When choosing socks, the material of the sock will determine a lot about the well-being of your feet. Even high-quality shoes can perform poorly with the wrong kind of sock. Does the sock insulate you from the cold? Does it breathe? Does it prevent sweating? Can it withstand wear and washing? We compared merino wool, cotton, bamboo and synthetic fibresso that you know exactly which material is suitable for which situation.

Socks work best when they are selected according to the prevailing conditions and the footwear in use.
Merino wool socks are versatile all year round thanks to the inherent technical properties of merino wool. They are a particularly good choice for everyday wear and outdoor activities. Choose the thickness of your merino wool socks according to the conditions and your footwear.
Cotton socks are the wash-and-wear choice for everyday wear. The durable material and easy care, with the option to wash at higher temperatures (60 degrees), are a great choice for the active indoor runner.
Bamboo socks caress your feet with their super soft feel. However, bamboo is not the best choice for situations where socks are subject to heavy wear (i.e. technical bamboo socks). For home and sleep socks, bamboo is wonderful for the summer season - in winter, bamboo can be cold.
Technical socks (made of synthetic fibres) are durable and long-lasting! Technical socks are designed to withstand super wear and tear. Generally, these socks should be selected for high wear indoor sports; group sports, racquetball, ball games, etc. Technical socks are also suitable for running in warm conditions. For running in cold weather, technical merino wool socks should be chosen to prevent the cold from biting your toes.
