The present disclosure provides an insole, including a base having a front surface for corresponding to the foot sole of a wearer of a shoe with the insole and a rear surface for corresponding to an inner sole of the shoe; wherein the insole further includes a plurality of protrusions evenly arranged on the front surface; the protrusions have the same heights, each protrusion includes a column fixed on the base and a height of the column protruding out from the base ranges from 1 to 7 mm, and a coverage rate of the protrusions on the base ranges from 30% to 70%.

There is also provided a self-sustainable body-cooling garment for cooling a body portion of a human or an animal adapted to use the air pumping footwear and a cooling system for cooling the human or animal's body. There is provided a footwear comprising an air pump adapted to pump air when worn by a human or an animal during a pedestrian movement and to store or direct the pumped air for use by a cooling system for cooling the pumped air and using the cooled air for cooling the human or the animal. There is also provided a cooling system comprising an air pump adapted to be embedded within a footwear and a nozzle adapted to cool air pumped using the footwear when worn by a human or animal during a pedestrian movement.

A healthcare footwear article includes an upper shoe body and a sole member provided underneath the upper shoe body and is connected with the upper shoe body to form an integral body. The upper shoe body and the sole member is configured from a material consisting of approximately 70% to approximately 80% of silicon rubber by weight, approximately 5% to approximately 20% of negative ion powder by weight, approximately 2% to approximately 7% of antiwear agent by weight, approximately 5% to approximately 20% of titanium powder by weight, approximately 0.1% to approximately 1.5% of vulcanizing agent by weight, approximately 5% to approximately 10% of infrared ray powder by weight, and approximately 0.1% to approximately 8% of dye by weight.

A walking-assisted air-jet insole includes an insole base. A plurality of pressed-air outlet units that can generate airflow based on stepping pressure are provided on the insole base; the pressed-air outlet unit includes a cavity for retaining air. An upper part of the insole base is provided with an upper air hole that communicates with the cavity, and a lower part of the insole base is provided with an air sac part that is elastically deformed and restored based on the stepping pressure. A volume of the cavity can be changed based on the elastic deformation and restoration of the air sac part. A lower end of the air sac part is provided with a convex column that moves up and down based on the stepping pressure. The cavity includes an upper cavity portion and a lower cavity portion from top to bottom.

A footwear including a shoe body and a removable, heatable, inner sole is provided. The shoe body is shaped as footwear, for example, in the shape of a shoe, a slipper, a boot, etc. The removable, heatable, inner sole is placed between a sole and an insole of the shoe body. The removable, heatable, inner sole is rigid and is made of a material that can be heated repeatedly in a microwave oven for use within footwear. During use, the user can remove the removable, heatable, inner sole from the shoe body freely and conveniently, heat the removable, heatable, inner sole in the microwave oven, and place the heated inner sole between the sole and the insole of the shoe body. When the user wears the shoe body with the heated inner sole, the user can enjoy a soothing warmth and comfort provided by the heated inner sole.

A method of making an orthotic is disclosed. The method includes the steps of taking measurements relating to a foot and then creating a digital representation of an orthotic on a display device based on said measurements. This digital representation of the orthotic having a heel portion for supporting a heel of a person and a distal portion located in front of the heel portion which can be divided into first and second distal portions. The thickness of the digital representation of the first and second distal portions is then varied such that one of the distal portions is thicker than the other. Finally, an additive manufacturing technique, using a substantially uniform material or materials, is used to create a physical version of the digital representation of the orthotic.
