A golf club head has a cast cup including a forward portion of a crown and a forward portion of a sole of the golf club head. A polymeric rear ring is coupled to heel and toe portions of the cast cup to form a club head body defining a crown opening and a sole opening. A crown insert is coupled to the crown opening, and a sole insert coupled to the sole opening. The club head has an inertia generator including an outwardly extending protrusion formed in the sole and a rear weight positioned at an aft end of the protrusion, the sole insert defining at least a portion of the protrusion of the inertia generator. The sole insert includes a composite material having a thickness between 0.45 mm and 1 mm, and a plurality of ribs positioned along an internal surface, and at least one rib is inside the inertia generator.

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.

A footwear piece having an open heel and toe-post is described. The footwear piece, which may generally be in the form of, e.g., a clog, includes a sole portion and an upper portion extending over the front portion of the sole portion to form and define a toe box region. A toe-post extends through the toe box region from the sole portion to the upper portion. When in use, the toe-post may reside between the grand toe and index toe of a user. The footwear piece is free of any type of heel restraint mechanism, include a heel restraint mechanism that is moveable, pivotable, or removable. The footwear piece may be made from lightweight foam material.

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. The channel may have a cross-sectional profile that is asymmetric with a front wall and a rear wall where the front wall is longer than the rear wall. The channel may also have a center thickness that is different than a thickness at the heel and toe sides.

The invention relates to the related technical field of shoemaking, in particular to a compacting machine for shoemaking based on flexible extrusion and a compacting method.The compacting machine comprises a workbench and a side plate fixed to the workbench, and the upper portion of the workbench is arranged in a U-like shape; two pressing blocks are movably arranged on the working table, the two pressing blocks are oppositely arranged, arc-shaped notches are formed in the opposite sides of the two pressing blocks, a shoe is arranged between the two pressing blocks, and the two pressing blocks can be driven by opposite driving mechanisms arranged on the working table to move towards a heel and a toe cap respectively; under the pressure of the air cylinder, the multi-section telescopic structures in the unfolded state can apply pressure to the two ends of the shoe sole respectively, the effective positioning function of the shoe is achieved, and the problem that when the pressure applying blocks apply pressure to the two ends of the shoe subsequently, the toe cap position is prone to warping is solved; and the problems of non-uniform pressure distribution, local underpressure or virtual adhesion and the like of the vamp and the sole in a key bonding area are avoided, and the strength and the consistency of pressing and bonding are seriously influenced.
