Test pieces are clamped into the testing machine and repeatedly flexed at a certain angle along the natural flexing line for a certain number of cycles. The degree of damage or crack is observed and evaluated visually.
The Flexing number and angle are adjustable depending on the type of shoes.
The footwear specimen is repeatedly flexed through a specified angle about its natural flexing line by a test machine. After a preset time or number of flexes the footwear is subjectively assessed for signs of damage. The number of flexes or the time betweeen assessments, and the angle through which the footwear is flexed, are all determined by the type of footwear being tested.
