I bought a pair of their fett boots for my Super Trooper, I wear a size 12, I ordered a size 12. Upon arrival I had the fight of my life attempting to get my feet into them, the design essentially layers neoprene on top of stretchable fabric, eliminating any stretchiness that once existed. I cut out that neoprene layer from inside of my boots and they fit like a charm now. If you can spare the money, manofwarstudios' are $70 more (only $40 more if you include shipping costs on the RL boots), and I have his 2-piece flight suit, leather belt, and gloves, his work is superb and his communication is fantastic, he's also an active member of TDH communtiy.
