I’ve been duck hunting in Simms G3 riparian pattern stocking foot waders and a pair of cheap frogg togg wading boots for two seasons now.
Pros: Much more comfortable to walk long distances in, footwear is more secure in mud.
Cons: You can only layer so much under them, feet get cold easy.
If someone made a stocking foot, neoprene 800g with some insulated wading boots that would be the ticket.
