I'm less unhappy with my cheap heated socks as I think I'm learning to live with their limits and my expectations.
I'm now setting them on low before leaving the house, this keeps my feet fairly warm for the drive to the hill, about 20 minutes. I leave them on low and my toes get cold but not to the point of needing to take a break. Now I need to crank them up to medium for a run or two and see how that works. My problem earlier was going to medium and then the balls of my feet would start to hurt so I think the key is limiting the medium setting unless its really cold.
I fairness to the socks one of the days I had a problem was skiing early and then working the greenway carpet where my feet weren't in the cold wind. The socks I have are Ororo, and I think I purchased from Walmart.
I still think if you want to ski when its really cold, Hotronics are a better bet, but if you want a bit of warmth on marginal days (0 F in the morning) these are OK.
