Adidas Adizero Boston Boost 6 Review Facts

The Adidas Adizero Boston Boost 6 is a lightweight trainer with just the right amount of cushioning for runners who like the feel of the open road beneath their feet. An improved upper (mesh for men, a fancier knit for the ladies) offers excellent breathability and also moves with the runner’s foot for added flexibility. This is a shoe designed to go fast and a casual run with friends could quickly turn competitive as the need for speed kicks in. The shoe has a good overall fit with the only real complaint being a tongue that can scrunch up if not pulled up tight. Despite this flaw, the shoe gets high marks for its comfort and great traction. Consider this neutral shoe for your next race or fast tempo run.

Outsole
Outsole

Outsole

The outsole of this shoe is made from two types of rubber. The heel area is comprised of Adidas’ AdiWear rubber which is a durable, high quality material. The forefoot area is made from Continental rubber, the same company that makes Continental tires. Both types of rubber are very lightweight and provide excellent traction. The use of two different kinds of rubber make the heel more durable and aggressive and the forefoot more springy and energized. For the runner, this translates to a smooth landing and a powerful push-off. This outsole is also good on slippery and wet surfaces. Wearers praised the outsole for its grip and ability to take on the miles with minimal treadwear.
Midsole
Midsole

Midsole

The midsole of this shoe contains the brand’s renowned Boost technology. Boost foam midsoles are comprised of thermoplastic polyurethane (TPU) pellets that are bonded together to create the midsole platform. These pellets bounce back quickly when compressed. They are also temperature resistant which means the shoe does not become stiffer in the cold or over flexible on hot days. Boost foam also provides good shock absorption and cushioning. Many distance runners prefer this unique foam over standard EVA foam found in most running shoes. A thin, removable, sockliner adds a bit more cushioning to the shoe.

Located in the midfoot area of the midsole is a Torsion System which is a thermoplastic protective plate. This plate allows the forefoot and midfoot to move independently which lessens the strain on the center of the foot. This component also provides arch support and helps with the runner’s stride. Runners prone to plantar fasciitis said the Torsion System helped them continue to run with minimal pain in the arch area.
Upper
Upper

Upper

The upper of the shoe differs depending on if the shoe is designed for men or women. The men’s version offers an open, net-like mesh material. The women’s model features a more knitted fabric. Both uppers offer excellent breathability and are soft and comfortable against the skin. The materials have some stretch which adapts to the foot’s movements. An inner Coolever mesh lining has good moisture-wicking properties which keeps the foot dry and cool, even after long-distance runs. Overlays stitched to the upper work in conjunction with the lacing system to support the foot and keep it in place. A heel counter on the back of the shoe keeps the heel aligned with the rest of the foot.
Weight
Weight

Weight

Weighing in at 8.8 oz for men (size nine) and 7.5 oz for women (size seven), the Boston Boost 6 is a fairly lightweight running shoe. The use of lightweight rubber in the midsole and outsole helps keep this highly cushioned shoe from weighing the runner down.
Breathability
Breathability

Breathability

The upper of this shoe offers great breathability. The material of both the men’s and women’s models is quick-drying if it does get wet and allows good airflow into the shoe. The overlays on this shoe are small, the three Adidas stripes, and do not interfere with airflow in any way. A wide toe box helps to ensure fresh air movement around the toes. Runners had no complaints about the breathability of the shoe, even after marathon distance runs.
Comfort
Comfort

Comfort

The Boston Boost 6 is a very comfortable shoe. The midsole is not overly cushioned, but the Boost rubber material provides a very cushioned ride. Most of the cushioning is in the heel area which means soft landings and good forefoot drip. Because there is less cushioning in the front of the shoe, runners will be able to feel the road beneath their toes. Some runners enjoyed this feeling and described is as the road being able to pull them forward. Both heel and forefoot strikers will benefit from the shock absorption properties of the midsole. The excellent moisture-wicking tendencies of the shoe help keep the foot cool and dry and prevent blisters and chafing. When lacing up the shoes before a run, be sure the tongue is centered and tight. Some runners had a problem with the tongue folding over which caused a pressure point on the top of the foot. The overlays and laces work together to customize the fit of the shoe. A few runners though this version was more narrow than the Boost Boston 5.
Style
Style

Style

There is no mistaking an Adidas shoe. The “three stripe” logo has been featured on the company’s athletic apparel since 1952. Their running shoes tend to come in standard dark colors with few contrasting highlights. Runners who prefer subdued shoes will enjoy the neutral color options. The midsole and outsole are also rather plain with the emphasis being on function rather than fashion. If you enjoy bright colored shoes with space-age looking midsoles, these shoes are probably not for you.
Durability
Durability

