  • 88 / 100 | Ultrarunner Podcast

    If your preferred trails are tamer in nature and you like a bit of ground feel this is a good shoe. If you run on more technical terrain with rocks that could bruise your feet if you are not careful I would look for a shoe with more protection.

  • 70 / 100 | The Bearded Runner

    The 270 performs really well on rocky hard terrain, but there are a few glitches… it’s still quite stiff, not particularly comfortable to wear over 10 miles let alone north of 30. But the ride is still good, it still feels fast – as most [I]nov-8 shoes do…

Updates to Inov-8 Trailroc 270

  • The Inov-8 Trailroc 270 is a running shoe that’s designed for the neutral pronator who wants to tackle the trails with ease and confidence. It has a low-to-the-ground profile with a set of midsole elements that help protect and propel the foot forward.
  • Three rubber compounds are used in the outsole unit. These elements work together to deliver precise performance output on the various types of terrain. A single groove near the forefoot encourages the natural flexibility of the wearer’s foot.
  • A seamless upper design allows the wearer to experience a smooth and consistent in-shoe feel. A set of overlays reinforces this section, keeping it upright and intact. A toe cap protects the toes from any abrasive surfaces or debris.

Inov-8 Trailroc 270 size and fit

The Inov-8 Trailroc 270 was designed using the standard measurements. It makes use of a sizing scheme that adheres to the preferences of consumers. The women’s version has a width profile that’s equivalent to B – Medium while the men’s version makes use of the D – Medium profile.

This model follows the ‘3’ determinant in Inov-8’s Fit Scale, which means that it accommodates those who have regular foot dimensions. As an important note, it also follows the Standard Fit design, which means that its forefoot has a wide box that accommodates natural toe-splay.

The Strobel Last is a process that involves stitching the upper is stitched to a full-length fabric on the platform. Its purpose is to heighten durability and allow natural movements to take place.


The Tri-C is an outsole configuration that makes use of three separate rubber compounds to deliver a solid performance on the ground:

The first one is a heel-specific layer called Hard Sticky Rubber. This material offers protection during the foot-strike, staving off the debilitating effects of ground abrasion.

The middle part of the platform features the Soft Sticky Rubber, a reactive piece that potentially heightens underfoot cushioning. Wet surfaces are its focus when it comes to traction.

A Medium Sticky Rubber lines the perimeter, and its purpose is to add extra grip when handling slopes and tricky edges.

A single groove called the Meta-Flex™ permits the joints of the toes to flex naturally during each step, thereby giving a positive performance.


The 1-Arrow Shock Zone is Inov-8’s determinant for a minimum level of cushioning. The platform still has more heel height as it has a 3-millimeter drop, but it’s close to the ground.

The main midsole compound is the Powerflow+. This foam runs the entire length of the Inov-8 Trailroc 270. It’s touted to provide 10% better shock attenuation and 25% more push-off energy.

The Dynamic Fascia Band is a layer in the midsole that acts as the tendons of the foot-pad. It bends during the heel-to-toe transition, then springs back into place during the actual toe-off, thereby giving more energy and bounce. Also, it protects the underfoot from stones and other elements on the trails.


The Inov-8 Trailroc 270 features a seamless mesh. Its purpose is to provide a smooth and irritant-free coverage. It also allows air to enter the foot-chamber with ease.

An External Toe Cap is a fused material that protects the toes from abrasion. It also prevents the nails from digging through the fabric.

The Met-Cradle+ is a set of printed overlays that cover the vital areas of the upper. These thin add-ons bolster the façade and allow it to tighten and loosen in conjunction with the lace-adjustments.

The tongue and collar are slightly padded. The purpose of this design is to cushion the foot, hold it in place, and prevent it from slipping around the interior.
