1 hour

This is about the amount of time I can use a regular mtb shoe and heavier sock before the toes start to go cold. Right around 20 something degrees this morning on the commute. Nothing clears the head better than a cold day commute. Although in the interest of time I been taking the busy road, which seems to taken away from the clear head. You know the noise and toxins and lousy drivers. I never quite get while some people think you have to accelerate so hard to pass something going around 20mph. Especially when there is a shoulder. I could probably rant on and on, but in somewhat of a hypocritcal way, I am a lead footer. But Also from watching pro races in person I see what drving with bikes is about.
