Outsole
Outsole

Outsole

The Continental Rubber outsole provides incredible traction in all weather conditions, while the Stretchweb rubber outsole works to maximize the distinctive properties of the Boost from the time your foot touches the ground to the time it pushes off. It is lightweight and elastic - a single perforated sheet of soft rubber -  allowing it to adapt to the ground for stability.
Midsole
Midsole

Midsole

The full-length Boost midsole is made with expanded polyurethane foam, offering optimal and resilient cushioning throughout your run. This foam, made by BASF-adidas, works in conjunction with the Stretchweb outsole to utilize the energy harnessed in each step. This, in turn, allows you to run further with less fatigue. 
Upper

Upper

Primeknit stretch mesh is combined with closed-stretch mesh and a plastic mid-foot cage to form the upper portion of the shoe. The Adidas Ultra Boost also offers Sockfit for snugness and support. 
Weight
Weight

Weight

The high volume of the Boost as well as the use of plastic increases the weight of this running shoe. However, Adidas has tried to counter this by using a single latticed sheet to clothe the bottom of the shoe. The exposed “windows” help to reduce weight and increase speed. A U.S.  size 7 weighs 9 ounces; a size 11 weighs 11.74 ounces. 
Breathability
Breathability

Breathability

For 2016, Adidas updated the Ultra Boost with improvements for, not only support and flexibility, but also for breathability. The Primeknit stretch mesh that forms the upper portion of the shoe, allows maximum airflow to reduce perspiration. 
Comfort
Comfort

Comfort

The collar and the upper part of the tongue are cushioned with foam, allowing for extra comfort. In fact, the whole upper lining of the mid-foot is cushioned to help reduce lacing pressure. The narrow fit of the shoe may make this shoe uncomfortable for those with a wider foot. The only width available is the single, D-standard. It is not recommended to wear this shoe without socks due to the internal toe puff the may catch on the small toe. With socks, this does not appear to be a problem.

Style

Some have complained of the limited variety of colors with the Ultra Boost. However, this year, Adidas has introduced several new styles, including the heather grey and white Ultra Boost with Continental Tire rubber on the outsole. There are also plans to roll out the Triple Black Ultra Boost this fall. In addition to being considered one of the best running shoes, this shoe is also considered stylish enough to wear with everyday clothing. 
Durability
Durability

Durability

While the upper and midsole portions of the shoe appear quite durable, the sole seems to wear down at a higher-than-average rate. This is likely due to the outsole being only a super-thin single perforated sheet of rubber to act as a barrier between Boost and pavement. When the thread on the sole tears or the nubs underneath the sole wear down, the shoe loses the traction that it is known for. Adidas reports partnering with Continental Tire in order to fit the Ultra Boost with an improved outsole for longer durability. 
Protection

Protection

Many reports suggest the Ultra Boost Triple Whites stain easily. Runners often report using Crep Protect Stain Resistant Barrier Spray to repel liquids and prevents stains on this shoe. 
Responsiveness

Responsiveness

Adidas Ultra Boost’s energy-returning properties are designed to charge each step with speed. With this being said, for those runner seeking comfortability and excellent cushioning, this shoe is often referred to as a great training shoe for slower miles. 
Support
Support

Support

The TORSION®SYSTEM  in conjunction with Sockfit helps to support and protect the ankle. The TORSION®SYSTEM is designed for mid-foot integrity. And, due to Sockfit, there is no need to over-tighten. In addition, the external heel counter keeps the heel in place, preventing movement inside your shoe. While this shoe is designed mostly for the neutral runner, the Ultra Boost’s arch support is noted to allow slight to moderate over-pronators to experience an enjoyable run.

The Ultra Boost is designed primarily for the pavement. However, because of the incredible traction provided by the Continental™Rubber outsole, this shoe is also desirable for trail.
