Efficient performance in both wet and dry conditions

The Continental rubber outsole aims to provide traction in both wet and dry conditions. Following the concept of automotive technology, the outsole is like a tire rubber that possesses more durability against natural wear-and-tear.

With the Stretchweb rubber on the outermost part, the impact of the foot strike is reduced, thus lowering damage and increasing performance. It also aims to handle various road surfaces that a runner may come across.

Prevent improper arch flexion

In the midfoot area lies the Torsion system that functions as a platform to help prevent improper arch flexion, therefore resulting in a more stable ride.

The purpose of the Torsion system is to provide protection and control during strides and movements for a smooth heel-to-toe transition.

Ultraboost Laceless provides responsive cushioning

The laceless version of the Ultraboost makes use of the Boost technology, which Adidas touts as the most responsive cushioning unit in the market. It works on the notion that energy given will also result in energy received.

The Boost cushioning system is made from the amalgamation of TPU capsules. This design enables the midsole to absorb energy and impact differently than standard EVA foams. The responsiveness of boost is comparable to a bouncing effect.

A sock liner is included to provide additional cushioning to the foot; it can be removed to allow the use of custom inserts.

Adidas Laceless delivers exact level of flexibility and support

Because the shoe does not have laces, the Primeknit upper works double-duty in providing comfort and support to the foot.

Primeknit uses the concept of digital knitting to produce an exact level of flexibility and support, allowing the upper to wrap the foot seamlessly without restraining it.

There are several rows of ridges that are stiff and textured on the midfoot area where the shoelaces would be if there were any. The ridges act similarly to a rib cage: they protect the foot.

Adidas Ultraboost Laceless offers natural fit

Instead of a tongue, there is a single-piece pull tab and heel collar that allows the foot to get the shoe on and off with minimal effort. It is made from a fabric material that is slightly padded to prevent abrasions and injuries.

The FITCOUNTER heel counter secures the foot to maintain a natural fit without causing too much pressure to specific areas like the Achilles.
