The present invention provides for a hockey pads system construct an arranged with an upper base pad and lower base pad each of said race pads configured to secure one or more sizing pads there between.

An athletic sock for athletes, or those seeking to increase their athletic performance, to reduce the likelihood of lateral-extension ankle sprains and foot and leg cramps, and to reduce the likelihood of aggravating or bring relief from plantar fasciitis. The sock will additionally increase an athlete's vertical jump height and lateral foot speed. The sock enacts tensions on the foot at specific locations causing the foot to dorsiflex. The sock incorporates elastic material from the balls of the feet to an area ranging from the instep to above the ankle to provide tension for dorsiflexion. Elastic material is placed around the ankle and heel for support and protection while maintaining tensile strength that does not inhibit easy application of the sock or the foot's range of motion. Elastic material can be added around the arch of the sock to further reduce the aggravation of, or bring relief from, plantar fasciitis.

An Internet of Thing (IoT) device includes a transceiver coupled to a processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A protector for protecting a skate (e.g., an ice skate) and a foot of a user (e.g., a hockey player) against impacts, such as from pucks (e.g., during shots, which can be powerful), to reduce risks of pain or injury from such impacts, in which the protector is fastenable to the skate, is configured to cover at least part of a skate boot of the skate, and may be designed to facilitate its use, including by facilitating the user donning (i.e., putting on) and doffing (i.e., removing) the skate (e.g., while the protector is fastened to the skate boot), and/or to look like the skate boot (e.g., so as to be relatively unnoticeable such that it can seem as if it is not there).

Provided is a joint protection device, including a joint protection body whose longitudinal and horizontal shapes match a shape of a joint, joint protection body being an integrally formed rigid hollow housing with an opened bottom and including a front supporting portion and side supporting portions respectively wrapping a front surface and side surfaces of joint to provide front and side support for joint; at least one notch being provided in a portion, close to a joint movement area, of joint protection body, and dividing joint protection body into a plurality of joint pieces; adjacent joint pieces being connected by two local junctions respectively provided at appropriate positions on two sides of joint protection body, and capable of rotating with local junctions as rotation fulcrums; and when joint pieces rotate around rotation fulcrums to a limiting position, adjacent joint pieces coming into contact with each other and stopping rotating.

A protective boot assembly for protecting feet and legs during combat sports includes a pair of boots. Each of the boots is worn during combat sports thereby facilitating a foot and a shin to be protected when receiving kicks and when delivering kicks. Each of the boots has a substantially open sole and an open calf.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

Hockey goalkeeper leg pads wearable on legs of a hockey goalkeeper to protect the legs, in which the hockey goalkeeper leg pads may be configured to enhance performance, comfort and/or other aspects of goalkeeping of the hockey goalkeeper, including when the hockey goalkeeper leg pads drop onto a playing surface (e.g., ice) to lie substantially horizontally on the playing surface with their front facing play (e.g., as in a butterfly position or otherwise).

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

The present invention concerns a hit detection equipment, usable by a fighter and an opponent for martial arts such as taekwondo, karate or boxing, comprising a central device, a valid surface, for example a jersey and/or a helmet, and at least one authorized surface, for example a glove and/or a shoe. Said valid surface comprises at least one conductive surface and said authorized surface comprises two conductive structures insulated from each other, intertwined with each other over the entire said authorized surface, and each connected to an electrical terminal, and configured so that a contact of said authorized surface on a conductive surface creates a short circuit between the two conductive structures.

The present invention also concerns a method for detecting a hit struck by a fighter on an opponent, for martial arts such as taekwondo, karate or boxing, each equipped with an equipment according to the invention.
