Unknown Vintage USA Made Leather Work Boots Aero Glide Soles Brown Men's 8.5D?

A quality pair of vintage American-made leather work boots with Aero Glide oil-resistant soles. These boots feature full-grain brown leather, brass eyelets and speed hooks, removable leather kilties (false tongues), and durable stitched construction. The leather has developed an attractive patina through years of honest use while remaining soft and substantial. The interior stamp reads: Made in U.S.A. Leather Upper The size stamp is faded and difficult to read. It appears to read 8½ D, but I cannot guarantee that interpretation. Please rely on the measurements below and compare them to a pair of boots that fit you well. Approximate exterior measurements: Length: 11.75 Width: 4.25 Height: 8.75 Condition is good vintage. The leather shows normal creasing, scuffs, scratches, and color variation consistent with age and use. The soles retain good tread, and the boots remain solid and wearable. The removable kilties show some edge wear. Please review all photos carefully as they are part of the description.
