Resistance of footwear to flexing

November 2016

SCOPE

This method is intended to assess the resistance of completed footwear to repeated flexing. The method is applicable to most types of footwear. It is not suitable for assessing the flex crack resistance of upper or soling materials.

PRINCIPLE

The footwear specimen is repeatedly flexed through a specified angle about its natural flexing line by a test machine. After a predetermined time or number of flexes the footwear is subjectively assessed for signs of damage. The number of flexes or the time between assessments, and the angle through which the footwear is flexed, are determined by the type of footwear being tested.
