Facts

Use - Evident through its name, the Saucony Lanzar Jav is best suited for javelin throw. Its componentry allows for a great foot plant for stable and powerful performance on the tracks. 

Spike Type - Designed to dig into the track surface for optimal grip, pyramid pins are assigned to the track shoe. These are fashioned to be removable for versatile traction, aiding to the varying needs of the athletes. 

Spike Plate - A nylon plate is configured into the outsole of the track spike. It flaunts a good blend of lightness and aggressive grip. It also presents durable qualities, withstanding naturally abrasive track elements.

One of the highly lauded features of the throwing spike is its 3/4-cut upper. This gives the shoe a boot-like form for support and security. 

Hosting the changeable spike pins of the track shoe is the nylon spike plate. It offers a good balance of rigidity and lightness, maximizing durability while decreasing the bulk. 

For added support, Flex Film overlays are welded to the upper. These push the foot into the midsole, locking it in place.

The Saucony Lanzar Jav only runs in men’s sizing scheme and is designed using the standard width. Thus, women are advised to deduct 1.5 from their usual size preference. 

The fit of the track throwing spike is directly influenced by its upper materials. First, the mesh and synthetic upper enables a generous wrap around the contours of the foot. This delivers optimal security and lockdown. Flex Film overlays, meanwhile, increase support and structural integrity.

The outsole of the Saucony Lanzar Jav sports a combination of both rubber outsole and nylon spike plate. Together, these components deliver a good grip on the track surface, promoting stability. 

Similar to the Nike Zoom Rival M 9, the track spike is furnished with a rubber outsole. Aside from increasing the durability of the throwing platform, it also offers good surface traction. This is especially helpful in optimizing the athlete’s balance. Moreover, it employs minimal weight. 

The nylon plate, meanwhile, exhibits a good blend of rigidity and flexibility. While heightening the sturdiness of the track spike, it also promotes natural flex. It is also tasked with housing the pins of the track throwing shoe for versatile traction.

A compression-molded EVA footbed is layered on the midsole of the Lanzar Jav. It is made of high-strength TPU pellets that are heated then cooled down into a mold. Its composition promotes durability and responsiveness. It also cushions the underfoot for plush comfort.

Acting as the outer wrap of the throwing platform are synthetic and mesh upper. The mesh material acts as the ventilation windows of the shoe, intended for breathability. The synthetic material permits superior lockdown, preventing premature removal. 

As mentioned, the upper of the track spike presents a boot-like construction. This is intended to keep the foot locked in place. 

To further support, Flex Film overlays are bonded to the upper. These technical elements are made of thin films that feature no-sew engineering for maximum comfort and irritation-free performance.
