Merrell equipped the MQM Flex with their very own M-Select Grip outsole

M-Select Grip is the outsole that lends users the ability to remain surefooted on unpredictable terrain. It is reinforced with the TrailProtect pad (another Merrell exclusive) to bolster the support and protection the shoe offers. Its 3.5-millimeter lugs produce grip no matter if the surface is dry or wet.

These hardwearing lugs are also self-cleaning, which means they are designed to shed most types of debris with every step. The unit slightly encroaches the upper’s toe box for extra protection from trail obstacles.

MQM Flex from Merrell wears a midsole that boasts stability and cushioning

The MQM Flex has a dual-directional flex-groove midsole for stability and underfoot cushioning. Since it is made of ethylene-vinyl acetate (EVA), this component gets to withstand wear and tear for a considerable amount of time. Its heel section is engineered with Merrell’s Air Cushion technology which ups the footwear’s ability to absorb shock upon every heel strike.

For an even more comfortable ride, Merrell designers gave this hiker a removable footbed. It is also made of EVA, leaving it fairly resilient and stress-resistant.

Merrell MQM Flex mesh and TPU upper

Constituting the majority of the MQM Flex’s below-the-ankle upper is a combination of mesh fabric and TPU overlays. Its interior is lined with breathable mesh. Its tongue has its sides sealed to wall off intrusive debris. It has a heel counter called Hyperlock which improves the shoe’s overall rearfoot security.

Giving the foot a firm lockdown is the gear’s classic lace-up closure. A set of plated eyelets and a flat synthetic lace make up its entirety. A strip on the tongue is sewn at strategic points, giving the shoe two lace keepers and a pull tab. Then there’s another loop at the back for easy on and off.
