A golf club shaft wherein the flexibility of the club over a short segment at the butt or grip end is increased in a controlled manner. A flexible tubular shaft insert of approximately 7 to 10 inches in total length having a tapered portion of approximately 2 to 3 inches in length and of increased diameter, the outer diameter of the tapered portion being sized and configured so as to mate with the inner diameter of the actual golf club shaft, is inserted into the shaft. A flexible sleeve is disposed about the exposed extension portion of the tubular shaft insert, the outer diameter of the flexible sleeve approximating the outer diameter of the golf club shaft, such that a standard grip may be applied over the butt end of the shaft and the extended portion of the shaft insert.
