Updates to Reebok Trainfusion Nine 3.0

  • The Reebok Trainfusion Nine 3.0 was created to serve as an athletic shoe for low-impact training and everyday wear. It is made lightweight and flexible to accommodate natural foot movements.
  • Unlike its predecessor, the new version uses synthetics instead of leather in its midfoot overlays. It helped to reduce both the weight and the price of the footwear.
  • The Reebok logo has been made smaller and placed at the heel panel. It made the look cleaner and the branding less evident.

Size and fit

The Reebok Trainfusion Nine 3.0 offers versions for both male and female buyers. Men can choose from US sizes 8 to 13, and the women’s sizes are available from US 5 to 11. There is also a choice of half-sizes to help in achieving a precise length. The shoe caters to standard foot dimensions as it comes in men’s D - Medium width and in women’s B - Medium.


The Reebok Trainfusion Nine 3.0 aims at keeping the trainer light on the foot by combining the midsole and the outsole in a single unit. It is a one-piece rubber and foam compound which renders protection and grip without adding excessive underfoot weight.

The bottom of the unit features flex grooves of various orientation and sizes. They enhance the pliability of the footwear to accommodate natural foot flexion.


The 3D Ultralite EVA makes up the foam part of the shoe’s sole unit. Created to be lightweight yet durable, it provides a cushiony ride and absorbs shock upon impact.

A small portion of the EVA protrudes upwards on the medial side of the forefoot section. It contributes to foot stability during side-to-side movements. Another part extends up to cover the front of the trainer, protecting the toes from external bumps. 

The heel-to-toe drop of the Trainfusion Nine 3.0 measures at 9.5 mm. Such a differential is more common for running and walking shoes which implies that the shoe is designed to attenuate impact in the heel section.

The die-cut EVA sockliner is added to boost underfoot cushioning. It has a soft nature and molds to the shape of the wearer’s foot for extra comfort.


The primary coverage of the Reebok Trainfusion Nine 3.0 is comprised of breathable mesh. The ventilation pores allow air to come inside the foot chamber, keeping it fresh and aerated.

The synthetic overlays on both sides of the midfoot add structure to the upper unit. They are integrated with the lacing system to provide a secure and customizable foothold.

Additional synthetic panels are placed on the heel and on the toe box. They reinforce these high-wear areas for added durability. The lateral side of the heel panel features a small Reebok logo for muted branding.

The low-cut design gives the ankle freedom of movement and allows for easy change of direction. However, the heel part of the collar is extended and padded to keep the rearfoot secure and prevent accidental shoe removal.
