A couple things I would consider if your pain started after switching to a flat boot.
1) Is the toe box wide enough? Does your forefoot have enough room to spread your toes?
2) Did you take time to transition or prep your feet to transition to a zero drop boot?
A great resource is Whole Body Bearfoot.
