Incrediwear - Trek Socks Green/Grey Large

Product Notes:

Incrediwear socks offer luxury and sophistication that is unavailable in other socks. Keeping you warm when it's cold out and cool when it's warm, Incredisocks perform -- living up to their high standards of excellence. They're a great choice not only for hikers and for work boots, but also for diabetics and others who have poor circulation in their feet. The Incrediwear Trek socks feature additional arch support, a breathable toe box, and strategically placed mesh for optimal cooling.

There are four types being offered here, each containing between about a quarter to three quarters of Incrediwear's signature bamboo charcoal fiber, which not only has therapeutic anions which stimulate blood and oxygen flow to warm the feet and reduce swelling, but also have natural antimicrobial properties to neutralize the bacteria which cause odors.

The initially listed Gray & Black ones feature a 78% blend of Bamboo and Germanium for that purpose, plus 22% Flexible Fibre.

The next two types (the black with green stripes, and the red with charcoal stripes), which have sometimes been labelled as Hiker/Worker socks, consist of 48% Cotton, 22% Bamboo Charcoal Fiber, and 30% Flexible Fiber, for tougher endurance. Wear and wash these Trek Tough Endurance Socks as often as you like, because they actually become softer and thicker with frequent washings. 

The final, all black ones being offered are a blend of 54% Cotton; 24% Bamboo Charcoal Fiber; 7% Nylon; 8% Rubber; and 8% Spandex.

Care instructions: Wash warm or cold. Tumble dry low. Do not bleach, iron or dry clean
