Rule 5.1 of the Technical Rules should be interpreted widely in terms of what “could impede the view of the judges”, including athletes wearing their hair in a particular way.
Athletes may compete barefoot or with footwear on one or both feet.
One-off shoes made to order to suit the characteristics of an athlete's foot or other requirements are not permitted.
5.2.2 Where World Athletics has reason to believe that a type of shoe or specific technology may not comply with the letter or spirit of the Rules, it may refer the shoe or technology for detailed examination and it may prohibit the use of such shoes or technology in competition pending examination. Note (i): At least four months prior to an International Competition at which an athlete proposes to wear a shoe that has not previously been used in International Competitions, the athlete (or their representative) must submit to World Athletics the specification (i.e. size, dimensions, sole thickness, structure etc.) of that new shoe; confirm if the new shoe is to be customised in any way; and provide Amendments to Rule 5 of the Technical Rules (formerly Competition Rule 143) Approved by Council on 15 July 2020, effective from 28 July 2020 Amendments to Rule 5, in force on 28 July 2020 2 information about the availability of the new shoe on the open retail market (i.e. either in store or online). After reviewing this information World Athletics may request that samples of the shoe be submitted by the manufacturer for further examination. If the shoe is requested for further investigation, World Athletics will use reasonable efforts to complete its examination as soon as practicable (if possible, within 30 days of receipt of the shoe by World Athletics). Note (ii): Transition Period 31 January 2020 to 8 August 2021. This note has been inserted in recognition of the fact that on 15 July 2020 a Working Group on Athletic Shoes has been established by Council which by the end of the year 2020, in collaboration with manufacturers, will review the entirety of this Rule 5 as it applies to shoes by the end of the year 2020. The following notes (a) to (e) will assist in guiding all stakeholders with the practical application of this Rule 5 as it applies to all shoes (road or spike shoe) until and including, 8 August 2021.
