Fly London boots, new in box, size EU 41 (UK 8). Black leather.
The Fly size chart (see photos) says this is an AU 9 (I usually wear AU9, i find these roomy but not too big - use the measurements below to check your fit).

Here are some approximate measurements:
Heel 3.5cm
Length floor to top 39cm
Sole length 28cm, length of foot of boot (outside) 26.5cm
Across top of leg 19cm (tape measure all around outside at top is about 40cm)

Never worn, as you can see in the photos.
