NEOS insulated overboots with uninsulated leather boots inside will take me from summer down to pretty cold. Used them in AK back in February and was quite impressed with them.
Those look pretty nice!
Worked a lot better than I expected and for what I do fit my uses at a better price point than more expensive pac boots. During our gun season in November, I hunted in tennis shoes under these things. Feet never got cold, though we only saw lows in the 20s. That said, a boot/shoe that fills the over boot more makes them a bit easier to walk in. The tennis shoes alone weren't bad, just not quite as good as my hikers that are a tighter fit.
