An Afghan employee works at the Boot Factory in Kabul, September 8, 2012. Flip flops with AK 47 bullet primers may seem an unusual fashion choice for U.S. beach-goers, but one U.S. Special Forces veteran hopes the factory he's set up in Kabul to make the footwear will help bring a better life to people in Afghanistan.

People enjoy the beach in beachhouses as flipflops for sale are seen on Little Paradise beach on the outskirts of Azzeffoun town in Tizi Ouzou in this picture taken August 4, 2008. It looks like any Mediterranean resort: Young women in bikinis frolic in the surf and old folk doze under parasols in the baking heat. But visitors to the beach at Azeffoun sometimes get an audible clue to the kind of bloodshed that killed eight people on the Algerian coast on Saturday and prompts embassies to warn travellers to stay well away from Algeria's Kabylie region.

A woman walks with flip flops in Washington, July 15, 2003. Flip-flops in
the nation's capital typically mean politicians switching positions on an
important issue like abortion or taxes, but not this summer. Instead, the
flip-flop resonating in Washington and across the country is the snapping
sound coming from women's feet as they adopt thong sandals as the
comfortable shoes to wear to work, on a hot date or just to the grocery
store. Picture taken July 15, 2003. NO RIGHTS CLEARANCES OR PERMISSIONS ARE REQUIRED FOR THIS IMAGE REUTERS/William
