Since its initial release in February 2015, the Ultraboost series has evolved through seven iterations. The Ultraboost 21 from this year has undergone significant design changes, including a more assertive appearance, more personality, more BOOST, and an entirely new BOOST part fixation system.

The midsole now features a considerably thicker BOOST, notably in the heel, which is the first immediately noticeable significant alteration. When compared to the Ultraboost 20 from last year that I have in my hand, this is readily apparent. According to Adidas, the new edition has 6% more BOOST than the previous one, which contributes to the sole’s improved smoothness, bounce, and elasticity.
Additionally, the heel of the BOOST sole is significantly more curled than it was in earlier editions. The ground contact area of Ultraboost 21 is reduced as a result, resulting in more forward push when running.

Review of Adidas Ultraboost 21 shoes: Continenta outsole is incredibly durable

he sole of these sneakers is one of the first things that stands out to me. The Ultraboost 21’s outsole is made by Continental, the renowned German tire business, and is available in a variety of colors, including black, blue, gray, pink, and white. It is also no longer covered. Rubber has different characteristics depending on the hue. As an illustration, black rubber is tougher than gray rubber, which is harder than pink rubber, which is harder than milky white rubber. The shoe has increased traction and power thanks to this outsole design. In addition, the heel has a sharp bevel to safeguard the BOOST sole.

Review of the Primeblue technology-enhanced Adidas Ultraboost 21 footwear

The fabric used to make Ultraboost 21 is Primeblue technology, a high-performance textile derived from recycled ocean plastic waste and Parley Ocean Plastic yarn. Primeblue yarn makes up 75% of the woven fabric, which makes up 50% of the shoe’s body. Use virgin polyester sparingly. The fabric is thick, soft, and extremely smooth; it gives the impression of caressing your feet properly without irritating them. To prevent the foot from moving during movement, the toe box is lined with a firm layer of padding.

Cons of the Adidas Ultraboost 21 shoes

The shoe weighs 340g, which is a significant amount because the boost portion has been increased by 6% and is combined with a strong woven fabric. As a result, the shoes are appropriate for daily jogging, walking, and short-distance running as well as for the lifestyle of leaving the house for work.
Since the toe box’s woven fabric is composed of Parley Ocean Plastic, frequent bumping will cause it to easily ruffle. This, however, is unimportant if you are a runner who cherishes the outdoors and cares about the environment.


The Ultraboost range of shoes has been greatly improved with the release of the Adidas Ultraboost 21. With those who enjoy sports shoes (everyday casual shoes), it scores well thanks to its stylish appearance and personality. Thanks to the improved LEP system, the shoes offer a completely new experience. Ultraboost 21 is appropriate for gradual, extended runs between 8 and 15 kilometers. Excellent energy recovery shoes are perfect for daily exercise and aid in maintaining your pace. The Ultraboost 21 can be worn for a run even though it resembles a Hyperbeast shoe.
