Good to know
- Known among Asics fans as the most cushioned shoe in the 33 series, the 2nd version of the 33-M features softer cushioning as Asics opts to give runners enhanced natural running motion, flexibility, and comfort.
- Asics also took away a substantial portion of the overlays of the past model. The Asics logo practically functions as the main support, especially in the midfoot. It helps the shoe keep a very low weight despite the maximum cushioning. One very simple overlay holds the heel in place as opposed to the heavy support in the original model. This overlay provides decent support while giving the heel a more flexible and comfortable fit.
- The mesh is made of bigger holes in the 33-M 2, particularly in the midfoot and the forefoot. This makes running very breathable.
- There are also new cuts in the outsole’s midfoot. The new cuts run sidewise or from the medial to the lateral side. This update naturally increases flexibility and transition from the rear to the front.
A last Asics calls as the Natural33 gives adequate fit in the heel and midfoot with a generous toe box. Since it mimics the foot’s natural shape, most runners will find the fit very comfortable. This is the same fit used in the last version and in every version under the 33 line. Available widths are medium while sizes are standard. The men’s options are from 6 to 15 while the women’s are from 4 to 12.
Asics utilizes the brand-exclusive DuraSponge Outsole in the forefoot for a bit of flexibility, cushioning, and traction. This material has been used in some popular Asics running shoes like the Kayano 25 and Nimbus 21. The heel features the tougher AHAR carbon rubber for better protection against wear and tear. There are flex grooves designed to work with the foot’s natural movements in the outsole as well.
Asics’ top of the line midsole foam in the Solyte performs the responsive cushioning features of the shoe. As this is slightly firmer, it gives a very nice platform for takeoffs.
A foam that is a little softer than the Solyte is the Amplifoam. This is a full-length and more cushioned foam sitting on top of the Solyte. This gives the midsole a very nice blend of durability and responsiveness in an extremely light package.
A combination of open mesh for excellent breathability and synthetic overlays for support and adaptive fit makes up a large portion of the upper. The seamless construction of the upper creates a very smooth interior that reduces rubbing or irritation.
Asics includes the anti-bacterial properties of the ComforDry Sockliner in the shoe’s features. It adds a bit of cushioning to the shoe as well.
Finally, the Natural 33 Last is designed to follow the human footprint for a more natural and comfortable fit.
