A system and methods for custom-fitting golf clubs and golf club components is disclosed. Data is generated by a tracking device as a plurality of golf swings are performed by an individual. The data comprises motion and orientation information associated with a golf ball and with a golf club. The data is displayed using a graphical user interface. A plurality of shot characteristics is determined from the data. The shot characteristics are used to recommend golf clubs and golf club components that adjust a golfer's swing where the golfer exhibits the plurality of shot characteristics.

A system for optimizing weight distribution of a golf club including a weight receiving grip, the weight receiving grip configured to be affixed to a proximal end of a golf club shaft, wherein the weight receiving grip comprises a generally tubular member comprising a shaft bore configured to surround a proximal portion of the shaft, wherein the weight receiving grip comprises a weight retention portion at a proximal end of the weight receiving grip, the weight retention portion configured to engage a weight member, a grip expanding tool configured to deflect a portion of the weight receiving grip facilitating installation or removal of the weight members from the weight receiving grip.

A golfing level assembly includes a cap that has a brim which extends above a user's line of sight when the user is wearing the cap. A pair of hinges is each disposed on the brim and each of the hinges is positionable in a deployed position or a stored position. A bubble level is coupled to each of the hinges and the bubble level is spaced downwardly from the brim when the hinges are positioned in the deployed position such that the bubble level is positioned within the user's line of sight. The bubble level has a reference line extending along a full length of the bubble level and the reference line is aligned with the visible horizon. In this way the bubble level indicates the degree of slope of the putting green to assist the user with successfully putting on the putting green.

The golf shoe holder with dismountable threaded cleats prevents the supporting foot of a person from moving when attempting to hit the golf ball with a golf club. This is achieved as the holder has two holes with different diameters: the large diameter is to be held between the cleats and the golf shoe sole, by means of the threads that both parts have, and the small diameter is where it holds on to the grass by means of a tee.
