“…Foot is usually higher than ambient and footwear surface temperature resulting in heat transfer through convective and radiative pathways. It would be expected that during running, convective heat transfer would be high due to increased air flow around the shoe in addition to movement of the foot within the shoe causing a pumping action forcing air into the environment (Havenith et al 1990;Satsumoto et al 2016).…”

“…Although there were no significant differences in sock sweat absorption between shoe conditions, in-shoe relative humidity and in-shoe absolute humidity values were greater for the closed shoe. It is suggested that increased ventilation can be effective in limiting an increase in skin moisture concentration (Ueda et al 2006;Satsumoto et al 2016). As a result, the mesh upper construction of the open shoe resulted in greater ventilation and therefore a reduction in the amount of moisture accumulated within the shoe.…”

Shoe microclimate: An objective characterisation and subjective evaluation

Shoe microclimate (temperature and humidity) has been suggested to contribute to perceptions of foot thermal comfort. However, limited data is available for perceptual responses in relation to shoe microclimate development both over time and within different areas of the shoe. This study evaluates perceptions of foot thermal comfort for two running shoes different in terms of air permeability in relation to temporal and spatial characteristics of shoe microclimate. The temporal characteristics of shoe microclimate development were similar for both shoes assessed. However, higher temperatures and humidity were observed for the less permeable shoe. Changes to shoe microclimate over time and differences between shoes were perceivable by the users.This study provides the most detailed assessment of shoe microclimate in relation to foot thermal comfort to date, providing relevant information for footwear design and evaluation. physical activity where the feet are enclosed in shoes for extended periods of times i.e. marathon runners (Auger et al. 1993). Intermediate levels of moisture have also been shown to increase coefficients of friction which have been found to influence the probability of blister formation (Sulzberger et al. 1966). Changes to the shoe microclimate therefore encourage the growth of microorganisms which can lead to odour development and to poor foot health. Knowledge regarding the subjective evaluation of shoe microclimate is limited, with little published information available. Although subjective perception of foot may not always coincide with measured foot (Barkley et al. 2011), local discomfort has been attributed to elevations in temperature rather than elevations in the moisture content both within hiking boots (Arezes et al. 2013) and within sock and boot liner materials worn within protective footwear (Irzmanska et al. 2013). The influence moisture has on foot comfort therefore requires further investigation as it is unknown whether changes in temperature and/or humidity help an individual in determining perceptions of thermal comfort. Despite the impact shoe microclimate has on foot health and foot thermal comfort, to our knowledge no quantitative shoe microclimate data is available over time, within different areas of the shoe or in relation to perceptual responses specifically for sports related footwear. With exercise, metabolic heat generation and sweat rates are high and so balancing the amount of heat supplied to or generated by the feet with heat loss becomes crucial. Currently, only changes to foot during running have been reported (Barkley et al. 2011; Shimazaki and Murata 2015; Shimazaki et al. 2015). During a 30 minute running bout at 12 km hr -1 temperature elevations from rest of 8.2°C were observed at the heel and 4.8°C at the neck of the big toe, foot regions associated with high contact loads and pressure during running (Shimazaki and Murata 2015). Increased ventilation within running shoes has also been shown to produce a cooling effect, reducing foot elevations, particula...

“…High convective heat transfer would be expected due to foot movement within the shoe and airflow around the footwear. 23 There was no forced convection around the foot during standing in the current study, and the thermal resistance of the footwear played an important role in in-shoe temperature increase. The training shoes, with a greater thermal resistance, showed higher in-shoe temperature elevations than firefighting boots during standing.…”

Maintaining foot comfort is important as it influences the overall comfort of the human body. Shoe microclimate and foot skin temperature have been suggested to contribute to the thermal sensation of the foot. Considering the thermal environment and personal protective equipment (PPE) used for structural and proximity firefighting, climatic chamber tests with 13 male participants were conducted during standing and walking. Four test conditions – unloaded with training shoes, loaded with training shoes, unloaded with firefighting boots, and loaded with firefighting boots – were designed to investigate the effects of firefighting boots and PPE load on the thermal comfort of the human foot. Physiological variables of in-shoe and foot skin temperature at the whole and local regions of the foot were measured and subjective responses were gathered using psychological scales. The results showed that wearing firefighting boots may elevate the thermal sensation of wearers. The PPE load increased the in-shoe and foot skin temperature as well as subjective ratings. Subjective sensations of the foot were strongly correlated with in-shoe and skin temperature in the plantar regions. Correlation analysis of thermal sensation at the whole and local foot regions indicated that the sensation at the forefoot was closest to the whole foot, followed by the midfoot and heel. The findings address the relationship of physiological and subjective variables as well as the thermal sensation of whole and local foot regions, which can be considered for footwear design and thermal comfort prediction of the foot and whole body.
