86 / 100 based on 3 expert reviews

    So, upon trying on initially, it was cool walking around. You can literally feel it spin and then snapping back underneath. As far as running goes, when you step down into them, it's really nice because you can't really feel underneath.

    I just feel like the rest of the shoe needs to be tweaked a bit to accommodate a wider variety of foot shapes. While the cushion was a fun aspect of the shoe, something I haven’t felt before, I wouldn’t want to run in them again. Well, maybe I would, if they were wider.

  • The Asics GEL Quantum Infinity is the first ever shoe from Asics that features a visible full-length GEL technology.  It is also the most recent shoe that was engineered and tested at the Asics’ Institute of Sport Science in Kobe, Japan. Made within strict standards, the GEL Quantum Infinity is developed to provide a high standard level of cushioning and durability with their GEL-packed midsole from heel to toe.
  • The GEL Quantum Infinity has been constructed via 3D ‘Puff Print’ which allows the seamless one-piece upper.  With this comes the slim tongue design that makes the whole upper not only aesthetically pleasing but also very lightweight.
  • Deriving inspiration from water drops that smoothly transitions into water ripples can be seen reflected on the shoe’s outsole to the upper design.  Keeping up with the Japanese tone for the whole make of the shoe is the word Infinity written in the Japanese character, Katakana, and is showcased on both the tongue and heel to complete the entire essence of the design.

The GEL Quantum Infinity is a shoe that comes in standard sizing.  It fits true to size which means anyone can go with their usual size preference and be assured that it will fit comfortably.  The fit is snug, and flexible thanks to the shoe’s upper which Asics refer to as a “vacuum no-sew material execution.” The shoe’s width comes in medium D for men, and medium B for women.  The toe-box is also known to provide ample space for supporting toe splay whenever it is needed.

The Asics GEL Quantum Infinity features a rubber and GEL outsole that provides the shoe with quality cushioning and traction.  The GEL technology guarantees comfort and flexibility. The shoe also has ample grip and support that makes every run more enjoyable.

The outsole layout is in sync with the rest of the shoe’s theme by featuring a design inspired by water droplets and a rippling effect.  The Asics’ Infinity symbol written in calligraphy style can be seen atop the eye-catching outsole.

The main highlight for the Asics GEL Quantum Infinity is showcased in its midsole.  It features the first ever full-length midsole that is pioneering a new era for the Asics GEL running shoe franchise.  The GEL midsole is engineered from inert polymers to derive silicone. This technology provides cushioning function and durability.

The GEL Quantum Infinity uses the Asics REARFOOT and FOREFOOT GEL Technology Cushioning System which provides the uniform impact cushioning.  The technology works by absorbing impact on the heel every time the foot hits the ground. The layout of the mid-platform also gives the shoe the needed stability for road running.

The Asics GEL Quantum Infinity is also equipped with the ORTHOLITE insole and sockliner.  This guarantees the shoe’s responsive effect, reliable cushioning, and a high level of breathability.  The removable Ortholite sockliner also has good moisture wicking properties and ensures the long-lasting durability of the shoe by allowing a cool, dry and healthy environment within the shoe.

What makes the upper of the GEL Quantum Infinity stand out is that it boasts a seamless one-piece upper that is made possible via 3D puff printing.  Asics describes this as a “vacuum no-sew material execution.” The seamless construction provides breathability and a lightweight feel on the entire upper.  The materials used in the GEL Quantum Infinity’s upper are robust and does not lose its shape even with long-wearing.

The shoe’s upper features a lace-up closure, slim tongue design, and a padded collar that give the shoe not just an updated design but also a comfortable fit.  The refined heel detailing with a seamless finish in the forefoot also helps in preventing the probability of any irritation.
