Profile of the Reebok Flexagon 3

What is it for? This pair of training shoes from Reebok is designed for people who do high-intensity interval workouts. These types of activities require adequate underfoot protection when doing jumping exercises, flexibility at the forefoot for burpees, sled pushes and the likes, and stability at the heel for squats and lifting weights.

Though it is made for gym or studio use, its style makes it easy for wearers to sport them out in the streets. The underside is designed to withstand walking on rough surfaces.

What’s new? At first look, you won’t see any difference between the Flexagon 3 and the Reebok Flexagon 2.0. However, the type of midsole used for each model is where the improvement lies. The Flexagon 2.0 uses EVA foam, while the Flexagon 3 is equipped with FuelFoam, which is said to be more reactive to energy than traditional foam.


Traction. The foam unit of the Reebok Flexagon 3 serves as both the midsole and the outsole. The bottom section is crafted to be more durable to avert early deterioration.

Movement. The outsole features deep grooves and siping throughout the surface. These lines aid in the smooth heel-to-toe transition and the overall flexibility of the sole unit.


Responsive cushioning. FuelFoam makes up the midsole of the Flexagon 3. This foam is created to be soft and pliable to aid in natural movements. FuelFoam dulls the impact of foot landings and, at the same time, converts that energy into power for explosive take-offs.

Steadiness. The heel of this training shoe flares out. It creates a wide base that keeps the rearfoot steady during agile movements.


Comfy wrap. The Reebok Flexagon 3 uses a mesh fabric for its top. This material is soft, allowing it to fit and more like a sock. The interior is covered with a soft cloth that amplifies the cozy in-shoe experience.

Perforations are present throughout the top. They help dissipate heat to regulate temperature and moisture inside the footwear.

Protection and support. Synthetic and fabric overlays are used on the upper of the Flexagon 3. They reinforce the underlying mesh against abrasion. They also help maintain the shape of the top for a reliable hold.

Lockdown. A traditional lacing system is used for the closure of this Reebok trainer. It is used to adjust how tight or how loose the midfoot feel for the user.

Light foam lines the tongue and the collar of the footgear. The lining improves heel hold to avoid blistering. The plushness also prevents the shoe from flying off while exercising.
