I was wondering if anybody else has experienced different flight characteristics (sitfly) by wearing different shoes. I used to wear cross-trainers that were streamline in shape. A few days ago I tried a flat-bottom casual/dress shoe from KMart. Its flat, square profile helped me cut through the air like a snowboard. Stable loops, on-heading turns, responsive control. It was a Night & day difference. Is there anybody who can comment on this?
