ASICS Magic Speed 4

The ASICS Magic Speed 4 features an engineered mesh upper that provides a snug fit and enhances breathability. This design ensures that the shoe remains lightweight while offering adequate support during runs. The mesh material allows for excellent airflow, making it suitable for running in various weather conditions. The upper's seamless construction helps reduce irritation and provides a comfortable fit, although some runners may find it a bit narrow. The gusseted tongue (meaning the tongue is attached to the upper most of the way to the opening of the boot under the laces) helps keep it in place, adding to the overall comfort and fit.

The midsole of the ASICS Magic Speed 4 is a standout feature, incorporating FF Turbo foam for lightweight and responsive cushioning. This foam is designed to provide a bouncy and energetic feel, enhancing the shoe's performance during speed training and racing. The midsole also includes a full-length carbon fiber plate, which aids in propulsion and stability, making it ideal for runners who prioritize speed. The combination of these technologies results in a dynamic ride, although some may find the energy return not as high as expected.

The outsole of the ASICS Magic Speed 4 is equipped with ASICSGRIP rubber, known for its excellent traction and durability. This compound ensures a secure grip on various surfaces, making it suitable for road running. The outsole's design includes a visible carbon plate in the midfoot, which contributes to the shoe's propulsion capabilities. The thickness of the outsole is slightly above average, providing additional durability without compromising flexibility. This makes the Magic Speed 4 a reliable choice for runners who need a shoe that can withstand regular use.

The ASICS Magic Speed 4 offers a snug fit, particularly in the midfoot and forefoot areas. The toe box is designed to be narrow, which may not accommodate all foot shapes comfortably. Runners with wider feet might find the fit too tight, while those with narrower feet will appreciate the secure lockdown. The shoe's overall fit is similar to that of racing shoes, providing a close-to-foot feel that enhances performance during speed workouts. It's important for potential buyers to consider their foot shape and size when choosing this model.

Comfort in the ASICS Magic Speed 4 is achieved through its well-cushioned midsole and supportive upper. The FF Turbo foam provides a soft yet responsive feel, making it comfortable for longer runs. However, the shoe's narrow fit might not suit everyone, potentially causing discomfort for those with wider feet. The tongue is thinly padded, which aligns with the shoe's lightweight design but may not offer enough protection for some runners. Overall, the Magic Speed 4 balances comfort with performance, making it a good option for those who prioritize speed.

The ASICS Magic Speed 4 features substantial cushioning, particularly in the heel area, with a stack height of 42 mm. This provides excellent shock absorption, making it suitable for longer runs and heavier runners. The forefoot cushioning is also significant, contributing to a smooth and comfortable ride. The FF Turbo foam used in the midsole enhances the shoe's cushioning properties, offering a soft yet responsive feel. While the cushioning is impressive, some runners may find it adds to the shoe's weight, which could affect performance for those seeking a lighter option.

Breathability is a strong point for the ASICS Magic Speed 4, thanks to its engineered mesh upper. This material allows for excellent airflow, keeping the foot cool and dry during runs. The asymmetrical design of the upper further enhances ventilation, making it suitable for running in warm conditions. The shoe's breathability is complemented by its lightweight construction, ensuring that runners remain comfortable even during intense workouts. This makes the Magic Speed 4 a great choice for those who prioritize a well-ventilated shoe.

Stability is one area where the ASICS Magic Speed 4 may not meet all runners' needs. While the shoe includes a carbon fiber plate for added support, its overall stability is limited, particularly for those who require more structured support. The narrow fit and lightweight design contribute to this, making it less suitable for runners with stability concerns. However, the shoe's stability is adequate for those with a neutral footstrike and good running technique. Runners seeking more stability might need to consider other options.

Durability is a highlight of the ASICS Magic Speed 4, with its ASICSGRIP rubber outsole providing excellent wear resistance. The shoe's construction is designed to withstand regular use, making it a reliable choice for runners who train frequently. The upper's engineered mesh is also durable, maintaining its shape and support over time. While the shoe's lightweight design might suggest otherwise, the Magic Speed 4 is built to last, offering good value for those looking for a long-lasting running shoe.

The ASICS Magic Speed 4 offers exceptional grip, thanks to its ASICSGRIP rubber outsole. This compound provides a secure hold on various surfaces, making it ideal for road running. The outsole's design ensures that runners can maintain traction even in wet conditions, enhancing safety and performance. The shoe's grip is one of its standout features, making it a reliable choice for those who need a shoe that can handle different terrains with confidence.

Flexibility in the ASICS Magic Speed 4 is moderated by the inclusion of a carbon fiber plate. While this plate provides propulsion and support, it also limits the shoe's flexibility to some extent. However, the shoe's overall design allows for a natural range of motion, particularly for midfoot and forefoot strikers. The flexibility is sufficient for most runners, although those seeking a more flexible shoe might need to explore other options. The Magic Speed 4 strikes a balance between flexibility and support, making it suitable for speed-focused workouts.

The ASICS Magic Speed 4 is equipped with a carbon fiber plate and FF Turbo foam, providing enhanced propulsion and energy return, making it ideal for racing.

While the ASICS Magic Speed 4 offers substantial cushioning, its narrow fit and limited stability may not be ideal for all runners during long-distance runs.

The engineered mesh upper of the ASICS Magic Speed 4 provides excellent breathability, making it suitable for running in various weather conditions.
