Sounds radical but this is how I did it and it works perfect. Mind you I only needed to do this ONCE and it has never been a problem since. I took the shroud off and put it on the ground bending the offending part back in more than it needed to go. With the pressure on it, I took a propane torch, (yep a propane torch) and waved it quickly across the corner a few times until the corner started to get soft. I didn't melt it, I just got it soft enough to bend. Once it was curved in, I let it cool and put it back on the bike. Now it stays really tight against the bike and never ever catches my boot or anything else.
