Hook is one of the main stress parts of high-heeled sandals, which is located inside the shoes. Whether the shoes are stable on the feet depends entirely on the function of hooking the heart under certain conditions. If the hook is too short or too soft, it can't play an effective supporting role, and the shoes may be skewed when walking, which may easily lead to personal injuries such as twisting feet and falling injuries.
This comparative test * * * has four pairs of high-heeled sandals, which is one of the projects with the largest number of samples.
The reporter saw in the laboratory that the hook of this high-heeled sandal was directly broken by the testing instrument during the bending performance test. The steel hook length of this pair of honey girl Tianxin brand high-heeled sandals produced by Shenzhen Xitian Clothing Co., Ltd. should be at least 1 15 mm, but the measured hook length is only 1 12 mm, which is 3 mm shorter than the standard requirement.
In addition to the lack of length, engineers also found that the hook hardness of this nominal SCHUTZ sandal is not enough, and the measured hardness is only half of the standard requirement.
