I just remembered the lesson I learned my first season of racing. If you have to ride when it's pouring and it is too warm for full leggings and gaiters, shoes are going to get wet. Do yourself a big favor and provide a means for that water to leave. Traditional cycling shoes had 1 to 3 holes at the front of the sole between the toes and front of the ball of the foot. I never thought about those holes. Rode my first "real" (open) race in a steady, not light rain. Rain started 10pm the night before and was still going when we finished. By the end of the first hour we were completely soaked. 3 1/2 hours to go.

I never thought about my feet. But after the race we all heard loud and clear the complaints of those whose shoes didn't have those drains. They spent hours squishing water around inside their shoes at race RPM. And not a single one was a happy camper. (I've been known to drill those holes in shoes that did not come with them.)
