The upper of the Ultra Boost 4.0 Clear Orange (Women's) is constructed using adidas' signature PrimeKnit material. This lightweight and breathable fabric offers a flexible and adaptive fit, conforming to the foot's shape. The shoe features a sock-like collar design, which enhances comfort and provides a secure fit around the ankle.

The shoe incorporates the Boost cushioning technology embedded in the midsole. This responsive and energy-returning cushioning system delivers a plush and comfortable ride. The adidas Ultra Boost 4.0 Clear Orange (Women's) incorporates a supportive cage design on the sides, which adds structure to the upper and features the iconic three-stripe branding. The Torsion System in the midfoot enhances stability and support, helping to maintain proper foot alignment and reducing the risk of injuries during runs.

What our experts at StockX truly appreciate about the Ultra Boost 4.0 is the Fitcounter molded heel counter. The feature supports the rear of the foot, ensuring a secure and stable fit, particularly during the running gait cycle.
