The "Uncaged" moniker indicates the absence of the external plastic heel counter found on the traditional Ultra Boost model. This design choice enhances the sleekness of the sneaker and allows for greater freedom of movement around the ankle area. The collar of the adidas Ultra Boost Uncaged Triple White (2017/2021) features a sock-like construction, which minimizes friction or discomfort during wear.
The Boost midsole is a signature feature of the adidas Ultra Boost Uncaged Triple White (2017/2021) that the StockX team appreciates. This cushioning technology provides energy return and comfort, allowing for a responsive and supportive stride. The shoe took an initial market price of $180 upon its release on 7th June 2017.
