(Practice)Standard Practice for Fitting Athletic Footwear
Standard Practice for Fitting Athletic Footwear
SIGNIFICANCE AND USE
Improperly fitted footwear can cause discomfort, but more importantly, prolonged use causes disfiguration of the bone structure, bunions, corns, callouses, and finally fatigue, often leading to serious accidents. Footwear performance may also be diminished if improperly fitted.
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: running baseball, basketball, football, 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 does not purport to address all of the safety concerns, if any, 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.
