Thermal comfort plays a crucial role in the performance and well-being of mountaineers, especially in extreme environments. The aim of this study was to develop a reliable protocol to assess the thermal comfort of mountaineering boots, with a specific focus on temperature variations in different regions of the foot and their correlation with physiological factors. Two different models of mountaineering boots were tested at two different environmental temperature (-15°C and -30°C). The mean skin temperature, measured according to International Standards BS EN ISO 9886:2004, was used as an indicator of overall thermal comfort. Physiological factors such as heart rate (HR), body mass index (BMI) and body surface area (BSA) were also measured to understand their relationship to thermoregulation. Kruskal-Wallis and Pearson's ProductMoment correlation tests were performed to investigate whether there was a statistically significant relationship.

The results showed significant differences in foot temperature among the Testers, indicating variations in the perception of thermal comfort. The correlation analysis showed a strong positive relationship between mean skin temperature and HR, highlighting the influence of physiological factors on thermal comfort.

In addition, the analysis showed that the dorsum and hallux areas had the largest temperature variations, suggesting the occurrence of vasoconstriction and potential discomfort.

This study represents a preliminary approach to establishing a reliable protocol for assessing the thermal performance of cold protective footwear.

热舒适度对于登山者的表现和健康起着至关重要的作用，尤其是在极端环境下。本研究的目的是开发一种可靠的方案来评估登山靴的热舒适性，特别关注脚部不同区域的温度变化及其与生理因素的相关性。两种不同型号的登山靴在两种不同的环境温度（-15℃和-30℃）下进行了测试。根据国际标准 BS EN ISO 9886:2004 测量的平均皮肤温度被用作整体热舒适度的指标。还测量了心率 (HR)、体重指数 (BMI) 和体表面积 (BSA) 等生理因素，以了解它们与体温调节的关系。进行了 Kruskal-Wallis 和 Pearson 的 ProductMoment 相关性测试，以调查是否存在统计上显着的关系。

结果显示，测试者的足部温度存在显着差异，表明热舒适感的感知存在差异。相关分析显示平均皮肤温度与心率之间存在很强的正相关关系，凸显了生理因素对热舒适性的影响。

此外，分析显示，手背和拇趾区域的温度变化最大，提示发生血管收缩和潜在的不适。

这项研究代表了建立评估防寒鞋热性能的可靠协议的初步方法。
