You might be right. A shame they're absurdly expensive but it would be pretty great on those occasional mornings where my toes just turn into blocks of ice!
I have had issues with cold toes even with temps in the teens. I got a pair of the Lenz 5.0 heated socks with the toe caps and while the price was painful I cannot imagine skiing without them. Having those socks have translated into many more hours of skiing instead of sitting in the lodge. If you can swing it I really recommend them for anyone with cold feet issues.
