About the adidas UltraBoost Summer.Rdy "White Solar Red"
Summer.Rdy is the adidas label for hot-weather construction, applied here by loosening the knit so air passes through it and by cutting back the overlays that would otherwise trap heat. Cloud White dominates, which also helps, since a pale upper reflects rather than absorbs sun. Core Black grounds the heel and sole, and Solar Red, a bright orange-leaning red, takes the accents and gives the shoe its only warm note.
Everything below the upper stays familiar: a laced midfoot cage locking the arch and a full-length Boost midsole of fused thermoplastic polyurethane pellets. Retail was $180, level with the standard shoe, since the seasonal treatments changed material and venting rather than adding hardware. Summer.Rdy sat opposite Winter.Rdy in the same catalogue, the two labels bracketing the year and letting one silhouette cover conditions a single upper cannot handle.
