Brian,

Here were some tests done on combat boots in the 90's. http://www.dtic.mil/dtic/tr/fulltext/u2/a257293.pdf

Page 20 and 52 describe the water immersion testing. The longest time done was 15 minutes. Boots with leather tops had no moisture come through. The boots were immersed to the bony sides of the ankles.

If the water was over the top for a long time, water would most likely fill the boot. But for brief periods of a few steps, I didn't notice any coming in. Keep in mind, the top is pretty snug because the lacing system goes around the ankle and there is padding to make a tighter seal.
