Sounds like a classic case of your hiking boots being too small and/or your feet swelling a lot during your hike. Very common in people who hike or run long distances. Go up a full size in boots, or at least try to find a pair that has a significantly bigger toe box. I knew a guy who was an "ultra-marothoner" (where they run/walk/keep moving for 24 hours, yeah, crazy). He had the same problem due to swelling over the protracted times. He would cut the top of the running shoe's toe box off and run that way. Where there's a will there's a way, I guess.
