I would like to buy a new pair of boots before Sedalis that are vented well enought to actully feel the air move around my tootsies, or at least on my ankles.

What do you use that really work? I have looked at the Sidi Air boots with the perforated Lorica but question how much air will actually move through them.
The BMW Airflow looks interesting too.

Mid-heigth is OK but not a low cut 'shoe' type as I want ankle protection.
