ASICS Sonicblast Trainers - Blue - UK 10

The ASICS Sonicblast trainer is best suited for adult male runners who focus on speed training, interval workouts, and tempo runs on asphalt surfaces, and who have a neutral foot strike.

The ASTROPLATE, a TPU plate within the midsole, is designed to enhance propulsion and optimize energy return, helping runners achieve faster paces more efficiently.

The Sonicblast features FF TURBO SQUARED + FF BLAST MAX cushioning, which is engineered for high responsiveness and energy return, making it firmer and more propulsive than traditional, softer cushioning found in daily trainers.

While they offer energy return, they are primarily designed for speed training. For long-distance marathon running, especially if comfort and maximum cushioning are prioritized over pure speed, other ASICS models might be more suitable.

The ASICS Sonicblast trainer weighs approximately 256 grams (for a men's UK size 9), contributing to a lightweight feel for faster running.

Clean them using a damp cloth with mild soap and water. Avoid machine washing or using harsh detergents. Always allow them to air dry naturally at room temperature.

The ASICS Sonicblast trainer has a heel-to-toe drop of 8mm.

Ensure you are wearing appropriate running socks. Try adjusting the lacing pattern. If discomfort persists, consider if this is the correct size and width for your foot. Consult the ASICS sizing guide if unsure.

Cushioning foams can degrade with extensive use. Ensure you are not exceeding the intended lifespan of the shoe for speed training. Proper care and avoiding excessive heat can help maintain performance.

The outsole is optimized for dry asphalt. For wet conditions, exercise caution as grip may be reduced. Consider alternative shoes designed for wet weather running if this is a frequent concern.

The ASTROPLATE is designed to enhance performance but may require a break-in period. Try wearing the shoes for shorter runs initially to allow your feet to adapt. Ensure the shoe is correctly sized.
