My 4th of July shoe was Steve Madden's 'Lejune', which of course I found on sale just after New Years. It's still available at Zappos:
Steve Madden Lejune - Free Shipping Both Ways & 365-Day Return Policy
I also ran into these yesterday while I was trying to find some elusive pumps for another forum member, and they also shouted out '4th of July' to me (Various budgets):
Eley Kishimoto SH 187P4 (Orange/Purple/White) - Dress Shoes
Nau‏ghty Monkey Bud & Bloom (White) - Nau‏ghty Monkey Shoes
Christian Lacroix 973539 (Navy Fabric Cravate) - Christian Lacroix Women's Shoes
Not Rated Sissy Strut (Blue) - Not Rated Shoes

OK, so I love the idea of patriotic stars & stripes footwear.
