There are a few improvements over the previous Odyssey React. Among them, the breathable Jacquard upper is great for better breathability. With a plastic-wrapped heel design, the shoes are also vastly improved over the previous version. For many runners, the added stability comes with better reliability. It is why the bouncy-stable feel proves unique.
The outsole has also been improved over the previous version. With enhanced rubber coverage, the outsole now comes with extra durability. With zigzag grooves, the shoes offer plenty of traction on different flat surfaces. You can use them to run on the track or on the treadmill. They can even be used on wet track conditions with the increased rubber surface which protects the surface from wear. But the design of the outsole also allows the right flexibility in the forefoot. This is why the shoes are a solution to consider when sprinting as well.
The shoes are made to meet the needs of most runners. However, heel support is improved beyond these simple needs. This works great with the new React cushioning. The foam is made to absorb shocks which can be a considerable problem for the joints of runners. But the midsole is not as soft as many would expect. They are reinforced with injected thermoplastic polyurethane to give them the right stiffness. Some customization is also possible. You can add your own sockliner if you’re not satisfied by the standard offering. The result is a comfortable midsole with a 10mm offset.
The sock-like feel of the upper is immediately noticed. Partly due to the new Jacquard fabric, the feel and responsiveness of the upper recommend the shoes for all types of runners. It is also true that the knit fabric is different from what was used just a couple of years ago on different shoes. The upper is now made with a more open knit which allows for improved breathability keeping your feet cooler, especially on the long runs. But the upper is light as well, which only enhances the natural biomechanics of the foot and which is not too demanding on those with overpronation.
But the breathability is only specific to the forefoot and midfoot areas. The heel area of the upper is dominated by inside foam collar lines which improve comfort. Other features of the upper are also worth mentioning. Among them, the neoprene tongue of the Odyssey proves a comfortable option to reduce some of the pressure from the lacing.
Size And Fit
For some runners, the Odyssey React can be narrow in the forefoot. If you have wider feet, it is recommended to go half-size up if you want the right fit and proper comfort. If you have flat feet, the shoes might also not be the best option for arch support.
