The consensus on the adidas SL20

The Lightstrike foam in the midsole offers a firm yet responsive cushioning, which is ideal for fast-paced runs. The engineered mesh upper ensures breathability, although some runners may find it too rough for sockless running. The Continental rubber outsole provides excellent grip, even on wet surfaces. However, the thin tongue and lack of support strips in the upper may require some adjustment for a secure fit. Overall, the SL20 is a solid option for runners looking for a lightweight and breathable shoe for fast runs. Its lightweight and breathable design makes it a top choice for speed training and racing.

Comparable Shoes


The Nike Zoom Fly 3 is a good alternative for runners looking for a lightweight and responsive shoe. It features a carbon plate for a quicker toe-off, making it ideal for racing. However, it is more expensive than the SL20 and offers a softer upper, which may be more comfortable for sockless running.

The adidas Adizero Pro is another option for runners seeking a lightweight and performance-oriented shoe. It features Lightstrike foam combined with Boost and a carbon plate, providing a softer and more responsive ride. The Adizero Pro is more expensive but offers additional benefits such as a softer upper and quicker toe-off.



The Nike Pegasus Turbo is a lightweight shoe that competes with the SL20. It offers more cushioning, making it suitable for longer runs. However, it is also more expensive and may not provide the same level of breathability as the SL20.

In Depth


Upper

The upper of the adidas SL20 is made from engineered mesh, which ensures excellent breathability and a snug fit. This material allows for continuous airflow, keeping the foot cool during runs. However, the upper can feel rough, making it uncomfortable for sockless running. The traditional lace closure offers a personalized fit, but the thin tongue may require frequent adjustments to achieve the right balance of security and comfort.

Midsole

The midsole of the adidas SL20 features Lightstrike foam, which provides lightweight and firm cushioning. This material is designed to offer a responsive ride, making it ideal for speed training and racing. The midfoot torsion plate (a supportive structure in the midsole) adds a touch of stability without making the shoe feel stiff. The 10 mm heel-to-toe drop (the difference in height between the heel and the forefoot) is standard for performance-oriented running shoes, offering a balanced feel for various running styles.

Outsole

The outsole of the adidas SL20 is made from Continental rubber, known for its durability and excellent grip. This material ensures superior traction on various surfaces, including wet pavement. The outsole design allows for quick turns and stable footing, making it suitable for fast-paced runs. The added rubber in the forefoot enhances grip, providing confidence during speed workouts.

Size/fit

The adidas SL20 offers a narrow fit, particularly in the toe box, which may not be suitable for runners with wider feet. The length is true-to-size, but some runners may find it slightly long. The traditional lace closure allows for a personalized fit, but the thin tongue may require frequent adjustments to achieve the right balance of security and comfort. Overall, the fit is snug and supportive, ideal for fast-paced runs.

Comfort

The adidas SL20 provides a comfortable ride, especially for fast-paced runs. The Lightstrike foam in the midsole offers firm yet responsive cushioning, while the engineered mesh upper ensures breathability. However, the rough texture of the upper may require runners to wear socks for added comfort. The thin tongue and narrow fit may also require some adjustments to achieve the right balance of security and comfort.

Cushioning

The Lightstrike foam in the midsole of the adidas SL20 provides lightweight and firm cushioning. This material is designed to offer a responsive ride, making it ideal for speed training and racing. The cushioning is not as soft as some other foams, but it provides a good balance of comfort and responsiveness. The thicker medial heel helps guard against early pronation (excessive inward rolling of the foot), adding a touch of stability to the shoe.

Breathability

The engineered mesh upper of the adidas SL20 ensures excellent breathability, making it a great choice for hot summer days. The material allows for continuous airflow, keeping the foot cool during runs. However, the rough texture of the upper may require runners to wear socks for added comfort. Overall, the breathability of the SL20 is one of its standout features, making it suitable for warm weather running.

Stability

The adidas SL20 offers a touch of stability thanks to its midfoot torsion plate and thicker medial heel. The torsion plate provides some resistance to unwanted motion, while the thicker medial heel helps guard against early pronation. However, the shoe is primarily designed for neutral runners and may not provide enough support for those with significant stability needs. The overall design focuses on lightweight and responsive performance.

Durability

The adidas SL20 is built to last, with its durable Continental rubber outsole and resilient Lightstrike foam midsole. The outsole provides excellent grip and shows minimal wear even after extended use. The midsole maintains its cushioning and responsiveness over time, making the SL20 a reliable choice for high-mileage runners. The engineered mesh upper is also durable, although its rough texture may require runners to wear socks for added comfort.

Grip

The Continental rubber outsole of the adidas SL20 offers excellent grip on various surfaces, including wet pavement. This material ensures superior traction, making it suitable for fast-paced runs and quick turns. The added rubber in the forefoot enhances grip, providing confidence during speed workouts. Overall, the grip of the SL20 is one of its standout features, making it a reliable choice for runners who need stable footing.

Flex

The adidas SL20 offers a good balance of flexibility and support, thanks to its engineered mesh upper and midfoot torsion plate. The upper provides a snug fit while allowing for natural foot movement, and the torsion plate adds a touch of stability without making the shoe feel stiff. The overall design allows for a responsive and flexible ride, making it suitable for speed training and racing.
