You mean literally getting your foot out of the bootie when taking them off?
If so, I suspect your booties are too small. They may not seem like it when dry, but get them wet, and you get a little sweaty inside them, and they'll almost suction to you.
I've had various pairs where the booties have been more snug than others, and had more difficulty getting them off...One pair of closeout William Joseph's sticks in my memory...I think they acknowledged an issue with bootie size on that model and I got them on a significant discount online and rolled the dice. Yeah, the booties were too small and difficult to get off, though in general they were a good pair of waders. Got 2+ years leak free from them.
FWIW, the LLBeans I've had have had consistently roomier booties. (They're cut roomier all around for a given size, which I like...more airflow around you, makes you sweat in them less.) I've had to watch the wading boot size to pair them with and go a size bigger at times, but from a comfort perspective they're better, and the booties slide on and off easily. I tend to keep a nice pair of Beans as my flagship pair for bigger water and wading deeper, and then rotate out a disposable $100 or less beater pair for small stream brush busting fishing.
Try looking for bigger booties on your next pair, or order a size larger since the bootie size generally runs proportionally to the overall size of the wader. A little too big is better than a little too small when it comes to waders IMO, so I always error on the bigger size when I'm not sure.
