Adidas Ultraboost 21 Review

The Adidas Ultraboost 21 is a running shoe that has garnered attention for its blend of comfort and performance. Designed for both serious athletes and casual runners, it features several key technologies that enhance the running experience.

Comfort and Cushioning

One of the standout features of the Ultraboost 21 is its Boost Technology, which provides excellent energy return. The midsole is notably thicker than previous models, claiming to contain six percent more Boost capsules. However, some users have reported that while the cushioning is soft, it feels firmer than expected, which may not suit everyone’s preference for a plush ride.

Upper Design

The shoe utilizes a Primeknit Upper made from 50% recycled materials, offering a sock-like fit that is both breathable and flexible. The snug fit can be a double-edged sword; while it provides a secure feel, some users have experienced discomfort due to the tightness, particularly in the toe box. The design includes ventilation holes that enhance breathability, making it more suitable for warmer weather.

Outsole Performance

The Continental™ Rubber Outsole is designed for durability and grip across various surfaces. Many users have noted that the outsole holds up well even after extensive use, showing minimal wear after running over 100 miles. However, concerns about the durability of specific rubber panels have been raised, particularly regarding their potential to detach during use.

Weight and Fit

Weighing in at around 330 grams, the Ultraboost 21 is considered heavier than many other running shoes, which may affect performance during speed work. The fit is generally true to size, but those with wider feet may want to consider sizing up due to the narrow toe box. The shoe features a high heel tab and a one-piece construction that makes it easy to put on and take off.

Overall Impression

While the Adidas Ultraboost 21 is praised for its aesthetics and comfort, it may not be the best choice for everyone, especially serious runners looking for a lightweight option. The shoe excels in casual wear and light runs, but its weight and fit issues could deter those seeking a performance-oriented running shoe. Ultimately, it remains a stylish choice for everyday use, but potential buyers should weigh their specific needs against the shoe's characteristics.
