7番アイアン使用時は、肩と同じ幅で立つ
The feet should be set apart the width of the shoulders
when you are playing a standard five-iron shot.
They are set somewhat closer together when ypu play the more lofted clubs,
somewhat wider than the width of the shoulders when you play the long iron and the wood.
当然、ショートアイアンでは、それより狭いスタンスをとる。
右足は、飛球線に対して直角にする
there is one correct basic stance:
The right foot is at a right angle to the line of flight
and left foot is turned out a quarter of a turn to the left.
右足は、飛球線に対して直角にするが、右足は22.5°くらい左に開く。
