Cold feet
In winter, especially in cold climates the thermal-insulation quality of the sock is critical. New synthetic fibres composed of a hollow core material known as Thermax® have been shown to effectively insulate against heat loss. Natural wool fiber socks are still unbeatable for maintaining heat while wet. However, the abrasive nature of 100% wool fiber socks makes these more comfortable if blended with other high-tech synthetic fibre materials.
Choice of fibres
The classical cotton socks retain foot sweat, which soften the skin, leaving it more prone to breaking with friction, and blisters form. Synthetic socks made of acrylic, polypropylene, or CoolMax fabric wick moisture away from the foot, keeping them dry. These are available at most sports stores.
The following choices of fibres exist on the market:
Acrylic: Not usually recommended for running
Acrylic/Wool: Outdoor-Cold
Acrylic/Thermax®: Outdoor-Cool
Acrylic/CoolMax®: Outdoor-Warm
CoolMax®: Running
The trend towards compression socks
Your muscles work on oxygen which is transported via the blood pumped from your heart through arteries and viens. During intensive sport your heart rate rises to feed the muscles. This causes the calves to absorb blood very rapidly and because the calf muscles are situated at some distance from the heart and lungs, this can cause difficulty for the blood to evacuate effectively and result in an inadequate oxygenation of the muscles resulting in heaviness, fatigue and cramps and a reduction in performance. Women are especially prone to venous problems and might find these socks the answer.
Compression sports socks exert a slight pressure around the foot and ankle and calf which limits the dilation of the calf muscle and helps oxygenation, reducing risk of injury (tendonitis, muscle tears etc.). During training these socks can help improve performance and wearing them after effort can aid and accelerate recuperation.
Tips:
Do not sleep with socks on,
Use during long transportation trips, car, aeroplane etc.
Make sure that the socks are tailored to your specific measurement for maximum efficacy.
