Abstract: The quality of the current cold-resistant leather shoes in terms of low temperature flexure resistance was analyzed according to the standard QB/T 4547-2021 "Technical specification for cold-proof performance of leather shoes". According to the principle of biomimetic mechanics, the standard simulated the actual situation of human walking in cold weather, and made a more comprehensive investigation on the low temperature flexure performance of leather shoes. Representative samples of cold-resistant leather shoes were selected to test their whole-shoe low-temperature flexibility, and the low-temperature flexibility was analyzed from the aspects of use object, upper materials, sole materials, and so on.
