Summary
Acrylic socks significantly reduce blister frequency and size in long-distance runners compared to cotton socks. This study highlights the importance of athletic sock material for preventing foot injuries during endurance activities.
Area of Science:
- Sports Medicine
- Textile Science
- Dermatology
Background:
- Blistering is a common and painful issue for long-distance runners.
- Sock fiber composition is a potential factor influencing blister development.
Purpose of the Study:
- To investigate the impact of acrylic versus cotton sock fibers on blister occurrence and severity in runners.
Main Methods:
- A longitudinal, double-blind study involving 35 long-distance runners.
- Comparison of 100% acrylic socks against 100% cotton socks, identical in all other construction aspects.
Main Results:
- Acrylic fiber socks demonstrated a lower frequency of blistering events.
- Blisters that did occur with acrylic socks were significantly smaller in surface area (mm2) compared to those from cotton socks.
Conclusions:
- Acrylic fiber socks offer superior performance in mitigating blister formation and severity for long-distance runners.
- Material choice in athletic socks is a critical factor for preventing running-related foot injuries.
