Articles of sports equipment, such as striking implements (e.g., sticks) and wearable articles (e.g., skates, helmets) for playing hockey or other activities, in which at least one of the characteristics (e.g., stiffness) of the articles of sports equipment is adaptable and can be altered during use of the sports equipment, such as by comprising an alterable component coupled to a controller, by comprising an alterable component that is autonomously alterable, and/or by an alterable component that can be altered in response to a command of a remote device.

A skate boot comprising an outer shell with a heel portion for receiving the heel of the foot; an ankle portion for receiving the ankle, the ankle portion comprising a rear portion for facing at least partially the lower part of the Achilles tendon; and medial and lateral side portions for facing the medial and lateral sides of the foot respectively. The skate boot also comprises a tendon guard extending upwardly from the ankle portion of the outer shell for facing at least partially the upper part of the Achilles tendon, the tendon guard comprising a recess for receiving an insert. The tendon guard has a first flexion mode when no insert is received in the recess and a second flexion mode when the insert is received in the recess. The second flexion mode is different from the first flexion mode.

A sporting good implement, such as a hockey stick or ball bat, includes a main body. The main body may be formed from multiple layers of a structural material, such as a fiber-reinforced composite material. One or more microlattice structures may be positioned between layers of the structural material. One or more microlattice structures may additionally or alternatively be used to form the core of a sporting good implement, such as a hockey-stick blade. The microlattice structures improve the performance, strength, or feel of the sporting good implement.

A boot that attaches to skate chasses for ice skating, roller skating, in-line rollerblade skating, and Nordic skating is disclosed. When disengaged from a chassis assembly, the boot functions as normal footwear for hiking/cycling/leisure activities. To attach to a chassis, a wearer a foot into a boot and then presses the boot into its chassis, engaging a click-in mechanism. Once the mechanism clicks into place, the boot is removably secured to the chassis.

A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

A system, method, and apparatus for replicating the experience of snow skiing on dry land using a roller land ski with an ability to move and stop consistent with mechanics of an actual snow ski. Each land ski includes a rigid platform with a binding for engagement with a specialized boot, a pair of biased omnidirectional casters supporting said rigid platform, but mounted to a top surface of said platform, and a pair of trucks with a plurality of wheels along its curved axles. A pair of specialized boots constructed out of flexible lightweight material with a stiff support structure to fortify a user's foot and ankle from the forces created by the land ski are included in this system. The method includes calibration and selection of materials for both the board and boot in order to achieve the desired experience.

A wearable device configured to selectively provide roller transportation, the wearable device including a shoe, a plurality of wheel assemblies, each wheel assembly being configured to selectively roll relative to a ground surface about an associated axis of rotation, and a frame connected between the wheel assemblies, the frame comprising a trunk and a plurality of branches extending from the trunk, each of the branches being configured for connection to at least one of the plurality of wheel assemblies, wherein at least a portion of the shoe is located vertically higher than at least a portion of the frame when at least one of the wheel assemblies is in contact with the ground surface and the at least one of the wheel assemblies is positioned to selectively roll relative to the ground surface.

A shoe includes: a heel portion; a toe portion; a sole portion; and an electrical assembly. The electrical assembly includes at least: a magnetometer configured to determine a direction of movement of the shoe; and an accelerometer configured to determine acceleration of the shoe. Direction and acceleration data are used to generate a display of a map indicating traversal of a route by a wearer of the shoe at user interface of a user device.
