adidas Ultraboost 21 COLD.RDY Core Black / Core Black / Carbon (S23755)

Het is koud buiten, en het regent ook nog, maar je vindt dat je het niet kunt maken om binnen te blijven. Gelukkig is het met deze adidas Ultraboost 21 COLD.RDY schoen een stuk makkelijker om de deur uit te gaan. Het isolerende bovenwerk houdt water tegen om je voeten warm en droog te houden. De loopzool van Continental⢠WinterGrip⢠Rubber biedt stevige houvast tijdens steile afdalingen en op gladde traptreden. Responsieve Boost-demping geeft je een energiek gevoel dat je eraan herinnert dat je altijd nog iets verder kunt gaan – misschien vijf stappen, maar misschien ook wel vijf kilometer.

Price distribution Adidas UltraBOOST

We compare this sneaker's price with the 1596 other adult versions of the Adidas UltraBOOST that we track. At a lowest price of €75 this colorway is cheaper than 98% of those 1596 versions. The group median sits at €178, with resale outliers up to €3.609. The chart shows exactly where this sneaker falls — the black marker — among all the others.

We 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 28). 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.
