Born in 2002, Crocs is the originator of the "hole shoes", and even Bush is wearing them. Originally intended for rowing, Crocs shoes have taken the world by storm in 2003 due to their excellent slip resistance and comfort, and have also won the Ergonomics Society certification from Ergo in the United States to minimize the possibility of injury to the human body when worn. Although it was voted by many fashionistas as the ugliest shoe after the UGG boot, the company's stock price rose on the first day of a footwear company's IPO in 2006 when it went public on the NASDAQ. The one-piece Croslite™ material is non-slip and antibacterial, lightweight and stretchy, and it is also as comfortable and practical as the flip-flops launched by companies such as Disney, which range in price from more than 100 to 5600. When Crocs' sales declined, some people said that it was caused by the wear-resistant material and the fact that it was rarely replaced. Parents should note that many children prefer to wear double-worn shoes, but due to the soft material, there have been many accidents around the world where children have been pinched by escalators.
