Outsole
Outsole

Outsole

The outsole of the Adidas X Reigning Champ Ultraboost is certainly something for the company to be proud of. Adidas has partnered with the Continental tire company to create a super-dependable outsole. The continental rubber gives you outstanding traction in almost any terrain and responds well with each step. This outsole is considered to be an 'all-terrain' or ATR outsole and is up to the challenge when it comes to protection and response whether on the road or the trail. Adidas calls the pattern of the outsole a “stretchweb” design and delivers natural flexibility for an energized ride. All in the all, this sneaker’s outsole is pretty amazing.
Midsole
Midsole

Midsole

Ultraboost technology makes up this sneaker’s midsole. BASF, the world’s leading chemical company, partners with Adidas to make this innovative cushioning material that is designed to respond to each step. The more energy that is put into this midsole, the more it will give out. The thermoplastic polyurethane, or TPU, material compresses under pressure for ultimate shock absorption and instantly bounces back to its original shape, delivering an awesome running experience.
Upper
Upper

Upper

Matching with the current knit sneaker trend, the Adidas X Reigning Champ Ultraboost enters today’s marketplace with a similar design. This sneaker’s ‘Primeknit’ upper wraps the foot with adaptive support and lightweight comfort. The engineered knit provides an excellent amount of breathability in areas of the shoe where you need it most. One obvious feature of the upper is its ankle height which provides extra warmth and protection while its integrated cage offers adaptable support. This shoe also boasts a molded heel counter which provides a natural fit and delivers optimal movement of the Achilles. Another unique feature of the sneaker’s upper is something you can’t necessarily see: a water-repellent coating that will give you an advantage in hazardous weather. The upper also features reinforced eyelets which keep the laces in place and helps the sneaker stay snug on your foot. The company also offers the finishing touch of ‘RC’ emblazoned on the left tongue of the sneaker, standing for “reigning champ”.

Durability

Durability

The outsole of this sneaker is extremely durable due to its stretchweb design. The durable rubber of its outsole gives it the ability to withstand a great number of runs in any weather. The molded heel counter helps this sneaker keep its shape as well, meaning that the lifetime of this shoe will be longer than if it didn’t have the molded heel due to its completely knit upper. With that said, because of its all-knit upper, this shoe may be susceptible to wear if exposed to the elements on a regular basis. Although the outsole is made pretty tough, its upper lacks in stiff, durable material, making it a little less durable than some. With that said, the sneaker is equipped with a water-repellent coating, which offsets its lack of durable materials slightly.
