I'm heading into my first cold weather. I wear Shimano mountain bike shoes (size 46) with SPD clips. So far my feet haven't gotten cold, nor my legs (I wear Nashbar leg warmers with my Ultra bibs). But the temperature has only dropped to the low 40's so far. I may as well get prepared - the temperatures here in New England will be dropping a lot very soon.

I get confused when I look at booties: should they cover the rear of the sole, is neoprene the best material, are zippers better than velcro? Or can I go cheap and cut a hole for my cleats in regular overshoes/overboots?

Is there anything else on this subject I should be thinking or asking about?

Thanks, as always.

PS - Peak colors have passed but the NE scenery is still spectacular. I've had four gorgeous rides in the last four days - two hundred miles. I sure am lucky.
