hardest  tests  you  can  give  them — it 
takes  years  of  experience  to  make  a 
boot  like  that! 
THERE  are  four  places  in  a  boot 
where  the  strain  is  worst — ankle, 
back  of  the  heel,  instep,  sole.  And  a 
weakness  of  construction  at  any  one  of 
them  will  rob  you  of  wear  you  ought 
to  get. 
A  break  at  one  of  these  vital  points 
and  the  boot  is  no  longer  waterproof. 
“U.S.”  Boots  are  built  to  avoid  just 
this  sort  of  thing.  At  every  point  where 
these  strains  occur,  from  seven  to 
eleven  extra  re-inforcing  layers  of  fabric 
and  tough  rubber  are  built  into  every 
pair! 
No  wonder  they  stand  up! 
The  diagrams  at  the  left  will  show 
you  just  how  U.  S.  Boots  are  built. 
Notice  the  strong  reinforcements  built 
into  the  very  wall  of  the  boot. 
The  construction  of  U.  S.  Boots  is 
the  result  of  75  years  of  experience  in 
boot  making.  Light  enough  for  solid 
comfort — yet  strong  enough  lor  the 
back  of  the  heel — Eleven  layers 
nf  heavy  duck  and  highest  grade  rub¬ 
ber  make  this  one  of  the  strongest 
points  of  the  whole  boot.

the  ankle— Here's  where  so  many 
boots  sag  and  crack.  The  “U.  S.” 
Boot  has  an  extra  " collar ”  'hat  runs 
all  the  way  round  the  leg,  and  on  top 
of that  is  vulcanized  a  heavy  side-stay.
