I ordered a couple of these to replace the ones I already have (Ultraboost 19). The picture shows a pair of black Ultraboost 20s, but it's actually a 2017 Ultraboost 4.0, three years older than the model pictured :(
Pros
Very convenient.
Cons
The product was great but I tried to cancel within 30 minutes of purchase and they couldn't do anything for me.
