Lamb's wool, or virgin wool, is the actual first shearing of the lamb that produces a fiber with a unique combination of softness and resiliency. Combined with stretch nylon and polyester, these natural qualities are enhanced to provide better wicking characteristics, more durability and ultimately, more comfort.

• Exclusive Extra Fine Merino Blend for BETTER WICKING and INSULATION
• Thin cushioning in ball/heel for MORE BLISTER PROTECTION than any other thin sock product on the market today
• Stretch nylon with a flat knit arch IMPROVES FIT

Fiber Contents: 48% extra fine Merino wool, 37% nylon, 13% polyester, 2% elastic

• This loss of fat pads is due primarily to damage from shearing forces from walking and running on smooth, unyielding man-made surfaces (concrete, asphalt, hard floors).
• The damage is compounded by poorly designed and poorly fitted socks and shoes.
• Thorlos protect the fat pads from shearing forces by transferring these forces from the fat pads to the cushion fabric of the Thorlos; and where fat pad degradation has already occurred, Thorlos engineered cushion fabric helps replace the function of the natural pads.

• Cotton, wool and silk (all natural fabrics) absorb moisture ["Absorption" is defined as retention]. Wool claims to "wick," which is not true.
• Inside the shoes, natural cushion sock fabrics become ineffective and even harmful to the feet: They absorb moisture, become saturated and collapse. Result: no protection.
• Acrylic "wicks" moisture ["Wicking" is defined as transmission or movement of moisture by capillary action], moving it to the outer materials of the shoe where it is released into the outside environment.
• Acrylic cushion sock fabric maintains resiliency and provides a more natural yielding, forgiving, dynamic environment for the foot (like walking barefoot in grass or sand).
• Result: More protection, more comfort.
