Frye 77400 mid calf boot, Engineer 12R Black.
Unlined, Rubber sole, Goodyear welt, 9 1/4" shaft, 1 1/2" heel height.
Made of greasy leather, this boot gets even better with age.
These boots are made in the USA and are available in women's size 6.
Overall good condition, soles have a good amount of rubber left on them.
I use Pure Polish natural leather cleaner & conditioner on them.
