ASICS Sonicblast Trainers - Blue - UK 9

The ASICS Sonicblast trainers are designed primarily for speed training, tempo runs, and shorter to mid-distance races on asphalt surfaces. They focus on providing energy return and promoting fast paces.

They utilize a combination of FF TURBO SQUARED and FF BLAST MAX cushioning, designed for high energy return and a responsive feel.

The ASTROPLATE, a TPU plate, is integrated to optimize every stride, helping to propel you forward and create a faster, more efficient toe-off.

While they offer advanced cushioning, their design is optimized for speed. For marathon distances, especially if prioritizing maximum comfort over extended mileage, other ASICS models might be more suitable.

The heel-to-toe drop is 8mm.

No, the ASICS Sonicblast trainers are specifically designed for asphalt and hard, paved surfaces. They are not recommended for trail running due to differences in grip, durability, and support required for uneven terrain.

Clean with a soft brush or damp cloth. Avoid machine washing or harsh chemicals to preserve the shoe's integrity and performance features.

This is normal for speed-focused shoes. Perform a few short runs on familiar terrain to break them in. Ensure you are using them for their intended purpose (speed training).

The Sonicblast is optimized for speed, not long-distance comfort. Consider a different shoe model for extended mileage or recovery runs. Ensure you are running on appropriate surfaces (asphalt).

The internal plate is designed for propulsion. If it causes discomfort, the shoe's geometry or stiffness may not suit your biomechanics. Ensure the shoe size is correct and consider if this type of shoe is appropriate for your running style.

While designed for asphalt, grip on extremely wet surfaces can vary. Ensure the outsole is clean. For wet conditions, consider shoes with enhanced wet-weather traction if this becomes a persistent issue.
