Worn twice for few minutes black Birkenstock Boston uk 37

I purchased these BNWT from Vinted recently. I dont suit black hence the decision to resell. I wore them twice in the car to drive to yoga, a minute walk either way and did this twice. I’d guess they were outside for 4 mins total approximately. They are mint condition, I’ve tried to reflect it in photos but of course if you’d like more photos please ask. I usually wear a uk 5 but with Birkenstock I always need to size down. On the box it says size is 37/uk 4.5. They fit me perfectly as someone who is usually uk 5 They are black suede and I did spray the with suede protector, they look exactly the same but are protected which is a bonus They come with the original box. I didn’t keep the tags but can show a photo of the original listing that I purchased from. Any questions please ask!
