National Flip Flop Day
May 28, Wednesday
History and Origin
* Flip flops — sandals with a strap between the toes — have existed for thousands of years, with prototypes in Ancient Egypt, Greece, Rome, and Japan (the Japanese “zōri”).
* The modern fondness for this footwear emerged after World War II, when American soldiers brought flip flops from Japan.
* The day was officially established in 2007 by the Tropical Smoothie Cafe chain — as a celebration of the brand’s 10th anniversary and a way to support the charity organization Camp Sunshine.
How the Day is Celebrated
* Wear your favorite flip flops — to work, the store, the beach, or just at home.
* Visit Tropical Smoothie Cafe on the holiday: typically, from 2 to 7 PM, guests wearing flip flops receive a free 12 oz “Sunrise Sunset” smoothie.
* Many people organize at-home or public “flip flop day” events — wearing them all day and sharing photos on social media with the hashtag #NationalFlipFlopDay.
* Some cafes enhance the celebration with flip flop decoration workshops, beach-themed events, and games.
Charitable Aspect
* Through the Tropical Smoothie Cafe campaign, millions of dollars have been raised for Camp Sunshine — a support center for children with serious illnesses and their families.
* This way, the holiday combines a light summer atmosphere with an opportunity to help those in need.
Why It Matters
* It reminds us of the importance of simple joys and relaxation, especially after a long winter.
* It promotes comfortable yet stylish footwear suitable for any occasion — from the beach to casual hangouts.
* It shows that even small actions, like wearing flip flops or drinking a smoothie, can be connected to charity and helping others.
