YRU Dreamer cloud thigh-high boots size 8

These are brand new- only tried on in our house for a few hours, but had them stored in our garage area until recently and my partner accidentally splashed a bit of mud on them one day coming through the door. I managed to get most of it off with a wet cloth, but there are a bit of residual spots, which I have shown in pictures. It is not super noticeable, and you could probably get the rest of it out with a soft wet cloth, I haven’t tried since. There is also a tiny spot of manufacturer’s glue near the top of the inside of one boot, which was there when I got them. This all reflects in the price. These are a size 38, I am a size 8, and these fit me comfortably. There is stretch in the leg part.
