Show allegiance to your country by wearing your flag on your feet (Is it legal?). Here are some of the shoes I have found that are patriotic.
Canadian flag design by DSQUARED2 available at Yoox which is also available in flats.
Hail to the Queen! These flats by Alexander McQueen is available at Zappos.
These are ugly. Don't you dare.
Better than the previous one but still not wearable in public.
Although this a Giuseppe Zanotti design, it still doesn't quite fit the description of a wearable shoe in public. You can try it here.
And if you still couldn't get enough of these shoes, you can have your own customized... you can even put the flags of the members of United Nations on your shoe, visit here for details.
