Updates to Inov-8 Roclite 325

  • The outsole of the Inov-8 Roclite 325 features the Tri-C rubber compound which grants the shoe with a reliable grip on various terrains. What’s interesting about this set up is that the outsole is composed of three types of rubber strategically placed in different areas for durability, flexibility, and protection.
  • To enhance the benefit the Tri-C rubber delivers, several claw-shaped gripping lugs that face different directions have been introduced. Each lug has a wide contact area and is scattered sparsely to prevent small debris from getting stuck on the bottom of the shoe. These cleats dig into the terrain, supplying the runner with sufficient adhesion.
  • The second-generation Meta-Shank is placed in the midsole. It is a rock plate that prevents injury from sharp rocks. On top of that, it also gives a bit of rigidity underneath the shoe, aiding in controlling the contouring motion of the foot.
  • Also in the midsole is the PowerFlow which delivers 10% better shock absorption and approximately 15% more energy return compared to standard foam units. All of these advantages can come in handy when trail running since the runner will be able to feel more bounce with each stride.
  • The upper contains the new AdapterWeb met-cradle which was designed to cater to the natural movement and swelling of the foot while the runner is in motion. This technology also improves the fit of the upper, delivering a comfortable yet snug fit.

Size and fit

The Inov-8 Roclite 325 is available in standard running shoe lengths. Runners will be able to procure the shoe in their usual size preferences. However, the brand suggests ordering a half size larger than the typical to assure the best fit.

The width of the shoe is standard. It’s still available in B – Medium and D – Medium, but the toe box was designed to be wider. Based on Inov-8’s website, a standard fit provides more room for the toes to splay. It’s also ideal for runners with wider feet.


The Inov-8 Roclite 325’s outsole is very versatile. It features the Tri-C rubber compound which is made up of three different rubbers: the softer sticky rubber, the endurance rubber, and the hard, sticky rubber. All of these three materials work together to make the shoe more robust and durable. They also provide the shoe with a good amount of grip, so a runner doesn’t have to worry about slipping, even on technical terrains.

Featured on all Inov-8 shoes is the MetaFlex line. This deep, linear indention makes way for the natural flexing of the forefoot, allowing this part of the underfoot to function more naturally. It delivers comfort and ease, without making the runner feel restricted when moving.

Another feature the outsole has is the 6-millimeter lugs that are shaped like claws and have wider contact surfaces. This design helps each lug to easily burrow through the soil and produce a tight grip on the terrain. The spaces between the lugs prevent tiny debris from getting stuck on the shoe’s underfoot.


The midsole has two main features. The first one is the second-generation Meta-Shank by Inov-8. Shanks are supportive structures that diminish the load on a runner’s foot and calf during an ascent. The Meta-Shank does this purpose without being too rigid. Because of its three-finger design and polymer construction, it provides a bit of flexibility while still retaining the protection from impact and sharp objects on the trail.

The second main feature is the PowerFlow which is a two-piece material that delivers 10% better shock absorption because of its special formulation. It also gives approximately 15% more energy return compared to standard foam materials. The result is a ride which is protected yet energetic.

Inside, a removable footbed was added to provide that extra layer of comfort. This insole also serves as an extra piece to protect the bottom of the foot from jagged or sharp objects that runners commonly step one when outdoors.


Mesh makes up the main upper unit. It’s lightweight, so it doesn’t add weight to the shoe. It also permits air to easily go in and out, delivering adequate ventilation at all times during the run.

To add more structure and support to the upper, the AdapterWeb Met-Cradle was added to the midfoot. Connected to the lacing system, it gives the right amount of snugness as it adapts to the movement and swelling of the foot. Because it is concentrated more on the middle part of the upper foot, it steadies the foot and prevents any wobbling.

Another structure that heightens support is the X-Lock heel system which is distinguishable because of its X-formation. This feature doesn’t just help with support, but it also locks the heel in place, minimally immobilizing it, so it doesn’t move around during runs.

On the tip of the shoe is a rubber toe cap which protects the runner from injury from bumping into objects on the trail. This structure also gives the upper a bit of durability.
