The bottom surface of the outsole includes a forefoot bulge and a heel bulge which provide the footwear with controlled instability for providing dynamic conditioning of the wearer's muscles during the gait cycle.

A hollow golf club head comprises a face portion whose front face defines a club face for striking a golf ball, a sole portion intersecting the club face at the lower edge thereof, at least one groove being provided on an outer surface of the sole portion, the groove extending in a v-shaped formation whose corner portion is smoothly bended and protrudes toward a leading edge of the head, the groove having a ratio (W/L) of a length w in its front-rear direction to a length L in its toe-heel direction being from 0.20 to 1.50 at least partially, and a distance between the leading edge and the corner of the groove being in the range. of from 5 to 30 mm in the front-rear direction.

A projectile having improved accuracy when fired over long ranges is formed from a monolithic block of a copper alloy. Proceeding from a nose to a heel of the projectile, is a fore portion with arcuate side walls, a body portion of substantially constant cross-sectional area that minimally contacts a rifled gun barrel, a drive band having a diameter effective to seal propellant gases and an aft portion that continuously decreases in diameter terminating at the heel. A cylindrical bore extends from an opened end at the nose to a closed end proximate to a transition plane between the fore portion and the body portion.

A cavity back golf club head having a bridge member and a damping element is disclosed. The bridge member extends across a first rear cavity connecting a heel and a toe of the golf club head to control the trajectory of a golf ball. For the longer iron clubs, a damping element extends from the sole portion of the cavity back golf club head to the bridge member to define a second cavity to further influence the trajectory of the golf ball. For the shorter iron clubs, the damping element extends from the top portion of the cavity back golf club head to the bridge member. The damping element may reduce the vibration and sound of the golf club head upon impact with a golf ball.

A midsole for footwear comprising a midsole element, which comprises a top plate, a bottom plate, and a plurality of strut members disposed between the top and bottom plates for supporting the top plate a distance away from the bottom plate. Adjacent strut members have a C shaped cross-section facing in the same direction. The midsole element may further comprise a heel cleft to increase the flexibility of the sole. In a preferred embodiment, the strut members on the medial side are arranged at an angle to the strut members on the lateral side of the sole. The directional design provides flexibility and stiffness anisotropically to the sole in the longitudinal and lateral directions of the sole respectively.

The present invention relates to golf clubs having a movable weight which may be used to adjust the center of gravity of the golf club head. The golf club may include a slidable weight movable to various positions along a slot between the heel and the toe of the club. The head may include a cavity shaped to receive an insert. In one embodiment, a slidable weight consisting of a screw and a weight which may engage with each other may be configured to move along the length of the insert. During assembly, the weight may be inserted into an opening in the end of the insert and slid along a close fitting channel running the length of the insert. The weight's position along the channel may be secured by engaging the screw and tightening down the screw with a portion of the insert secured between the screw head and the weight. The assembled insert and slidable weight may then be press fit into the cavity in the head. By adjusting the position of the weight and screw within the insert, the center of gravity of the golf club may be adjusted.

A midsole structure for a shoe which improves a ride feeling and stability of the midfoot portion of the sole assembly during running. The sole assembly 1 of the shoe includes the upper plate 3 disposed on the upper side of the midfoot portion M and formed of a hard elastic member, the lower plate 4 disposed under the upper plate 3 to form the void S with the upper plate 3, formed of a hard elastic member, and having a downwardly convexedly curved shape, the midfoot outsole 6 attached on the bottom surface 4a of the lower plate 4, having the ground contact surface 6a, and provided discretely in the longitudinal direction from the outsole 5 of the heel portion H and the outsole 7 of the forefoot portion F of the sole assembly 1, and the connections 8, 9 provided on the front and rear ends of the midfoot portion M and interconnecting the upper plate 3 with the lower plate 4 in the vertical direction.
