Flip Side Flip Flops

These disposal habits may pose an environmental problem because most flip-flops are made with polyurethane, which comes from crude oil. This material is a number seven resin and cannot usually be recycled in small amounts. Because of growing environmental concerns, some companies have begun to sell flip-flops made from recycled inner tubes or car tires, as well as sustainable materials like hemp, cotton and coconut.
Flip-flops are also popular with those who enjoy being barefoot but need to wear shoes, since they allow the foot to be out in the open but still constitute a shoe for wear in places such as restaurants or on city streets, and can be quickly and easily removed. They are also popular because they are easy to carry and come in an assortment of colors and patterns.
On July 19, 2005, some members of Northwestern University's national champion women's lacrosse team were criticized for wearing "flip-flops" to the White House to meet with President George W. Bush. The women pointed out that their shoes were not "beach shoes," but were dressier thong sandals.
