A motorized shoe assembly includes an electronic device, such as a smart phone or the like, that is carried by a user. A shoe is provided and the shoe is worn on the user's foot, and the shoe has a sole and a heel. A first roller is rotatably coupled to the sole of the shoe for rolling on the support surface. A second roller is rotatably coupled to the sole of the shoe and the second roller is aligned with the heel. Moreover, the second roller is spaced upwardly from the support surface when the sole rests on the support surface. Alternatively, both of the first and second rollers engage the support surface when the shoe is tilted rearwardly onto the heel. A motor is positioned within the shoe and the motor is in mechanical communication with the second roller. The motor rotates the second roller when the motor is turned on to urge the user along the support surface.

Athletic shoes may include a blade runner that may aid a wearer with speed and/or jumping. The blade runner may be an extension below the sole of the athletic shoe that may function as a lever. Inclusion of this extension may allow the wearer to run with enhanced speed and/or may improve the height and/or distance that a wearer may jump. The extension may be formed of carbon fiber and/or a composite material capable of withstanding extreme stress tolerances that may be associated with running and/or jumping. A cap may be attached to a leading edge of the extension to allow for greater traction.

Systems and methods are described for providing coaching, training, or equipment specification information to individual golfers based on data generated during their individual golf swings. Additionally, data hubs are described that provide information and services to individuals based on data collected for a community of multiple golfers. Such community data hub systems and methods may provide one or more of the following: (a) storage of scoring data, swing data, ball flight data, and/or equipment data for multiple golfers; (b) at least some level of individual access to the stored data for the community; and/or (c) electronic interaction between golfers within the community.

A method for producing of a foot part for a sports shoe includes the steps of producing a flexible forming part for the shoe collar and shoe sole of the foot part, and joining the edges of the forming part along the shoe sole and around the toe cap. In addition, a foot part for a sports shoe and a sports shoe are provided. The foot part for a sports shoe includes a flexible forming part having edges joined along shoe soles and around a toe cap. The sports shoe includes the foot part.

A skate (e.g., an ice skate) for a skater (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the skater and a skating device (e.g., a blade and 5 a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). At least part of the skate boot and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate (or other 0 footwear) to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured. Other articles of footwear are also provided.
