• Midweight padding in the heel and ball protects foot from shear and impact.
• Low density padding in the shin and lace pads protects the leg and foot from boot pressures.
• Spandex in the arch for added comfort and better fit.
• Ventilation panel provides enhanced wicking.

Fiber Contents: 68% Thermolite®, 15% Nylon, 2% Spandex

• 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.

Thermolite® by INVISTA is an excellent wicking fiber designed with an air-trapping hollow cross section that produces amazingly warm and comfortable OUTDOOR and SKI Thorlos. Thermolite® protects against overheating and keeps you warm even when wet with perspiration.
