I had asked Sealskinz these questions:
Your “technology” page says that the socks work because “the external climate is much drier and cooler”. Does this imply that your socks are less effective, or useless, in a warm climate?
You also state that sealskinz socks reduce blisters. How? By just keeping the foot dry or in some other way?
What about the smell? How do your socks and gloves behave from this point of view, when used in long (many days) winter and/or humid areas treks?
This is Sealskinz’s answer:
SealSkinz socks will reduce the chance of blistering as they stop your feet from getting wet and wick away the perspiration, preventing your skin from becoming soft and far more vulnerable to sore feet and blisters. The membrane is breathable and the inner liner will ‘wick,’ away the moisture, to help with the clammy feeling. And it will also avoid smelling. Sealskinz Socks work in warm and cold climate.
