Brian-

I missed your original comment about the neoprene feet being too tight. If that's the case, and if you're willing to spend a little more, Simms used to have a program where they would replace the feet on any given pair of waders for a modest amount. I know my brother had to take advantage of that some years ago, due to needing a bigger size foot than what was available with the wader size that fit him. Simms stitched/taped/sealed larger size feet and all was good as new. You might email or call them and see if that service is still available and at what cost. Given how little you guys paid for those, you'd still be way ahead of the game.
