Updates to Natural-80

The natural running concept, which Asics uses in many of its most popular and expensive shoes, continues in versions that are generally built for recreational runners. With the introduction of the Natual-80 runners have another option in a shoe that has minimalist features with enough cushioning and support that will not require too much of an investment.

The Natural-80 incorporates a 4mm offset in a low-cut design with plenty of flexibility to bring about the most natural strides of runners. It mimics barefoot running to some degree, but still enough buffer between the road and the feet.

Asics uses a sock-like upper to mold the shoe to the runner’s foot. It even uses an inner sleeve that takes the place of a regular tongue to produce the second-skin effect in the upper.

Natural-80 size and fit

The fit of the Natural-80 is snug in a good way. This is perfectly suited to those who have narrow to average feet. The shoe also offers a natural space for the toes to splay. It offers a bit more room in the forefoot that cramping does not happen during mid-run. Runners will get the standard medium as the available width of this shoe. Sizing is standard in the options 7 to 15 for the men’s and 4 to 11 for the women’s.


The full-contact outsole is covered with AHAR+ rubber for excellent durability and traction. A full-length outsole helps with the movement from the rear to the front. There are horizontal flex grooves that give the shoe great flexibility for natural running.


The midsole is a no-hassle environment consisting of a full-length EVA. It delivers the required cushioning and responsiveness for speed sessions or during race day. The upper is directly attached to the midsole through the California Slip Lasting for added cushioning and structure in a very minimal shoe.


The upper is even simpler than the midsole. It features a really breathable and flexible mesh. There are synthetic overlays that help hold the shoe together. Asics uses its patented logo as part of the midfoot hold. The seamless construction of the upper reduces risks of blisters. As mentioned, the Mono-Sock fit system that replaces the usual tongue provides the sock-like fit and wraparound comfort. Runners can have a more personalized fit and cushioning by replacing the removable sockliner for customized orthotics.
