Birkenstock puts a new twist on flip-flop design with the uniquely styled and incredibly comfortable Women's Gizeh Sandals. Their suede footbeds provide a soft feel you will rarely find in any footwear, while the EVA outsoles absorb shocks and reduce foot fatigue. If you want some flip-flops that actually support your feet and won't have to be replaced in a month, grab the Gizeh Sandals.
