For the last couple of years streets here in Europe were flooded with 270s. Everyone and their momas had them. And just as quick as they came, they went away.
Yes 270's were very popular in Sweden too but more amongst people aged 20+. At least I didn't see them often on kids. But my observation was the same for NMD's, they were extremely popular one season then went away as quickly as the 270's. I can't really argue about Adidas because I don't follow Adidas much but looking at StockX I see that some NMD's have very high bids.
