A golf club head is formed having weighting material of a density greater than the density of the parent head material positioned at the sides of the club head to increase the inertia effect of the head. The weighting material can be arranged to increase the inertia effect of the head and at the same time shaped to locate the centre of gravity of the head in alignment with the shaft centre line. The invention also contemplates the pre-positioning of the weighting material at a specified distance from the bottom of the club head whereby the swingweight may be changed without either changing the overall weight of the club or the head and/or changing the shaft flex. The invention also provides a design of soleplate to increase the inertia effect when attached to a golf club head.
