Ah, those are from BugzLife's "Stellar Knights Suit.

I do a lot of "mix and matching" along with "frankensteining".  Like the boots, the foot and toe sections are from the Tail Gunner set, but the ankle section is from the Stellar Knights set.  By giving the same red leather shader, they "blend" into a single piece of footwear.

Sincerely,
