    If you're a little bit more like me and maybe you're going at a slightly slower pace and maybe you want a little bit more comfort or you're doing longer distances, I think--me in particular--I'm gonna get a lot more wear out of the X-Claw.

    In summary, the X-CLAW is an excellent shoe for those who need a little more comfort, a relaxed drop and a roomier toe box. The shoes perform exceptionally well on all terrain (even road) and if you are out for longer days on the hills, mountains or fells, the 8mm drop and cushioning will make your legs and feet happier.

    The Inov-8 X-Claw 275 makes smart compromises in a lightweight, nimble package that can handle challenging trails as well as multi-hour runs. Our wear-testers had some concerns about the model’s fit and its performance on gentler terrain, but praised its responsiveness and low weight.

    The new version has a bit more cushioning and protection without losing its turn-on-a-dime agility and supreme flexibility.

    Very comfortable shoe. You can feel the extra cushioning, but also feel the ground underneath, which is crucial for most mountain runners when they run on an uneven terrain.

    If you are looking for more stable fell running shoes for a longer distance, you just have to try the X Claw 275.

    Inov-8 has equipped the X-Claw with its Powerflo insole, which is great for shock absorption while still giving you a good feel for the trail. Initially, I was nervous with the amount of feedback I was getting from the trails. I thought that with how much feeling I was getting for the terrain, my feet were going to get beat up after a few miles.

Updates to X-Claw 275

Reliable cushioning, high quality design, and efficient performance; these are just some of the capabilities of the Inov-8 X-Claw 275. This running shoe takes its wearer through the unpredictable terrains with ease and comfort. It doesn’t shortchange its quality performance with untested components. It’s made with strong materials to bring great running outputs.

The upper unit of this running she makes use of durable mesh, which resists the abrasive and aggressive nature of the outdoor topography. A water-repellent coating protects the foot and the interior fabrics of this model from being affected by mild water infiltration. A toecap shields the forefoot area from debris and harmful surfaces.

The Inov-8 X-Claw 275 offers a blend of responsive cushioning and protection from impact. A high quality foam material carries the foot well. It doesn’t break down easily, so it can stay efficient even after many uses. Landing the foot on the ground becomes less taxing to the runner because impact shock is readily attenuated.

The outsole unit utilizes sticky rubbers with different densities. They provide a mix of durable protection, flexible performance, and reliable surface traction. Wet conditions won’t stand a chance when it comes to this shoe’s external layer. Gripping lugs allow the foot to traverse different types of surfaces and surface conditions with ease. Forefoot flexibility is enhanced by the Meta-Flex groove.

X-Claw 275 size and fit

The Inov-8 X-Claw 275 has a standard running shoe length. It comes in sizes that adhere to the regular measurements. The available width for both men and women is medium. It accommodates those with medium sized feet. It has a semi-curved shape, which follows the natural shape of the human foot.


Dual-C blends hard & soft rubber compounds in order to deliver durable protection and enhanced surface grip. It doesn’t wear off easily, so it remains functional through many running sessions.

Gripping lugs are molded symmetrically on the surface of the outsole. Their purpose is to improve surface traction on uneven surfaces. Uphill and downhill treks become easier because of them.

The Meta-Flex groove makes the forefoot area of the platform more flexible and responsive to the movements of the wearer. It’s a helpful way in adding more freedom to the running style, especially when it comes to uneven terrains.


The mid-sole unit of the Inov-8 X-Claw 275 utilizes the PowerFlow foam unit. This high quality material delivers reliable underfoot cushioning that’s comfortable and consistent. It absorbs impact, too. Landing the foot on the ground won’t let the wearer feel immediate discomfort. A springy nature propels the runners forward in an energized manner.

The Two-Arrow Shock-Zone of this model indicates that the mid-sole unit was designed to deliver a balance of underfoot cushioning, impact protection and springy liftoffs.

A Dynamic Fascia Band™ in the mid-sole does the job of the plantar fascia ligament, which is to give off a Windlass Effect or a kick of energy with each step. Those who experience underfoot discomfort when running greatly benefit from such an add-on.


The Inov-8 X-Claw 275 uses synthetic mesh in its upper. It’s durable and resistant to tearing. It doesn’t have an open construction, so debris won’t be able to enter the interior foot-environment.

A water-repellent coating covers the fabrics and protects it from mild water exposure. It basically heightens the confidence of the runner when running on wet surfaces.

A Toe-Cap protects the toes from bumps and encounters with trail debris.
