Delivers grip, durability and flexibility

The bottom of this waterproof shoe is made with a Tri-C Compound. Specific areas are covered with three different kinds of rubber, differentiated by varying colors. On the forefoot is a black-colored medium sticky rubber, giving medium grip and durability.

The grey area is made up of a soft rubber that gives way to flexibility. Lastly, the red hard, sticky rubber which was placed on a high-wear area, the heel, to deliver the most grip and protection against wear and tear.

Roclite 315 GTX can handle hard packed trails 

This shoe was equipped with a Roclite trail outsole which was manufactured with a moderately aggressive lug pattern. The lugs are 6mm in depth. Each one has good spacing in between so debris are not easily trapped.

The lug pattern was intended for hard packed trails and mixed terrain. The arrow-like lugs on the forefoot and back foot face the opposite direction for better grip on the terrains mentioned.

Delivers 15% more energy return

There’s a groove on the forefoot that runs from the side of the shoe to, almost, through the other side. The line can be recognized because it is marked with Meta-Flex. The main purpose of this line is to allow the forefoot to spring forward for more speed and power.

The PowerFlow midsole is incorporated as the shoe’s platform. It is a unique compound by Inov-8 that, compared to standard midsoles, delivers 10% better shock absorption when the runner’s foot lands, and 15% more energy return when the runner toes off or is in motion.

The dynamic results in a protected yet energized ride.

Moderate underfoot cushioning

From the midfoot to the forefoot, an extra plate of protection was added. The plate is called the Meta-Shank. It was formed with a five-finger design.

Each extension aligns with each metatarsal on the foot for enhanced underfoot protection without sacrificing the flexibility. On the back of the midsole platform, there are two arrows marked on the base of the heel.

This indicates that the midsole has a 2 Arrow Shock Zone – moderate underfoot cushioning. Plus, with a heel-to-toe measurement of 8mm, this type of Shock Zone encourages more natural running movement and body alignment.

Inov-8 utilizes Kevlar fibers for durability

The upper has the X-Protec technology which is composed of Kevlar fibers. Kevlar is a heat-resistant and sturdy synthetic fiber which has plenty of applications in the market because of its high tensile strength-to-weight ratio, meaning it’s pretty strong for something light.

On this shoe, it was intended to elevate durability and protection, while still maintaining breathability and lightness.

Waterproof, windproof shoe

Bonded directly to the upper is the Invisible Fit Gore-Tex membrane. Because of this incorporation technique, runners won’t be able to notice that there’s another layer added to make the shoe waterproof and windproof.

The upper is smoother too, minimizing wrinkles, folds, and pressure points, and minimizing the likelihood of skin irritation. The lacing system comes with durable flat laces, connected to the AdapterWeb Cradle.

This design is a synthetic webbing that is concentrated on the midfoot area, slightly locking this part of the foot down as the laces are tightened. Doing this also secures the fit of the shoe.

Elastic AdapterWeb supports the foot

However, the AdapterWeb has elastic characteristics, and it adapts to the natural swelling of the foot while in motion. The tongue has been gusseted, so it integrates to the upper comfortably, preventing debris from entering while providing that additional comfort on the instep.

Inov-8 Roclite 315 GTX supports the heel

To support the heel, the EHC or the External Heel Cage was introduced. This cage wraps around the rear of the foot, providing that moderate hold to the heel while the runner is over the trail.

Inov-8 Roclite 315 GTX offers extra protection

On top of this, the EHC also enhances the fit of the upper, making the runner feel more secure during runs. There is a Toe Cap that contributes to the durability of the upper. Also, its main purpose is to shield the toes from objects that runners can potentially stub their toes on while trail running.

Inov-8 Roclite 315 GTX extra protection

It prevents bruising and injury. There are Gaiter Hooks on the upper to make way for the secure attachment of the All-Terrain Gaiter. The hooks are a convenient auxiliary component for those who wish to attach a Gaiter for extra protection.
