Wooden soled shoes have good anti-slip performance and are very comfortable to wear. After making some modifications on the original basis, they designed a kind of shoes originally prepared for boating. This kind of shoes is very similar in shape to slippers. The vamp is covered with holes, and there is also a rotatable belt to prevent slipping. In 2002, crocodiles received great attention at the Fort Lauderdale International Expo. In 2004, CROCS acquired a patented Canadian company and named this material Crostile Plastic. This material is plastic with closed bubbles, which can automatically deform to adapt to the shape of feet under the action of body temperature. The company and its main product name is CROCS, which means the nickname of crocodile. Because crocodile is a strong reptile without natural enemies, this is very close to the company's product positioning. However, the company also had a dispute with the French crocodile company, which is also a clothing industry.
