Mt Whitney Zone Forums General Discussion Any thoughts on foot preparation?

I often put 30+ miles a day without issue. I use an Under Armour Military boot sock as a liner and a pair of thick merino wool socks. Sometimes I start a hike with a mid weight wool sock and change into thicker socks for the downhill. If you check my pack during a long hike you'll find more socks than food. I'll often rotate two pair of liners and three pair of wool socks, changing every few hours. Sometimes after a brutal downhill I'll need some motrin for the foot pain, but haven't hade problems with blisters or hot spots in awhile....................................DUG
