	This machine is used to test the zigzag characteristics of the middle bottom fiberboard, such as leather shoes, leisure shoes and jogging shoes. The test method is to turn the specimen to the left and right continuously for 90 degrees under a specific load. Until the specimen is destroyed, the tortuosity index of the middle floor is taken as the reference for comparison and selection of the middle floor.
