Halcyon has a product that works pretty slick for drysuit divers to keep the air out of your boots. They are called gator wraps. Check em out.

Yeah, I've never felt the need for gators since my drysuit fits pretty good in the legs. I think for those with drysuits that fit a bit baggy in legs though the gators are a good solution. JoelW has the Halcyon gators and they seem to work well for him.

Here is a link to a past thread on gators.
