Are you zigzagging below or through the elastic?

I am zigzagging through the elastic - but just through that bottom part. The way that I do it, is I stretch the elastic and stretch the boxer briefs together, I hold it all and just zip around. When you let go, the zig zag will tighten along with the elastic.

By the way, when you serge your elastic onto your boxers, you will end up using a little less elastic than you would if you were encasing it. This is because the serger will stretch the elastic a little. I usually plan on about a half inch to an inch less than the pattern normally would call for. HTH!
