- The latest version of the MQM Flex features the addition of the mountain-grade Quantum Grip rubber compound designed for traversing rugged terrain. It offers enhanced grip and traction in wet or dry surfaces. It also features a deeper lug depth for additional traction on the trail.
- For the midsole, this latest version of the MQM Flex has grooves that are cut into the actual midsole to help the shoe move more naturally with the foot.
- Its upper is made of mesh and TPU that offer protection against varying trail hazards.
The MQM Flex 2 is a low-cut hiker which means the shaft runs just below the ankle, giving the foot more freedom of movement. Low-cut models make an ideal choice of footwear for experienced hikers. It's also great for traversing well-maintained trails. For a more secure fit, the tongue is integrated into the lacing system. Thus, it stays in place no matter how fast the wearer walks or what direction he or she's taking. Lastly, the web laces make adjusting the fit fast and easy.
This hiking shoe from Merrell features an aggressive outsole with 5mm lugs. Such a lug depth makes the shoe bite into loose dirt, soft grass, gravel, and mud. As an update to the first version, the MQM Flex 2 gets even more grippy with the addition of the Quantum grip rubber compound. It's a durable, very sticky rubber that's ideal for both dry and wet conditions.
For the midsole, this shoe utilizes EVA foam which is known for its flexibility and high energy return. The midsole is enhanced by cutting dual-directional grooves (called FLEXconnect) that are meant to boost ground connection. They allow the midsole to bend and flex with the foot. For added cushioning and support, the MQM Flex 2 comes with a removable contoured footbed.
The shoe upper is made with performance mesh with TPU overlays for durability and support. There is no waterproof lining so it is highly breathable but to the expense of getting your foot wet when it rains. Thus, this shoe is best for hiking in the summer.
This hiker also features the Merrell Air Cushion in the heel which works by absorbing shock and enhancing stability. There's also a rock plate for more support. Completing the upper is a tongue-integrated lacing system with bellows tongue that keeps the debris out.
