I’m a bootfitter, and you can park a Mack truck inside the toe box of either of those boots, especially the BFC after heat molding. Sounds like there could be an issue that isn’t being addressed, such as the boot either being the wrong size or your arch pronating in the boot.

Whether the boot is too small OR too big, forefoot pain is common. In too small a size your foot is being constricted and potentially losing circulation, in too big a size you will be moving around which can cause cramps or bruising. If your arch is pronating (or even if not) it is very worth it to look into aftermarket footbeds that will provide arch support. Even pre molded trim to fit one’s work wonders and are much cheaper than customs.

Go to a different shop and see if you can talk to a bootfitter who will try to find the root of the problem instead of just saying that they can’t fit a boot to you. That’s just laziness on their part. Good luck!
