About RANDY SUN waterproof socks, what you need to know before you buy?

How do waterproof socks work?

Waterproof socks keep feet dry by preventing water from seeping through the fabric. They achieve this purpose by utilizing a waterproof and breathable membrane as middle layer of the socks.

This does not mean that the out shell of the socks will repel water or be dry, but you should expect that your feet stay warm and dry underneath these socks. 

Do the feet sweat with the socks ?

The two elements of the waterproof breathable membrane work together to keep the feet dry, with the waterproofing keeping water out and the breathable properties ensuring that the moisture created as you sweat is allowed to escape out of the sock. I’ve hiked in these socks for 13 miles through mud and rivers without any issues.

Are they comfortable?

Yes! Their decent thickness provides shock absorption and long-lasting comfort. Soft materials prevent blisters and uncomfortable chafing.

Which style should I choose?

Different activities will require different thickness and sock length, but our mid-calf socks in regular thickness is always the most popular style for most activities and almost all weather.

Recommended waterproof socks for for different climates:

  • Warm Weather - Thin, Ultra Thin. Its thickness is almost the same as your cotton socks.
  • All Weather- Regular Thickness. Usually all waterproof socks will be bulkier than your normal socks. You may need to wear them with loose shoes.
  • Cold Weather- Thick. Ideal to wear when it's close to 0 degree Celsius (32 degree Fahrenheit), or when you need to walk in a cool stream in the mountains in cold weather.
  • Extreme Cold Weather - Very Thick. They are normally suitable for use in temperatures between 0 degree Celsius and -10 degrees Celsius (14 to 32 degree Fahrenheit). In extreme temperatures colder than -10 degrees Celsius, the waterproof socks will still keep your feet warm, but the waterproof membrane in the middle layer will become brittle and lose its waterproof properties.

If you need customized waterproof socks that are effective in extreme cold, such as -40 degrees Celsius (-40 degree Fahrenheit), please contact us via Please be aware that developing these socks requires a completely different specialty waterproof membrane, so there will be a higher MOQ.

Tips: When your feet are submerged in water, although your feet are dry, you may still feel the coolness of the cold water through your socks, especially when you are active in the mountains, at this time you can choose thicker waterproof socks, or, to be flexible you can add a pair of your usual thin socks underneath the waterproof socks to easily cope with the changing weather.
