RU Outside Sonic SplitWeight(tm)Sock.
Here it is. Our baby...The goods. The right stuff. The Sonic SplitWeight do it all sock. All over our website you'll find reference to wicking materials and various fabric weights. SplitWeight!!!
The Sonic SplitWeight sock provides "just what you need right where you need it". Thicker in the heel and toe area, a bit thinner in the middle. Knit perfectly to stay put, merino wool for comfort, and most important, moves the water away from your foot. By the way, this last point is useless unless your boot liner can handle the moisture. See the BT Boot and you're covered...
