buckskin Italian leather boots Vintage calf high from Arnold Churgin size 7.5 38

I love these buckskin colored, buttery leather boots with a tan or buckskin hue. The truth is, I can get them on but with some weight gain, they are a bit too tight on my calf. I can get them on as you can see, but they are no longer comfy on my calf. Excellent shape with only gentle signs of wear. I am a true 7.5 US and these boots fit me like a glove (well, before the calf thing….) 15” calf 3” heel 16” top to bottom of heel length of sole 11”