Durability

This is a durable shoe. Wearers can expect to get 400 to 500 miles out of this shoe. The Continental outsole incorporates some of the same high quality rubber material properties that are used on car and truck tires. This rubber is resilient enough to withstand not only wet and dry pavement, but also wide temperature fluctuations. This means the shoe will give a consistent performance no matter how hot or how cold the pavement. This technology also helps the shoe maintain its integrity longer. When rubber gets hot, it tends to soften and can break down quicker. Cold rubber can stiffen and also lose its durability. In addition, the shoe incorporates AdiWear foam rubber which is abrasion-resistant and durable. The upper material of the shoe is also quite durable despite its thinness.
Protection
Protection

Protection

This shoe is designed to be a road shoe. The only real protection comes from the outsole and midsole which are meant to cushion the runner’s foot from the road. The mesh upper works well to hold the foot securely in the shoe but is defenseless against snags and trail hazards. There is no toe guard and the overlays are minimal. A small flap of the outsole curls over the toe, but is designed for unexpected toe stubs. As a road shoe, this shoe functions well and sacrifices some protective features found in other shoes for its light weight.
Responsiveness
Responsiveness

Responsiveness

The Boston Boost 6 is a highly responsive shoe. A few wearers said it was a bit too bouncy for their liking. Adidas claims the Boost technology generates more energy than a standard EVA midsole platform. In addition to its responsiveness, the midsole also provides cushioning for the shoe. The majority of the cushioning is in the heel which accounts for the bouncy feeling. Despite the cushioning, the forefoot area still has good ground feel which allows for fast push-offs. Most runners like the fast feel of the shoe and had a hard time running slow once they got going.
Support
Support

Support

This shoe offers solid support through the design of the midsole and upper. The upper has an improved construction from the previous version which wraps around the foot for a comfortable, but tight fit. The upper material has some stretch which provides more stability without compromising flexibility. The midsole has a special system called a Torsion System. This system features a thermoplastic arch support which lets the forefoot move independently from the rearfoot. This feature prevents excessive strain on the arch and and allows the midfoot to adjust to hitting the ground. The result is a very smooth ride for the runner. The aggressive outsole also ensures a powerful and confident run.
Terrain
Terrain

Terrain

This shoe will perform well on most solid terrain, but the upper lacks the protection for rocky or heavily wooded trails. The Continental outsole provides excellent traction and durability for road running and the AdiWear rubber in the forefoot area offers just enough ground feel for most runners. The shoe performs well over both dry and wet surfaces, and in hot and cold temperatures.
Price
Price

Price

The Boston Boost 6 retails for $120. Online shoppers should be able to find the shoe for much less than this price. Even at the retail price, the shoe is competitively priced and will give the runner many miles of wear. The shoe fits true to size for most wearers so buying online should not be a problem. Look for stores that offer free returns.
Traction
Traction

Traction

This shoe has excellent traction on most hard surfaces. The Continental rubber on the outsole delivers better than average grip which allows the shoe to handle a variety of road conditions, from hot and dry to wet and slippery. Runners liked the way the heel and forefoot had a different feel which allowed for a smooth and powerful heel-to-toe transition.
Flexibility
Flexibility

Flexibility

Despite the moderately cushioned midsole, this is a fairly flexible shoe. The flexibility comes from the design of the outsole which has spaces between the tread lugs which act like grooves in the forefoot area. The midsole cushioning is also soft enough to flex with each step, offering a responsive feel for the entire run. The mesh material of the upper helps create a very flexible shoe that also retains its structure. Runners appreciated the stiffness in the heel area and flexibility in the forefoot that allowed for a natural feeling without being overly stiff.
Stability
Stability

Stability

This shoe has several stability features to correct any overpronation (inward roll) foot motions. The Torsion System allows the foot to move naturally and the midfoot cushioning carries the arch of the foot to ensure a stable ride. The midsole is not overly thick (19 mm in the forefoot) which makes the runner low to the ground compared to other cushioned running shoes. A moderate heel-to-toe drop also contributes to the stability of the shoe. The forefoot area of the shoe is fairly wide and stable for safe landings and push-offs.
Drop
Drop

Drop

With a stack height of 29mm in the heel and 19mm in the forefoot, the Boston Boost 6 has a resulting drop of 10mm. A 10mm heel-to-toe drop promotes a cushioned heel strike that lowers the chance of injury to the runner’s foot and knee. Most wearers described the shoe as very bouncy and responsive and the high heel-to-toe drop did not interfere with their run in any way. The Boost foam allows the midsole to remain fairly thin, but highly cushioned.
