b) The requirements and test method for appearance quality are added (see

c) The requirements and test method for the flexural property of the whole shoe are modified (see Table 1 in 5.3, and 6.3.1; Table 2 in 5.3, and

6.9 of Version 2008), and "cold resistance of finished shoes" is modified into "low-temperature flexural property" (see Table 1 in 5.3, and 6.3.2; Table 2 in 5.3, and

6.17 of Version 2008);

1 Scope

GB/T 21536-2024 is the Chinese product standard for track and field shoes: spikes and racing flats. It is a small standard for a category that has become technically contentious, since the carbon plate and thick midsole shoes that transformed distance running raised the question of where a shoe stops being footwear and starts being equipment. The standard sets the classification of the shoes by event, the requirements on the materials and construction, the dimensional and fitting requirements, the physical requirements including the peel strength of the sole bond, the abrasion resistance and flex resistance of the outsole, the attachment strength of the spikes and the spike plate, the slip resistance, the mass, the colour fastness and the requirements on the harmful substances in the materials, together with the test methods, the inspection rules and the marking, packaging, transport and storage. The 2024 edition replaces GB/T 21536-2008. For a shoe maker, a brand sourcing in China or a buyer inspecting a delivery, this is the acceptance text.

This document provides the classification of track and field sport shoes, specifies the technical requirements and inspection rules, marking, packaging, transportation and storage, and describes the corresponding test methods. This document applies to spikes and non-spike shoes worn in track and field sports (including running, jumping, throwing and walking, etc.).
