+100

I rode for years without shoe covers and couldn't believe how big a difference they made when I finally got some. I eventually figured out that layering your tights OVER the top of the shoe covers keeps rain hitting your legs from running down into your shoes. This obviates the need for the plastic bags inside for all but the longest rides.

[I find the plastic bags clammy and uncomfortable. My feet get as wet from sweat as they would have gotten from rain - but at least they're warm. Price is right, too...]
