In Georgia it's not worth the expense of the winter boots....tuff it for a day (engage Rule 5) and it will warm up tomorrow. I did keep an eye out on eBarf this past spring for some used boots. I got a pair of Lake boots for $53 w/shipping after cold weather was gone.
It hasn't got lower than the mid thirties around here yet. I did the best I could to get an idea of how they'll work out. I went for a ride with nothing but a pair of Icebreaker Ultralite Hikers. You can see through them. That was the first time in years that my feet have been comfortable in the mid thirties---not matter what I had done before. I wear a 43 and bought a pair of 44's, toes have wiggle room with Icebreaker Mountaineering socks.
I'm feeling good about the winter day that we might have to face in Georgia this year!!!
