Good to know

Stylishness goes hand-in-hand with functionality when it comes to the Ultraboost Guard. This Adidas running shoe aims to become an accommodating choice for those who desire eye-catching, sneaker-like silhouettes from their trail shoes. The materials of the upper unit are all optimized for the trails, with close-weave fabrics working with a bevy of reinforcing layers to ensure sturdiness during the runs.

Underfoot cushioning is the responsibility of the tried-and-true Boost™ technology. It has a generous thickness to ensure consistent buttressing of the underfoot. It is also supported by a thermoplastic layer in the midfoot to maintain the structure and ease the strain on foot muscles.

The Adidas Ultraboost Guard is made to be true to size. Runners are welcome to utilize the sizes to which they are most accustomed, potentially getting an in-shoe feel that seems personalized. It would be helpful if this product is tested first or if reviews that cover the aspect of size are studied as these can determine the overall comfort and quality of the wearing experience.

The outsole unit of the Adidas Ultraboost Guard is made of Continental™ rubber. This car tire-grade compound is tasked with protecting the bottom part of the midsole from the abrasive nature of the outdoor paths. Its touted durability also works with its traction-ready nature to deliver confident grip and sureness of movement.

Stretchweb is an outsole tread-pattern that involves gripping nodes and flex grooves. The end-goals of this design are heightened traction over the uneven terrains and natural foot flexibility.

Boost™ is the technology that is used for the midsole unit of the Adidas Ultraboost Guard. This full-length accoutrement is meant to cushion the underside of the foot, ensuring that the impact shock generated by the landing phase won't be detrimental to the quality of the step. It also has a springy nature, which enables the foot to experience a responsive forefoot lift. Boost™ graces many of Adidas' offerings, including the much-loved Pureboost line.

The Torsion System is a thermoplastic layer that rests in the midfoot section. The job of this feature is to maintain the form of the primary cushioning unit, permitting it to stay as robust as it was initially. It also assists the muscles and tendons of the foot-pad, saving them from the strain that comes naturally when running.

The upper unit of the Adidas Ultraboost Guard is made of a close-weave version of the in-house Primeknit technology. The job of this design is to prevent trail debris from infiltrating the inner chamber of the shoe or tearing through the fabrics.

A one-piece opening allows the foot to experience a sock-like fit that is seamless and free of shifting parts.

Side-panels help the traditional lacing system to lock the foot in place.

Water-repellent printed overlays shield the forefoot section and the sides of the vamp from damage.
