Full details

The ASICS Novablast 5 is a high-performance trainer designed for adult runners who prioritize energy return and cushioned comfort during daily training sessions. Featuring a sophisticated white and grey aesthetic, this model balances a stable flat heel with a responsive ride to help you maintain momentum. While it offers excellent versatility for various distances, users should note that the high-stack design may feel less grounded than minimalist racing shoes.

FAQs

Are these shoes suitable for marathon training?

Yes, the Novablast 5 is designed with high-energy return cushioning, making it a popular choice for long-distance training.

How should I clean the white upper?

Use a gentle cloth with cool, soapy water. Avoid bleach or harsh chemicals which may yellow the fabric.

Can I replace the insoles?

Yes, the insoles are removable and compatible with most aftermarket orthotics or custom inserts.

Are they true to size?

Most runners find the ASICS sizing to be standard; however, if you wear thick performance socks, you may consider a half-size up.

Is this shoe intended for trail running?

No, this model is primarily engineered for road and track performance and lacks the aggressive tread needed for technical trails.

How often should I replace them?

Generally, running shoes should be replaced every 300 to 500 miles, depending on your running surface and intensity.

Troubleshooting

Feeling of slipping or heel lift

Re-lace the shoes using the final eyelet to create a runner's loop, which secures the heel more firmly.

Foam appears compressed after use

Allow at least 24 hours between runs for the midsole foam to fully decompress and recover its shape.

Pros and Cons

Pros

  • Superior cushioning for long-distance comfort
  • High-energy return midsole technology
  • Reliable and stable flat heel design
  • Versatile style suitable for non-athletic use

Cons

  • Higher stack height may lack road feel
  • Requires break-in time for optimal comfort
  • White colourways require frequent cleaning

Setup, Compatibility & Care

To ensure the longevity of your ASICS Novablast 5 trainers, use the lace-up system to achieve a snug but non-restrictive fit across the midfoot. For care, avoid machine washing or drying, as high heat can degrade the cushioning foam. Instead, remove the insole and hand-wash it separately with mild detergent and cold water. Clean the outer shell using a soft brush or damp cloth to remove dirt. Always air dry your shoes in a well-ventilated area away from direct sunlight to prevent material discoloration or structural warping.
