They have been washed. The size is 35. I am a 22.5, so I think it's around 22-23. The heel height is about 9cm, and the front is about 4cm. As you can see in the 3rd and 4th photos, the color of the heels is slightly different on the left and right sides, but it's not very noticeable when worn since it's on the feet. If you are concerned, please refrain from purchasing. Color: Brown系 (Brown-based) Stains, tears, odors, etc.: Yes
