Good to know

  • The Inov-8 Roclite 320 GTX has an X-Protec upper. It is made up of Kevlar Fibers that deliver a good deal of protection to the runner while going over various terrains. Because the fibers are tenacious, they also make the shoe durable.
  • Runners don’t have to worry about water getting into the shoe because the upper was designed with the Gore-Tex Technology. The thin membrane keeps water out of the shoe, and it can even withstand water-entry pressures during severe weather, keeping the foot dry at all times.
  • On the platform is the Met-Shank plate which starts from the midfoot and extends to the forefoot. It was made with a five-finger design to cater to each metatarsal, promoting better foot movement while acting as a shield.
  • The outsole is made with the Tri-C compound. Tri-C is made up of three different types of sticky rubber that fulfill a specific purpose. Each key area on the underfoot has a different rubber that promotes better traction and grip on tricky surfaces.
  • To indicate the level of cushioning on Inov-8 shoes, the Arrow System was created. At the back of the shoe, near the base of the heel, Inov-8 marked the Roclite 320 GTX’s midsole with one arrow. This indicates that the platform has a medium level of cushioning, responsiveness, and speed.
  • This is a cleat-type running shoe. The upper extension goes over the ankle to provide added support and protection needed for trail running. Because the ankle is already covered, there is no need for trail gaiters anymore.

The Roclite 320 GTX comes in standard running shoe sizes. Runners who wish to get their pair can make use of their usual lengths as guides. As for the width, it also comes in standard measurements.

For a more accurate fit, users need to take note of Inov-8’s Fit Scale where Grade 1 represents the industry B-fit, while Grade 5, the widest on the scale, represents 2E. Based on some retail sites, the manufacturer suggests ordering a half size larger than usual.

The outsole was made with the Tri-C Sticky Compound. This type of outsole was made with three rubbers with varying levels of stickiness. On the forefoot is the red sticky rubber which has medium grip and durability. The black sticky rubber is softer to provide more flexibility in the areas it is on. Lastly, on the heel is the black sticky rubber which is the most durable rubber out of the three. It was strategically placed on a high-wear area, so it provides the most grip and protection.

This shoe was made with Inov-8’s Roclite trail outsole, which was manufactured with a moderately aggressive lug pattern. The lugs are 6mm in depth, enough to sink into the ground and enhance the outsole’s grip. These are sparsely placed, so tiny debris is not easily stuck in between them. They resemble blunt arrowheads or claws facing different directions. This pattern was intended for terrain that’s diverse and unpredictable.

On the forefoot is a groove called the Meta-Flex. The line can easily be recognized because it is properly labeled. The main purpose of this is to allow the forefoot to bend and spring forward for more speed and power.

The PowerFlow midsole was incorporated as the shoe’s platform. It is Inov-8’s special compound that delivers 10% better shock absorption upon landing, and 15% more energy return as the runner toes off. The result is a run that feels protected but still energetic.

The Meta-Shank is a midsole component that runs from the midfoot to the forefoot. It’s a plate that was added for extra protection. Its design resembles five fingers, with each extension aligning with specific metatarsals on the foot to permit a better range of motion while providing that much-needed protection on the trail.

At the heel part of the midsole, one arrow icon can be observed. This means that the cushioning and responsiveness of the shoe was set to medium. With a drop measurement of 4mm, the platform doesn’t just provide enough cushioning, but it allows runners to have a better feel of the ground.

On the upper is the X-Protec Textile which is composed of Kevlar fibers. Generally, Kevlar has plenty of uses in the market because it is heat-resistant and sturdy. Its high tensile strength-to-weight ratio allows it to be a lightweight yet tough material which is what the Roclite 320 GTX needs. It enhances durability and protection while delivering breathability and lightness.

The upper is water and windproof because of the Gore-Tex Technology. This material goes through several quality tests to ensure that the finished product’s waterproofness lasts for a long time. Even after garnering high mileage, runners can still feel secure while going over water or encountering extreme weather conditions.

The AdapterWeb Cradle is hidden behind the upper, with its bands connected to the lacing system. Tightening the laces also tightens the AdapterWeb, moderately locking the midfoot in place. However, as the foot swells, the cradle adjusts, preventing the feeling of tightness and constriction.

To minimally lock the heel, the External Heel Cage was added. This heel support is shaped like an X and is connected to the top of the lacing. It moderately stabilizes the heel while the runner is in motion. Because a part of the cage extends towards the ankle, it also ensures that the fit is snug on that part of the foot.

The hybrid or gusseted tongue provides the instep with a padded, comfortable feel. It also aids in keeping debris encountered from the trail out of the shoe.

On the tip of the upper is a Toe Cap that protects the toes from getting stubbed. There are plenty of objects on the trail that runners can accidentally bump into. With the tough cap, injuries are prevented, and the durability of the upper is heightened.

The Roclite 320 GTX was designed to be a cleat. The ankle is covered, protected, and supported by the extended upper. Runners don’t have to worry about adding an extra accessory like a gaiter to cover the ankles.
