Well, it was about 70 degrees F here today, and sunny--perfect BF weather. Spent the whole weekend BFi. Tomorrow it's back to the workplace, and shoes again (ugh). I can hardly wait till the end of each work day so I can shuck the shoes and socks and drive home BF and stay BF till I have to be at the salt mine again, LOL.

I walk barefoot everyday including the winter. I have suffered frostbite and frost nip when out in temps below 12f. I am now more careful when walking and keep an eye on the color of my toes, red and pink are good colors, as they show circulation. When your toes turn white you need to rewarm them as they'll soon begin to freeze. I will return to a warm place or slide some shoes on and continue walking. When my toes warm up I start snowfooting again. Wet slush is the hardest to stay warm on because of it's conductivity. My circulation can't keep up with the rate of heat loss. 30 minutes on the snow can be comfortable if the conditions are right - sunny skies - packed snow - and good aerobic activity. Circulation is the key and controling the rate of heat loss. I expand my limits safely so I can barefoot 12 months a year.

Being from Canada, I've grown quite accustomed to walking barefoot in the snow. I can usually last anywhere from 20-35 minutes depending on the temperature and the type of snow.
I try not to do it too much though, as it can cause health issues in the winter to do it too often.

Whenever I can. I love the initial shock and then the loss of feeling as my feet slowly sink into numbess. Then its time to go in.

Barefooting in snow (especially the fresh, lightly packed variety) is marvelous. Like you, I'm good for 5 minutes or so at a time, but I'm looking to increase my tolerance. The intensity of the cold is very appealing, and I find the cool vibrations refreshing for hours afterward, especially on these afternoons of sunny mid-40s when I would normally be out barefoot anyway.

It's around zero degrees F. here.
I take the garbage out to the curb, and walk out to the street to check the mailbox barefooted.
Below zero, though, I slip something on my feet (learned about frostbitten feet at minus 20 F. the hard way when I was 18!)
