you must have some hot blood. id say maybe if you walk every now and then but 3 to 10 hours on a stand your feet are gonna get cold. i say ditch all those ploy pro liner socks. go with good wool against your skin. polt makes my feet feel clamy. heat packs are a must. i also agree about keeping you core body warm like chest and your back. it will take care of your hands and feet. i saw a show on the discovery channel about just that. they stuck a guy in a refridgerated room and when they stopped heating his chest his hands went numb. you could sew some pockets in a fleece shirt and load up the heat packs. or just buy one of these like i did. http://websearch.cs.com/cs/boomframe...p%253Fid%253D3
