Replying to Boot fitters of NS, whats the strangest problem you've had with a boot fit and how did you solve it?

Been boot fitting for a few months now and had an elderly gentlemen come in with charcot foot (the metatarsals soften, arch collapses and end up fusing together leaving a large boney area on the inside of the foot)

note: it's a grim google search

ended up putting him in an APEX boot as it was the only one he could put on comfortably with a reverse arch foot bed to support it in the boot. (with help from tom on messenger, thanks!)

Curious as to other peoples stories, could help with sharing problems and solutions.
