I also found it here for $521, from some company that seems to be based in California. I hope that means you have to save up less. http://www.itmustbetime.com/hamilton-men-s-h70585733-khaki-field-black-day-date-dial-watch.html
If you lace them securely from the start, you have a chance of having them form to your foot in a manner that doesn't shift. Once they start to slide to the side, it's probably creasing that's not (easily) reversible. At that point, you could have a cobbler stitch one side of the tongue to the upper. It's pretty simple for them to match it up to a stitch line already present on the outside of the boot. Disclaimer: This is not science, but my interpretation.

I don't think you're alone in that sentiment. Now, I haven't completely cast the brand aside, as I appreciate Eric's style and the one-man nature of his operation. However, the expediency of his shipping process has caused me to reconsider ordering a few items, especially as gifts.
