Trail running socks with varying wave separations showed similar thermoregulatory effects on foot sole temperature during a mountain race. Perceived thermal comfort did not align with objective temperature measurements, suggesting interchangeability for short races.
Area of Science:
- Sports Science
- Textile Engineering
- Human Physiology
Background:
- Trail running socks vary in thermoregulatory properties based on design.
- Three-dimensional wave separations in socks may influence foot temperature.
- Understanding these effects is crucial for athletic performance and comfort.
Purpose of the Study:
- To compare the thermoregulatory effects of two trail running sock models with different wave separations.
- To evaluate foot sole temperatures after a mountain race using thermal imaging.
- To assess runners' perceived thermal comfort with each sock model.
Main Methods:
- 34 runners (27 male, 7 female) participated in a 14 km mountain race at 27°C.
- Plantar temperature was measured using a thermal imaging camera (Flir E60bx®) before and after the race.
- Two sock models with 2 mm (AWC 2.2) and 1 mm (AWC 3) wave separations were tested.
- A Likert-type survey assessed perceived physiological characteristics and thermal comfort.
Main Results:
- Both sock models significantly increased foot sole temperature post-race (p < 0.001).
- The hallux area showed the greatest temperature increase.
- No significant differences in temperature changes were observed between the two sock models.
- Runners reported significantly greater thermal comfort with AWC 2.2 socks (4.41 ± 0.62) compared to AWC 3 (3.76 ± 1.03) (p = 0.034).
Conclusions:
- Both trail running sock models exhibit similar thermoregulatory effects on the foot sole.
- The models can be used interchangeably for short-distance mountain races.
- Perceived thermal comfort does not directly correlate with measured temperature data.
