  • The Merrell Agility Fusion Flex is a running shoe that’s designed for the neutral pronator. It has also been configured to work on the trails. It makes use of a semi-aggressive outsole to provide traction over the surfaces. Forefoot flex grooves encourage the natural flexibility of the wearer’s foot.
  • Underfoot cushioning is handled by a full-length foam. It is also tasked with shielding the foot from irregular surfaces and sharp trail debris. A removable footbed contributes more support.
  • A breathable mesh provides breathable coverage for the foot. Reinforcing this material is a synthetic leather cover that’s also meant to stave off the potentially debilitating effects of exposure to the trails. There are additional elements that are designed to hold the foot in place and prevent it from quivering inside the foot-chamber.

Regular measurements were used when the Merrell Agility Fusion Flex was made. Its sizing scheme accommodates the usual choices of consumers. When it comes to width, the options are B – Medium for women and D – Medium for men, and it means that it caters to those who have medium foot-dimensions. The semi-curved shape of this running shoe follows the natural curve of the human foot.

The outsole unit of the Merrell Agility Fusion Flex features a full-length rubber compound known as the M Select™ GRIP. Its job is to protect the midsole from the abrasive nature of the trails. It is also responsible for surface traction.

There are gripping lugs patterned on the external pad. These protrusions are meant to heighten grip over the trails, particularly considering upward and downward traversals.

Flex grooves in the forefoot section allow the platform to bend in conjunction with the joints of the toes. Such a mechanism invigorates the toe-off phase of the gait cycle.

The platform of the Merrell Agility Fusion Flex is comprised of the FLEXconnect™. This full-length ethylene vinyl acetate foam has the purpose of cushioning the landing impact and energizing the toe-off. It has integrated flex grooves in its construction to enable the natural flexibility of the foot.

An EVA footbed adds some more cushioning for the runner. It can be removed or replaced with a custom insert of the runner’s choosing.

Mesh serves as the primary material of the Merrell Agility Fusion Flex’s external façade. It’s a breathable cover that maintains a cool yet secure environment for the foot.

Synthetic leather serves as the overlay system. It’s stitched to the mesh, bolstering it and keeping it protected against the elements. It also helps the traditional lacing system when it comes to locking the foot in place.

A soft fabric serves as the internal sleeve. It staves off skin irritation with its smooth and non-layered construction.
