Missed this on the first pass, regarding Poe wearing the "short" version of the boot...
The site that sells these posted later upthread, has them up to US women's size 11, which is pretty much a men's size 10. So it's entirely possible Oscar's wearing the women's boot in the Visual Dictionary pic...
Also, just realized from the VD picture of Jess Pava, there's a callout indicating her flight suit is "Interstellar Orange" in color. I can't help but wonder if that's a tongue-in-cheek "Swarzifying" of "International Orange", a real-world color often used for protective clothing in military, first-responder, and similar attire. And, conveniently, available in 1000-denier Cordura. I'll get a swatch next time I'm at Seattle Fabrics. Anyone wanting to check it out firsthand for suitability, send me a PM with your address and I'll mail off a bit for you to examine.
