     While it could be considered relatively light weight in comparison with many of the shoes, I believe you can do much better, either getting vastly more cushioning for the same weight, with the same cushioning for a vastly lower weight.

    Providing slightly more cushioning with the 4mm heel drop than the more barefoot shoes, such as the 155s, this shoe is perfect if you need a little more forgiveness, but forgiveness done with subtlety.

    Good cushioning in that footbed, along with a really shock absorbing EVA midsole to give you tons of energy-return with every stride.

Updates to Road-X-Treme 220

If speed is what the runner is looking for, then the Inov-8 Road-X-Treme 220 is capable of providing just that. It’s a lightweight shoe that’s meant to allow the wearer to move naturally through the gait cycle while making sure that the foot is protected and well-cushioned. A near-flat platform brings a barefoot-like running experience, while greatly paves the way for the wearer’s natural biomechanics to run its course. It’s comfortable and agreeable to how the runner performs.

The upper unit of this running shoe makes use of breathable fabrics in order to keep the foot well-ventilated. Air is important in providing comfort to the foot because it maintains a dry and cool interior environment. A synthetic webbing locks the foot down and keeps it in place, preventing wobbliness or accidental shoe removals.

Injected foam is used in the mid-sole unit of the Inov-8 Road-X-Treme 220. It delivers resilient cushioning, as well as memory retention. Contoured support, which follows the exact shape of the wearer’s foot, is provided. The mid-sole also has a rigid lever arm that propels the runner forward with each step.

A mix of rubber and EVA makes up the main outsole unit of this running shoe. Aside from protecting the rest of the sole unit from wear and tear, it also adds a bit of cushioning. Flex grooves allow the platform to be more in tune with the natural capability of the foot to bend, especially during the toe-off phase.

Road-X-Treme 220 size and fit

The Inov-8 Road-X-Treme 220 has a standard running shoe length, though the sizing follows the measurements for men. To get the equivalent for women’s sizes, 1.5 sizes should be deducted from the counterpart. The available width is medium, so this shoe accommodates those with medium sized feet. Its semi-curved shape follows the natural curvature of the human foot.

Outsole

The Sticky Fusion Compound is an outsole layer that’s made from a mixture of Ethylene vinyl acetate compound and synthetic rubber. Aside from delivering protection against wear, it also adds a bit more cushioning to the foot. Traction is also part of its purpose.

The DSP Outsole are sets of micro-pods that are triangular in shape. Placed in certain areas of the outsole, they heighten the traction and flexibility the runner gets when wearing the Road-X-Treme 220.

The Meta-Flex groove in the forefoot are encourage natural flexibility, which is helpful when it comes to facilitating a more effective toe-off.

Midsole

Injected EVA is a full-length foam unit that’s responsible for the cushioning that foot receives during each step. It doesn’t break down easily, so it stays effective even after many uses. It has a memory retention capability, basically following the contours of the underfoot in order to give structured support.

The 1-Arrow Shock-Zone™ is a molded mid-sole arrow system that makes the platform highly responsive to the natural movements of the foot. The low-level cushioning is close to the ground and almost follows a barefoot-like running experience.

The Dynamic Fascia Band is a rigid lever arm that runs from the rear to the front of the shoe. It works as a way to propel the runner forward during each toe-off.

Upper

Synthetic Mesh is a lightweight material that’s meant to deliver breathable coverage to the wearer. Air is encouraged to enter the shoe in order to keep the foot cool and dry during the running sessions.

The Met-Cradle is a synthetic webbing in the upper that secures the foot well. It essentially wraps around the foot and keeps it in place, preventing wobbliness and accidental shoe removals.

Additional cushioning is given by the 3mm foot-bed.
