This study investigates foot sweat distribution with and without shoes and the relationship between foot sweat distribution and perceived wetness to enhance guidance for footwear design. Fourteen females performed low-intensity running with nude feet and low- and high-intensity running with shoes (55%VO and 75%VO, respectively) on separate occasions. Right foot sweat rates were measured at 14 regions using absorbent material applied during the last 5 min of each work intensity. Perceptual responses were recorded for the body, foot and four foot regions. Foot sweat production was 22% greater nude ( < .001) and with shoes did not increase with exercise intensity ( = .14). Highest sweat rates were observed at the medial ankle and dorsal regions; lowest sweat rates at the toes. Perceptions of wetness and foot discomfort did not correspond with regions of high sweat production or low skin temperature but rather seemed dominated by tactile interactions caused by foot movement within the shoe. This study provides a detailed view of foot sweat distribution for female runners with and without shoes, providing important guidance for sock and footwear design. Importantly, perceptions of wetness and foot discomfort did not correspond with areas of high sweat production. Instead tactile interactions between the foot, sock/shoe play an important role. VO: maximal oxygen consumption; HR: heart rate; RH: relative humidity; GSL: gross sweat loss; Nude-I1: without socks and shoes, low intensity running; Shod-I1: with socks and shoes, low intensity running; Shod-I2: with socks and shoes, high intensity running.
本研究调查了有鞋和无鞋时的足部汗液分布情况，以及足部汗液分布与感知潮湿之间的关系，以增强对鞋类设计的指导。14 名女性分别穿着裸体、低强度（55%VO）和高强度（75%VO）的鞋子进行低强度跑步，在每个工作强度的最后 5 分钟使用吸水性材料测量右脚 14 个部位的汗液率。记录身体、脚部和四个脚部区域的感知反应。裸体时足部汗液产生增加 22%（<0.001），而运动强度增加时鞋子不会增加（=0.14）。最高的汗液率出现在内踝和脚背区域；最低的汗液率出现在脚趾处。潮湿和脚部不适的感觉与高汗液产生区域或低皮肤温度不对应，而是似乎主要由鞋内脚部运动引起的触觉相互作用所主导。本研究为有鞋和无鞋的女性跑步者提供了详细的足部汗液分布视图，为袜子和鞋类设计提供了重要指导。重要的是，潮湿和脚部不适的感觉与高汗液产生区域不对应。相反，脚、袜子/鞋子之间的触觉相互作用起着重要作用。VO：最大摄氧量；HR：心率；RH：相对湿度；GSL：总汗损失；Nude-I1：无袜子和鞋子，低强度跑步；Shod-I1：有袜子和鞋子，低强度跑步；Shod-I2：有袜子和鞋子，高强度跑步。
