Iced Tea Is an English
Richard Blechyden, an Englishman, had a tea concession

Don't Wear Cotton Socks
Once cotton gets wet, it stays wet, bunches up, and can
lead to blisters. (Cotton also becomes abrasive and
loses its shape when it's washed.)
On the other hand, socks made from synthetic fibers
will keep their shape, wick water away from your skin,
stay dryer, and keep your feet cooler.
The new fiber trade name CoolMax works best.
Teflon is now being used in BlisterGuard socks by
SmootheEase. Acrylic fibers (much cheaper) work
well, especially when blended with other fibers. Source:
