Updates to Reebok ZPump Fusion 2.5

  • The Reebok ZPump Fusion 2.5 is a road running shoe that’s made for runners who have neutral foot motion. The modern-looking façade looks to accommodate the preferences of contemporary shoe enthusiasts. It has a wide array of color schemes that make this shoe more visually appealing. In terms of functionality, this model has unique technologies that accommodate the actual shape, motion and performance of the wearer’s foot.
  • One of the most prominent technologies that are present in this running shoe is The Pump, which is an interior fit system that can be manipulated in order to make the upper unit more agreeable to the shape and form of the foot that’s inside it. It’s basically an inflatable frame that surrounds the upper. The runner only needs to press a button located in the lateral side in order for the material to work. The cover system becomes more customizable because of it.
  • The mid-sole unit of the Reebok ZPump Fusion 2.5 features carbonated foam, a high-quality material that’s very responsive and flexible. It’s also lightweight, so it won’t make the runner feel as if they’re being dragged down by the platform of this shoe. It has some nodes in the external area, which act like cushioning pistons.
  • Durable rubber covers areas of the foam unit that are more susceptible to wear and tear. It’s durable and long-lasting. It also provides reliable surface traction, a very important quality that enables the runner to take control over their movements on the asphalt.

Size and fit

The Reebok ZPump Fusion 2.5 has a standard running shoe length. The available width is medium. It accommodates the runners who have medium sized feet. Its semi-curved shape adheres nicely to the natural curve of the human foot.


CRTek is made from a durable rubber compound that’s highly resistant to abrasion. It shields sections of the sole unit from the potentially damaging nature of the asphalt. It also provides reliable surface traction.

Flex notches in the outsole allow the foot to move naturally through the gait cycle. They make the platform more flexible and agreeable to the foot’s movements.


Carbonated foam is the mid-sole unit of the Reebok ZPump Fusion 2.5. It carries the foot well, cushioning it as it goes through the gait cycle. It’s flexible, lightweight and responsive, too. Several nodes in the bottom section act as pistons that deliver structured cushioning whenever it’s needed.

A reinforced mid-foot tuck board supports the arch of the foot and adds torsional rigidity, which essentially makes each heel-to-toe transition much easier and smoother.

A molded PU sock liner actually adds a bit more responsive cushioning to the underfoot. It’s lightweight and flexible.


The upper unit of the Reebok ZPump Fusion 2.5 makes use of a seamless design. It doesn’t use any thick layers or unnecessary stitching, which is actually very helpful in terms of preventing skin irritation or the onset of blisters. It’s breathable, as well.

The Pump technology is made from an inflatable material. It covers the medial, lateral and rear sections of the upper. A button in the lateral side causes air to enter the inflatable material and make the coverage more agreeable to the preferences of the wearer.

The Powerframe is a sturdy, yet elastic cage that supports the upper fabrics and the Pump tech. It reinforces the cover system and keeps the foot in place.

A pull-tab on the heel of the ZPump Fusion 2.5 makes wearing and removing the shoe much easier.
