I'm trying to stick to ~10 mi each way commute to work (~20 mi total). If I'm early, then might do a few extra in Central Park. Yeah, yesterday was cold and was 11F for me in the morning. Afternoon felt like a heat wave at 28F. But 11F was pushing it a bit for me. Toes were getting numb later in the ride but was close to work so not a big deal. What do you guys wear in low temps when two wool socks, shoes and shoe covers are not cutting it? Maybe can go ghetto and try the plastic bag on the feet again...
