I came across this awesome magazine advert advert from the 1980s for Chuck Norris Action Jeans.
Apparently they are:
“Developed for stunt fighting in action movies.
These look and wear like regular western jeans but have hidden-gusset and stretch in the fabric so they won’t bind your legs or rip out.
Redesigned to give a better fit in the waist and thighs.
Action Jeans are boot-cut style and are left unhemmed to be tailored to your exact length.”
And those shoes really makes the picture.
