First I use to have the sweaty foot problem, I quit smoking and the feet quit sweating and stopped stinking to. Any way I use grabber toe warmers, they are flat and work great try grabberwarmer.com. I bought a pair of cheep KMart moon boot looking boots lots of room for double socks and wiggle room. I think the loose fit is most important, allows for air space in the sock material that holds the warmth in. Good hunting to you Striper Phil
