These vintage Nocona cowboy boots are labeled with model number 39200 and feature genuine leather construction Nocona Boots handmade in Nocona, Texas. Size and Fit Identification The markings on the leather lining indicate the following: Size: 10 D — This is a standard men’s size 10 with a "D" (medium/regular) width. True to Size: Vintage Nocona boots are generally considered to run "true to size" compared to standard dress shoes. Key Fit Markers: A proper fit should feel snug across the instep (the top of your foot), while the ball of your foot should sit at the widest part of the sole. Slight heel slippage is normal and necessary in new or stiff vintage boots until the leather softens. Production Era: The "white label" on the pull strap and the horizontal stamps suggest these boots likely date from the 1950s to the 1970s. After Nocona merged with Justin in 1981, they eventually transitioned to red tags and different labeling. Style Number: The number 9905 identifies the specific style or model of the boot. Secondary Codes: The alphanumeric string 3220C contains internal factory codes. In many vintage Nocona models, these codes represent the specific leather type, color, and shaft height used for that production run.
