Here's what other sites are saying:
Thorlo ski socks provide maximum density and resilient pads to optimize comfort and protection for the novice or expert skier alike. Extra padding at the ball and heel reduces the destructive forces of foot strike. Patented, anatomical Magenta Line(R) design interfaces between the foot's surface tissues and boot's interior surface for maximum protection. Control Zone(R), a low-density pad in the arch area, allows boots to snug closer to feet to facilitate better control. Shear Zone(R) protects feet from activity-specific stresses, blisters and calluses which are the root causes of most foot problems. *Offer not valid for sale-price items ending in $._3 or $._9.
