Nike Vintage 1990 Trango Hiking Boots

I've seen them called Caldera but I'm pretty certain they are Trango's. I got them directly from the Nike Factory in Beaverton, OR, I believe in 1990 or 91. They say size 6, but they fit small, like 5.5. If they still fit I would keep them. I love these boots! No rips or tears in the fabric. Light wear on the tread. One of the metal eyelet hooks upper right is missing. I never used it anyway.
