Presently disclosed grip assemblies provide for a selectively removable and replaceable grip for a shaft. Such grip assemblies include a grip sleeve and a grip liner at least partially fixed to an inner grip surface of the grip sleeve. The grip liner is configured to expand as the grip sleeve and grip liner are positioned on the shaft. The grip liner includes a liner feature that engages a shaft feature, which may be integrally formed on the shaft, or may be formed on a shaft sheath on the shaft. Engagement of the liner feature with the shaft feature may align the grip sleeve to the shaft and may substantially prevent rotation of the grip sleeve with respect to the shaft once the grip sleeve is on the shaft. Presently disclosed grip sleeves may be selectively removed from the shaft without damaging the grip sleeve, and without requiring solvents or specialized tools.

Handles for athletic equipment, such as baseball bats. The handles include two different portions, or sides, each configured to achieve different results. A first portion has a flared shape and no knob, and is configured to interface with the hypothenar side of a batter/user's hand in a way that it promotes the gliding of the handle/knob over his or her hypothenar area, hamate bone and other anatomic areas included in such. A second portion has a least a partial knob and is configured to interface with the user's little finger with a protuberance that engages the little finger, wherein the engagement of the little finger facilitates better grip, a pivot point for proximal part to glide across hypothenar eminence of hand and better performance of the bat (or other athletic equipment) being used.
