    Don't get me wrong, I really like these shows, but they're more of a second pair of CrossFit shoes.

  • 90 / 100 | The Morning Drive With DamianJay | | Level 3 expert

    I would say that they're a lot more comfortable than the regular Nanos and i think, llike I sad, it's because of that bladder for you to pump it, so you have a lot more room in there.

  • 95 / 100 | Football Fashion | Level 1 expert

    Visually stunning, customizable, sturdy and extremely functional, the Reebok Pump ZPump Fusion is one of the standout training shoes of 2015.

  • 92 / 100 | All the Gear No Idea | Level 1 expert

    I quite liked putting a few extra pumps into the shoe when I was doing some heavy Oly lifting, this gave me a really sturdy base and snug fit that gave me great confidence when hitting 1 rep max lifts.

  • 85 / 100 | Nathan Phillips CT | | Level 1 expert

    So if you're someone like me, someone who doesn't spend too much of the time lifting and when they do lift won't be focusing on lifting predominantly heavy and has more endurance-based workouts then the Pump Fusions are a really good shoe for you.

    I recommend them. Other than that, they feel good and they're light.

- The Nano Pump Fusion was created with rigorous CrossFit WODs in mind. Its design pulls cues from the Reebok Nano series, blending it with the brand’s proprietary Pump technology. The Pump features a small inflation device that pumps air into a distinct bladder in the ankle area for a customized fit.

- The foot is wrapped in the Kevlar-infused fusion fit sleeve, which prevents chafing inside the shoe and provides abrasion-resistant coverage on the outside.

- A low-profile platform with a 5-mm drop provides a more grounded and stable foot disposition during lateral moves and weightlifting.

- The carbon rubber RopePro compound in the midsection delivers grip and protection during rope climbing.

The Reebok CrossFit Nano Pump Fusion can be found in both men’s and women’s versions. Both are offered in full and half sizes. The product follows standard training shoe measurements regarding length. The widths are D – Medium for men and in B – Medium for women.

The use of the Pump Air Cage in the helps athletes in achieving the optimum fit. By pressing the “pump” button, a wearer can regulate the amount of air in an inflatable chamber inside the shoe. It inflates to provide a lockdown fit in the ankle area. The toe box was designed to be flexible and spacious, allowing natural toe-splay during weightlifting and jumping. Because of the shoe’s unique construction, it is advisable to try it at a local store before purchasing.

The CrossFit Nano Pump Fusion features a rubber outsole with raised lugs to offer traction on a variety of surfaces.

The abrasion-resistant RopePro compound wraps the medial side of the sole for additional protection during rope climbing. It is made of the durable carbon rubber which “bites” the rope on the ascent and guards the platform against friction on the descent.

The MetaSplit expansion grooves in the forefoot section allow the sole to bend in multiple directions. It accommodates natural toe-splay, which is essential in maintaining stability during weightlifting.

The Reebok CrossFit Nano Pump Fusion employs the CMEVA (Compression-molded EVA) foam midsole. Its rebound property serves to deliver responsive cushioning and impact attenuation.

A one-piece cleatie construction of the CrossFit Nano Pump Fusion aims to offer a snug, sock-like fit.

A Kevlar-infused fusion fit sleeve wraps the foot, providing irritation-free coverage and protection against abrasion.

The upper also receives its structure from a synthetic, Kevlar-infused shell. It is placed around the toe box and on the midfoot for 360-degree durability. It features open mesh to retain breathability.

The trainer makes use of the proprietary Pump technology. It features an inflation device near the heel that pumps air into an inflatable unit inside the shoe. The volume of the bladder is regulated to provide a comfortable, lockdown fit in the ankle area.

This unique feature has also been used in some of the brand's basketball and running footwear. It can also be seen on the iconic, basketball-inspired sneaked=r called the Reebok Pump Omni Lite.
