Product Information

Full details

The ASICS Gel-Quantum 360 I is designed for adult athletes and casual wearers seeking a blend of heritage design and modern comfort. The key benefit of this model is its signature 360-degree GEL technology, which provides comprehensive impact absorption throughout the entire midsole, paired with updated FF BLAST PLUS cushioning for enhanced underfoot softness. One caveat for potential users is that the jacquard mesh construction and structured heel counter offer a more locked-in, stable fit that may feel more rigid compared to ultra-minimalist foam-only trainers.

FAQs

Are these shoes suitable for running?

Yes, they are designed for performance, though the 360-degree GEL provides a higher degree of stability and cushioning that is often preferred by those seeking extra shock absorption.

How do I determine my size?

This model follows standard adult UK sizing; if you are between sizes or prefer extra room for movement, some users prefer to go up by a half size.

Can I replace the insoles?

Yes, the sockliners are removable, allowing you to insert custom orthotics if required for additional arch support.

Are these unisex?

Yes, the Gel-Quantum 360 I is built on a versatile platform suitable for all genders, provided the correct sizing is selected.

What is the primary difference between this and older models?

While it retains the iconic look and 360-degree GEL foundation of the 2015 original, this version features updated FF BLAST PLUS foam for a more modern, comfortable underfoot experience.

Troubleshooting

Feeling of stiffness in the sole

The shoe features a structured support system; continue wearing them for short periods to allow the FF BLAST PLUS cushioning to conform to your foot strike.

Accumulation of dust in the mesh

Use a soft-bristled brush or a handheld vacuum on a low setting to gently lift debris from the jacquard knit pores.

Setup, Compatibility & Care

To ensure the longevity of your Gel-Quantum 360 I sneakers, it is recommended to keep them clean by removing surface dirt with a soft brush or a dry cloth. Avoid machine washing or using harsh chemical cleaners, as these can compromise the integrity of the GEL unit and the mesh fabric. If the interior becomes wet, remove the sockliner and air dry naturally away from direct heat sources like radiators. For optimal comfort, ensure the laces are tightened to your preference to leverage the benefits of the external heel counter without restricting circulation.
