Adidas Cosmic 2 SL Review Facts
Watch Video Review

Adidas unveiled the Cosmic 2 SL toward the end of 2017 and it has proven to be a successful model. There are a number of great features in this sneaker that appeal to the runner and every day Joe alike. The most notable feature of the Cosmic 2 SL is its style; this is a good-looking sneaker. The upper features a flexible mesh knit material that is on-point with today’s style while its silhouette is sleek and sophisticated. The non-marking Adiwear outsole provides just the right amount of grip and traction for a road running sneaker, but not too much so that it screams out that it is, indeed, a running sneaker. The cushioning provided by the shoe’s Cloudfoam insole is incredibly comfortable and supportive, while the removable Ortholite insole adds even more comfort. The upper will conform to almost any foot shape thanks to the included stretch of the mesh material and the heel counter will keep your foot from slipping out. All of these features combine to create an attractive sneaker at a price point that virtually anyone can afford. The Adidas Cosmic 2 SL really is a great all-around package for the neutral everyday runner or even for someone looking for a comfortable lifestyle sneaker.

Outsole
Outsole

Outsole

This lightweight running shoe features an outsole made from Adidas’ AdiWear rubber. This technological material is an extremely durable non-marking rubber designed to resist abrasion and provide excellent traction. It also possesses the ability to stretch and flex with the foot to allow for a great amount of natural movement throughout your run. Because it is non-marking, they are perfect to wear either indoors or out. The unilateral tread pattern is seen throughout the length of the outsole and is made up of dozens of rectangular different sized low profile lugs. There are also a good number of flex grooves placed throughout to add even more flexibility to the outsole of this sneaker.
Midsole
Midsole

Midsole

The Adidas Cosmic 2 SL features a Cloudfoam midsole which is an innovative material designed to deliver superior comfort and performance. Adidas engineered Cloudfoam to deliver cushioning and comfort even after hours of wear as well as to absorb shock. This shoe also features a removable Ortholite sockliner insert for added comfort and support. Ortholite is also a great weapon to fight against bacteria and odor that have a way of forming inside athletic sneakers. This insole can be removed and replaced with a customized orthotic insole if needed, but it is a great feature for anyone who does not have foot issues.
Upper
Upper

Upper

The nearly seamless upper of the Cosmic 2 SL is made up of a 2-tone knit material that provides both comfort and breathability. It has a small amount of stretch to it so it will mold and adapt to each individual’s foot. This flexible material will help keep your foot snug and secure without being too constricting. Because it is entirely a flexible mesh material, the upper lends itself to being extremely lightweight and breathable. At the heel, you will find a semi-flexible yet firm plastic heel counter with a dip in the middle. This heel counter is designed to lock your heel in place while allowing the Achilles to move freely. The heel also boasts a pull tab at the top. Unlike many sneakers with a loop at the heel, the Cosmic 2 SL has a tab that is more of an extension of the upper to allow for easy on and off. At the base of the lacing system, you will see a synthetic mesh overlay which reinforces the eyelets for added durability of the upper. Both the tongue and the heel cup feature additional padding for added comfort.

Currently, a popular shoe style is a knit upper and this sneaker fits that trend perfectly. Adidas’ well-known three stripes are tastefully emblazoned on both the lateral and medial sides of the upper, giving them a sleek look. These stripes are just a touch off in terms of color from the upper, making them a great outfit accessory if you wanted to wear them out with friends. Some of the colorways feature a shinier version of these stripes which is tasteful and attractive.
Durability
Durability

Durability

The flexible yet protective Adiwear rubber outsole of the Cosmic 2 SL provides great durability against abrasion and is designed for long-term wear. The upper consists primarily of stretch-knit mesh material and is made to move with you so that helps in the durability department since the material won’t be pushed to its limits if it were without flexibility. Thanks to the added synthetic overlay to support the eyelets, the lacing system will stay intact without ripping. These features make the sneaker relatively durable, even though they are lightweight and made mainly of mesh.
Protection
Protection

Protection

The Cosmic 2 SL will help protect you from ground debris thanks to the durable Adiwear rubber outsole. Although the sneakers do not boast an aggressive lug system, they are perfectly suitable to protect your feet during everyday wear, at the gym, or on a run. The mesh upper won’t protect you from severe underfoot and trail conditions however so they shouldn’t be worn trail running. If you happen to get caught in the rain, the mesh upper won’t keep your feet dry, but because these sneakers provide optimal airflow, your feet will at least dry out quickly.
Responsiveness

The EVA compound will absorb shock and spring back to its original shape and give you a little spring in your step.

The Ortholite insole will also help to fill in any negative space in the foot chamber and keep your foot supported.

Terrain

Adidas is a well-known brand name which, many times, comes with a larger price tag.

The Adiwear rubber outsole is a highly durable non-marking material that is designed to provide excellent traction indoors or out. The small rectangular unilateral lugs will help keep you sure-footed whether you are in wet or dry conditions.

Flexibility
Flexibility

Flexibility

These sneakers offer some excellent flexibility features starting with the outsole. The lightweight Adiwear rubber lends itself to a great amount of flexibility alone, but the flexibility of the outsole is increased with the help of the flex grooves that run the length of the shoe. A Cloudfoam midsole also adds to the sneaker’s flexibility because it is lightweight and responsive. Finally, the mesh upper is not only flexible alone thanks to the added stretch of the material, but because the upper is mostly seamless, it is not stiff at all. The culmination of all of these features combines to make a pretty flexible neutral running shoe.
Stability
Stability

Stability

The Cosmic SL 2 is not marketed as a “Stability” running shoe, it is more of a neutral running shoe. They are well-suited for anyone who has a neutral gait but can but used if you tend to overpronate as well. They do not offer a ton of out-of-the-ordinary arch support so if you have arch concerns, you may need to add your own orthotic insole. These sneakers are fairly supportive and will keep your heel and foot secure, but they are not highly stabilizing shoes.
Drop

Drop

These have a moderate drop of 10mm. This drop adds a little more support if you tend to be a heel striker but is good for any neutral runner.
