Wish these worked better...
I'm afraid these aren't the answer to dry feet I was looking for. I've been riding them for several months and haven't had as much success as other reviewers. Went for a 2 1/2 ride yesterday in light- to medium heavy rain & mid 40's temps here in Seattle.. At the end, my feet were quite wet, which has been the case most of the times I've worn these in the rain. I believe much of this wetness came in through the neoprene at the top of the overshoe.
In addition, I've found that the reinforced hem around the cleat hole on the bottom of the shoe is a little thick. If I don't pay attention, using my Shimano cleats, this hem can get underneath the front of the cleat and make it difficult to clip in.
I concur with the advice to the double-check the sizing. I wear a 43.5 in a Sidi (Genius 6.6), and I purchased a size L. The label inside the overshoe says L - 42-44.
