Reposhing this item I Loved it, but ready to rotate for something new. Preowned Ultraboost 20 low-top sneakers High performance without the fuss. The adidas Ultraboost 20 sneakers are all about fusing together practicality and comfort, thanks to their flat rubber sole and Flyknit construction. A contrasting 3-stripes logo on the sides adds a bold touch to its black and white design. Questions? Leave a comment below!
