For what it's worth on the boots front:

I made this: the S-ACE ones have the same lower, but the upper doesn't match, whilst they look a better fit in terms of total height under the flight suit to the other ones, the sides and front aren't quite right at the top and the heel doesn't curve inwards.
The Mucker seems almost identical, with the exception of needing to cover/remove the Hi-Viz tape on the heel. It's just a question of is it too high up the leg or not, which is hard to see in the screenshots.
But from what I can see here:,

Poe has short ones too, but Oscar Isaac is a size 10, so he's not wearing the women's boot so they must be available somewhere.

Just I know some people have bought the S-Ace already and I'd hate for them to end up finding they couldn't use it in the stricter realms of the costume world e.g. RL.
