True story: It first happened to me 35 years ago (guessing) while working in the golf shop.
FootJoy debuted a lightweight golf shoe and we had them on display.
Not ten minutes after resting the pair of shoes on top of the box, a member comes in, picks up the display shoe and literally tosses it up in the air several inches and catches it on its way down. After 5 or 6 tosses, he blurts out...
THIS is what I need! My golf shoes are so heavy!
I immediately thought... yeah, you should get a pair. I am tired of getting calls in the shop to head out to the 15th hole and pick up Mr. Wetterston because he can't take another step in his old, heavy shoes.
