Standard Practice for Fitting Athletic Footwear
SCOPE
1.1 This practice covers a practical method for fitting athletic footwear. This practice is applicable to the following general flexible types of footwear: baseball, basketball, football, jogging, and tennis.
1.2 There are as many variations in shoe forms and materials available to users as there are variations in the anatomy of the user's feet. Shoe forms are different due to manufacturer's materials, type of construction, and also the type of activity anticipated in its end use.
1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
