Adidas x Marimekko collaboration UltraBoost sneakers featuring a flower pattern design. - Brand: adidas marimekko - Model: UltraBoost - Color: Black/Beige/Flower Pattern - Material: Knit Thank you for viewing. I bought these because they were cute, but I'm selling them because I don't have many opportunities to wear them due to childcare. I've worn them a few times, and the rubber part is slightly yellowed. Please refrain from purchasing if you are concerned about this, as they have been stored by a private individual. I have intentionally opted out of the authentication service. If you would like to use it, please let me know and I will change the settings. Model Name: ULTRABOOST
