Designation:F53901(Reapproved 2011)An American National StandardStandard Practice forFitting Athletic Footwear1This standard is issued under the fixed designation F539;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers a practical method for fittingathletic footwear.This practice is applicable to the followinggeneral flexible types of footwear:running baseball,basketball,football,and tennis.1.2 There are as many variations in shoe forms and mate-rials available to users as there are variations in the anatomy ofthe users feet.Shoe forms are different due to manufacturersmaterials,type of construction,and also the type of activityanticipated in its end use.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Terminology2.1 Definitions:2.1.1 end use,nthe use for which the footwear is intended.2.1.2 last,na block or form shaped like a persons foot,used by shoemakers in building or repairing shoes and boots.2.1.3 improperly fitteda term descriptive of footwear thatis either too loose or too tight on the foot for its intendedpurpose or protection thereof.2.1.4 subjectperson on whom foot measurements aremade.3.Significance and Use3.1 Improperly fitted footwear can cause discomfort,butmore importantly,prolonged use causes disfiguration of thebone structure,bunions,corns,callouses,and finally fatigue,often leading to serious accidents.Footwear performance mayalso be diminished if improperly fitted.4.Apparatus4.1 Measuring Device,2suitable for performing the measure-ments described in this practice.5.Measurement Procedure5.1 Prepare the measuring device by setting the movablewidth bar to its widest position and with the movable ball toheel length indicator(pointer)slid back,so that the foot can beeasily positioned in the device(Fig.1).5.2 The subject should be in a standing position duringmeasurement of the foot with footwear removed from bothfeet.The subject should wear a sock similar to one that will beworn while wearing the footwear being fitted.5.3 Have the subject place their right heel in the areamarked for the right heel.The person being measured shouldstand with their weight distributed equally between both feet toensure that the foot has elongated to its maximum size.Toensure the heel is properly located in the back of the heel cup,grasp the ankle and device together(Fig.2).5.4 Determination of Toe-to-Heel Length(Toe Length)Take measurement by looking straight down over the end ofthe toes.Make sure the sock is pulled tightly over the toeswithout drawing the toes back.Press the toes down so that theylie flat against the base of the device and read the size of thelongest toe(not always the first toe).This is the toe-to-heelmeasurement(see Fig.3).5.5 Determination of Ball-to-Heel Length(Arch Length)Place the thumb over the ball joint of the foot as shown in Fig.4 and move the pointer so that the inner curved side of thepointer fits around the ball joint of the foot and the two highribs of the pointer come in contact with the thumb as shown inFig.4.When the pointer is in proper adjustment,the lowmiddle rib(marked A in Fig.4)will be touching the bone onthe side of the foot(marked B in Fig.4).This may be checkedwith the index finger.Read the size indicated by the pointer asthe arch length.1This practice is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing Surfaces,and Facilitiesand is the direct responsibility ofSubcommittee F08.54 on Athletic Footwear.Current edition approved Nov.1,2011.Published February 2012.Originallyapproved in 1978.Last previous edition approved in 2007 as F539 01(2007).DOI:10.1520/F0539-01R11.2The sole source of supply of the apparatus known to the committee at this timeis the Brannock Device Co.,509 East Fayette St.,Syracuse,NY 13202.If you areaware of alternative suppliers,please provide this information to ASTM Interna-tional Headquarters.Your comments will receive careful consideration at a meetingof the responsible technical committee,1which you may attend.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.6 Determination of Measured Foot Length in Terms ofShoe SizeCompare the arch length with the toe length and fitas follows:5.6.1 If the arch length and toe length measurements are thesame,the reading is the correct shoe size.5.6.2 If the arch length and toe length measurements differ,the shoe size should correspond to the larger of the twomeasurements.NOTE1If the arch length is significantly larger than the to
