Generally a few ways to handle, make sure you ride with a cleat/pedal that has a wide platform, make sure the cleat is properly positioned, make sure your shoes are comfortable but not loose - you told want your foot rocking around inside the shoe, and wiggle your toes, alternate clipping right then left, rest your feet occasionally.
The pain starts at the top of my butt, travels down the length of my leg and ends at the base of my toes. Cycling just makes it more prevalent in my feet. But I'll search on neuroma.
