Winter is just around the corner so I though I'd share a little trick I've found for helping keep my toes warm in the cold: tyvek toe warmers.

Years ago, a cycling buddy told me to use plastic baggies on my feet to help keep my toes warm in cold weather. It actually worked pretty well, but the bags were pretty much destroyed after a ride or two, necessitating frequent replacement -- plus the bags tended to make my feet feel clammy.
