Ply on ply of fabric and rubber are 
built into the walls of the “U. S.” 
Boot . Here at the instep where 
heavy strains come are 8 
separate layers. 
A strip of rubber cut from a “U. S.” 
Boot stretches more than 5 times its 
length without breaking—and snaps 
back into shape like an elastic band. 
This live, elastic rubber is one of the 
reasons for the unusual flexibility 
and long wear of “U . S.” Boots. 
Where they bend and strain 
a thousand times a day . . 
Strength alone can’t insure boot wear 
Kneeling down—standing up again—tramping 
through slush and mire—you are putting your 
boots through a whole series of tests every day. 
They may be strong enough to resist the hard 
knocks, but are they able to stand up under the 
strain of continual bending? 
The new “U. S. ” Boot gives longer wear be¬ 
cause it has not only rugged strength, but also 
the flexibility to withstand every kind of strain. 
Strength, because of its reinforcements at 
every vital point. From seven to eleven separate 
layers of fabric and rubber are built into the 
“U. S. ” Boot at the four places where the strains 
are heaviest—ankle, back of the heel, instep, and 
sole. Real protection where it’s most needed. 
Flexibility, because of the rubber that’s used 
—rubber as live as an elastic band. Cut a strip 
of rubber from a “U. S. ” Boot and you’d find it 
would stretch more than five times its length 
without breaking! It’s this rubber that enables 
the “U. S.”T3oot to bend a thousand times each 
day without cracking or weakening. 
That’s why “U. S.” Boots last longer. And 
why so many farmers all over the country are 
wearing them today. 
Other “U. S.” Rubber Footwear 
You’ll find every type of rubber footwear in the 
big “U. S.” line. There’s the “U. S.” Walrus, 
the famous all-rubber overshoe—the “U. S.” 
lace Bootee, a rubber workshoe for spring and 
fall—“ U. S. ” Arctics and Rubbers—all styles and 
sizes for the whole family. Look for the “U. S.” 
trade mark whenever you buy—the honor mark 
of the largest rubber organization in the world.
