I call it the 5 since this is usually the timeframe that they start releasing a new UltraBoost, plus there's enough of continuity in design language (even if it looks horrid in the new silhouette...) that it's another product in the same lineage. It's possible that things would change, or maybe Adidas quietly separates the UB2019 as its own thing due to the negative initial impressions. You did good with the 4.0 selections. I'm still deciding on whether I want to cop the City Lights multicolor, the Spearmint multicolor, or the white-base multicolor (by far my favourite of the three).
That cage just screws everything up. Like even with basic and traditional colourways, it does nothing.
It has the feeling of an incomplete prototype as opposed to a stylish sneaker.
