- 04Air temperature within polymer footwear rose from 29.0°C to 34.7°C, decreasing to 33.7°C after rest.
- 05Relative humidity reached 91% in leather footwear and 96.6% in polymer footwear.
Application
Design takeaway
Designers of protective footwear must prioritize thermal and moisture management to enhance user comfort and safety, especially for prolonged or strenuous use.
How to apply
When designing or evaluating protective footwear, measure and analyze the internal temperature and humidity dynamics under simulated use conditions.
Project actions
- 01Consider how different materials affect the internal environment of a product.
- 02Think about how user activity influences the product's performance and user experience.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Continuous monitoring of microclimate parameters.
- +Inclusion of both activity and rest periods to observe recovery dynamics.
Limitations
Laboratory conditions might not reflect real-world use. The specific activities and duration might differ from actual scenarios.
Reliability & validity
Reliability could be enhanced by repeating the experiment with the same participants and conditions. Validity is supported by the direct measurement of key microclimate parameters.
Think critically
How might the findings on microclimate in firefighter boots apply to the design of other types of enclosed footwear, such as athletic shoes or work boots?
Design Principles
"Optimize the internal microclimate of enclosed personal protective equipment to maintain user comfort and performance."
Understanding the internal environmental conditions of protective gear is crucial for ensuring user comfort, performance, and health. High temperatures and humidity within footwear can lead to discomfort, reduced dexterity, and an increased risk of skin issues or heat-related stress for individuals in demanding occupations.
What This Means for Your Design
Wearing firefighter boots makes your feet hot and sweaty because the boots trap heat and moisture inside.
