Profile of the New Balance Sigma Aria

Use - With its featherlight composition, the Sigma Aria is designated to last in short-distance running competitions. These can range from 200 meters to 400 meters. The track spike can also accommodate both short and long hurdles. 

Spike Type - The short-range track shoe has an 8-spike configuration. The spike pins that are attached to its plate are pyramid spikes that are ¼ inch in length. These spikes are removable to aid to the varying needs of the contender. 

Spike Plate - A Pebax plate runs full-length in the outsole of the running shoe. It delivers surface traction for a stable and grippy performance. It is also recognized for keeping an ultra-light design while maintaining a durable fashion.

Accommodates longer sprints

The spike plate design of the New Balance Sigma Aria takes after the plate style of the Sigma Harmony.

However, it features a more forgiving engineering with its incorporation of a less rigid material. This is to accommodate athletes who would want to test their skills over longer sprints. 

Sigma Aria delivers sufficient grip 

Although the spike plate of the shoe already generates sufficient grip, a rubber outsole is also added to the componentry of the spike. This is to heighten the strength and traction of the track and field shoe.

Finally, the upper composition of the running platform consists of an engineered knit that allows a sock-like fit to the foot.

Available in unisex sizing

The New Balance Sigma Aria is available in unisex sizing in standard width. It follows men’s regular sizing measurements. Thus women are advised to deduct 1.5 from their usual size. This is to help secure an accurate fit and size.

There are several materials integrated into the shoe’s construction that are responsible for its fit. One of them is the engineered knit upper. 

Classic lace-up closure 

It acts like a second layer of skin, wrapping the foot comfortably and securely. Second, the classic lace-up closure of the short-distance spike gives a dialed-in fit. It disables the possibility of unwanted shoe removal.

Featherlight yet aggressive surface traction

Similar to the makeup of other track and field spikes, the New Balance Sigma Aria is equipped with a full-length Pebax plate. This outsole element permits featherlight yet aggressive surface traction.

Moreover, its rigidity keeps a fair balance of comfort and propulsion. The same spike plate is present in the Nike Zoom Victory Elite 2 and Adidas Adizero MD. 

Maximizes speed

Complementing the Pebax plate is the rubber material implemented on the outsole. This maximizes not only the grip of the shoe but also its sturdiness.

Since the spike plate of the Sigma Aria is engineered with less rigid materials, no midsole component has been integrated within the platform. This is also to keep the weight down to maximize speed.

New Balance Sigma Aria offers a healthy in-shoe environment

As mentioned, the upper of the New Balance Sigma Aria consists of an engineered knit. It is made of synthetic materials that wrap snugly around the contours and shape of the foot.
