This invention belongs to the field of medical device technology and discloses a foot pressure relief device for diabetic foot. It includes a base, a pressure relief plate and a motor connected to the base, and a foot pedal and a transmission assembly connected to the pressure relief plate. The transmission assembly includes a crank, a first connecting rod, and a sliding seat. The crank is fixedly connected to the output shaft of the motor, and the sliding seat is connected to the pressure relief plate. The two ends of the first connecting rod are respectively connected to the crank and the sliding seat. The sliding seat is connected to a foot rolling shaft and a second connecting rod, and the second connecting rod is connected to a foot massage roller. A buffer spring is provided between the pressure relief plate and the base. The foot pedal has a through groove, and the foot rolling shaft is connected to a foot massage roller. This invention utilizes the foot rolling shaft / foot massage roller and the foot massage roller to simultaneously perform rolling massage on the sole and instep of the foot. The periodic oscillation of the pressure relief plate causes the heel and toes to alternately rise, resulting in good pressure relief for the foot.

This disclosure relates to golf club heads. A casting cup may include a front portion of the golf club head, comprising an insert, a face portion, and a front portion of the crown, a front portion of the sole, a front portion of the heel, and a front portion of the toe. A rear ring may be formed separately from the casting cup and attached to the heel and toe portions of the casting cup to form a metal club head body, such that the club head body defines a hollow internal region, a crown opening, and a sole opening. The casting cup and rear ring may be cast from a titanium alloy. A composite crown insert and sole insert may then be attached to the crown and sole openings. The face portion of the casting cup may have a desirablely complex geometry. The rear surface of the face portion of the casting cup may be modified before the rear ring is attached.

A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball and a channel extending across a portion of the sole. The channel may be recessed from adjacent surfaces of the sole and have a depth of recession from the adjacent surfaces of the sole, wherein the channel comprises a center portion extending across a center of the sole, a heel portion extending from a heel end of the center portion toward the heel, and a toe portion extending from a toe end of the center portion toward the toe, wherein the width and the depth of the center portion of the channel are substantially constant, and wherein the depth of the channel is greater at the heel and toe portions than at the center portion.
