Dr. MartensDr Marten Men's Vegan 1460 8 Eye Boots

I recently bought a pair but they only have leather insoles that cover half the length of the sole (the rest is fabric). Does this mean they are fake?

I had a size 8 before in the taller dr. martens and they didnt' fit well with my inserts. would a size 9 be too big? they don't have half sizes.

Is the 5,6,7 size options, are they uk or us sizing??

Would you say these boots are comfortable for someone with a wide foot?
