CheapestAdidas ULTRABOOST 20 “VAPOR PINK” (FV8358)€27
Priciestadidas Ultra Boost 1.0 Arizona State (AQ7848)€3.609We always compare the lowest price a colorway is currently on sale for somewhere: the cheapest entry point, usually for one specific size. The comparison stays within the same age group, because a kids size (TD/PS/GS) is priced differently than an adult size. Because the price varies per size, your size may come out a little higher. To keep the comparison fair we leave out the most and least expensive two percent — the resale outliers, and the price axis is logarithmic so both the cheap and the pricey end stay readable. We refresh the numbers several times a day; last update 8 Sep 2026.
Hypescore × price
Hype doesn't have to be expensive. Each dot is a Adidas UltraBOOST colorway (of the 1595 with a Hypescore): the further right, the more hype, and the higher a dot sits, the cheaper the sneaker. This sneaker is the photo with the red ring (Hypescore 16). Below the RRP they're called meltdowns: top-left the quiet price meltdowns (cheap, but little attention yet), top-right the radiating meltdowns — lots of hype and well below retail, the hottest deals. Above the RRP sit the grails: bottom-right the radiating grails (loved and pricey), and bottom-left the potential grails — pricey with little hype. That can simply be too expensive, but it's often where fresh drops and collabs appear that are too new to have gathered grail votes; their hype still has to build.
