Insole is 10 3/8 long and 3 3/8 wide. These are custom sized Wesco Boots.

I figure these are about a men's 7, EU 40 or Women's 8.5-9. My friend is a men's 8 and he could get them on, but they are too short. My daughter is a women's 8 and these are large on her.

For what ir is worth, the bottom outsoles measure 4.5" x 11.25", but I recommend comparing insole size! Thanks for looking.
