ES Fulton, will they stretch more?

[DGP]

Ok, so I've worn my ES Fulton Line Drys around inside for a total of about 4-5hrs, with a belt, just sort of around the house. Right now, they are still a really good fit. I just want to know if any stretching that would happen will happen during this initial time, or if there is still a chance of more. I ask because I only have a couple of days if I want to exchange for a 31. Like I've said before, I got my RRDS in a 31, and washed them on cold with hang drying after about a week. I plan on washing these on cold and hang drying in a similar time frame. These aren't quite as uncomfortable as those during the first few wears.

If they aren't tight they won't stretch as much from wearing...
