outer cover and the sacs to contract and come into close contact with the foot, being capable of freely setting an effect from the shoe on a body organ due to the shapes of the outer layer and the inner sacs corresponding to various body organs, and being capable of effectively extending the functions of the shoe.

A method for manufacturing a massaging shoe comprises: during the manufacture, preparing a shoe sole (10) firstly, wherein the shoe sole (10) includes a shoe sole body (11) having a containing cavity and a top board (12) arranged on the shoe sole body (11), and a controlling element assembly (60) is arranged in the containing cavity; preparing a shoe vamp (20), wherein an inner side of the shoe vamp (20) is provided with an interlayer; preparing a first massaging air bag (30), a second massaging air bag (40), and a third massaging air bag (50); securing the shoe vamp (20) onto the shoe sole (10) to form a sole body, arranging the second massaging air bag (40) on the top board (12) in the shoe body, arranging the first massaging air bag (30) and the third massaging air bag (50) in the interlayer of the shoe vamp (20), and communicating the three massaging air bags with the controlling element assembly (60). In the method of the present invention, when assembly the shoe vamp (20) and the shoe sole (10), since there is no massaging air bag in the shoe vamp (20), the assembly between the shoe vamp (20) and the shoe sole (10) is more convenient and easier, such that the manufacturing process of the massaging shoe is simplified, and the massaging air bag is prevented from being damaged, thereby improving the yield rate; moreover, both assembly and disassembly of the massaging air bag are convenient, and it is also convenient to clean and repair the massaging shoe.

An inflatable wading boots including a boots assembly and an inflatable assembly. The boots assembly includes wading boots integrated to waders. The inflatable assembly includes a bladder, and a bulb. The bladder is an inflatable bladder. The bulb is an air pump. The bladder is connected to the pump. The bladder and the pump are mounted to each of the boots. The bladder is inflated to secure the boots to the feet of a user preventing the boots from getting off of the feet. The waders has bladders at a waist portion, a back portion and shoulder portion to inflate and prevent sinking.
