UGG Leather Chukka Boots Size 8.5?

UGG “Leighton” Black Leather Chukka Boots. Size 8.5?? Sadly, the material and size tag fell off. I think they were 8.5, but they could have been 9. If they’re 9, they’re a small 9. Please refer to photographs for approximate measurements. I’ve also included a photograph of the shoe versus a known UGG size 10 loafer for reference. The measurement of the inside of the shoe from the area of the big toe to the heel) is about 9”, but I was unable to adequately photograph that. Finally, the removable insole of the shoe identifies the insole as 8.5-9.5, but there is no specification of whether the sizing is US or otherwise.  The photographs show exact item you will receive; no stock images. Good condition. There is routine wear, but no rips, stains, or tears. Of course, as noted above, the tags have fallen off.
