Adidas Ultraboost 5X

The Adidas Ultraboost 5X marks a significant evolution in the Ultraboost line, delivering a lighter, more responsive, and more comfortable experience. Designed for runners who prioritize cushioning and smooth rides during daily training, these shoes also stand out for their modern urban style and high-quality finishes—making them a truly versatile option.

Primeknit upper:

The upper features a soft, stretchy Primeknit material that wraps the foot like a sock. From the first wear, comfort is immediate: no annoying seams or pressure points, making them ideal for anyone seeking a shoe that feels like a second skin. The design especially benefits those with wide feet or who need extra toe room.

Its flexibility also makes them easy to slip on and off, a welcome feature for everyday use. While it’s not the most breathable upper out there, it provides adequate ventilation in mild conditions.

Light BOOST midsole:

One of the biggest improvements in this version is the introduction of Light BOOST foam. Compared to previous iterations, this compound is lighter and offers greater compression without losing responsiveness. The ride feels soft yet energetic, adding a touch of bounce without sacrificing comfort.

This kind of cushioning is perfect for long runs or relaxed training sessions. Even after distances beyond 15 km, your feet stay fresh and fatigue-free. However, it’s not built for speed workouts—on faster runs, the shoe can feel a bit sluggish compared to more performance-oriented options.

Traction and durability

The outsole is equipped with Continental rubber, providing excellent grip on a variety of surfaces—wet or dry. Traction is reliable and secure. Durability is also a highlight: even after many miles, wear is minimal.

The Torsion System between the heel and forefoot adds a stable base and smoothens transitions. Despite the shoe’s flexibility, this system prevents instability and inspires confidence with every stride.

Fit and ergonomics

Fit is another strong point of the Ultraboost 5X. With no stiff or plastic components in the midfoot, your foot moves freely and naturally inside the shoe. The seamless interior enhances long-distance comfort by eliminating friction points that could cause irritation.

Additionally, the heel structure and inner padding provide soft yet effective support. This keeps your foot secure, which is appreciated during both training and everyday wear.

Weight and running feel

A standout improvement from past versions is the reduced weight. At just 275 grams in a men’s size 9 (EU 42), the Ultraboost 5X is impressively light for a max-cushion shoe. This weight reduction translates into greater agility and a smoother stride.

While not designed for racing, it allows for an easy pace on recovery or daily runs—and performs excellently during long walks or full days on your feet in the city.

Style, versatility, and build quality

Visually, the Ultraboost 5X maintains the sleek, modern aesthetic the series is known for. These shoes transition seamlessly from gym to street, and even fit into office or casual settings. Adidas has paid close attention to detail, and the quality is apparent both to the eye and touch.

Multiple colorways make them easy to pair with various outfits, and the premium design elevates their appeal beyond performance.

Conclusion

The Adidas Ultraboost 5X is ideal for those seeking comfort, cushioning, and versatility in one shoe. With its sock-like Primeknit upper, new Light BOOST midsole, and durable Continental outsole, it’s a well-rounded option for easy training runs, long walks, or stylish everyday wear.

While they may not be the fastest or most breathable shoes on the market, their balance of comfort, design, and build quality more than justifies the investment. A great choice for anyone who values foot comfort and daily versatility.
