They are better than a lot of shoes since there's no mesh to let the water in. However, they're also warmer when the sun's shining for the same reason. BTW, I took the first ride with full mudguards on my bike (including front mudflap) and my shoes were completely dry!
full length guards defninitely the way to keep surface water off your feet - think I prefer wet feet though to the full-guarded look though ;-)
