Nunn BushMen's Cam Moc Toe Casual Lace-up with Comfort Gel and Memory Foam

Hi, do you know for sure if x-wide width is equivalent to 2e, 3e, 4e, 5e or 6e ? thanks !

where are these made?

Is the sole of the shoe flexible or stiff? I have Hallux Limitus and I'm looking for stiffer shoes to prevent my big toe from moving.
