  • This new iteration of the MQM Flex features a tear-resistant athletic upper, a flexible cushioned midsole, and a quantum grip outsole with deeper, more aggressive lugs for fast and protected movement on the trail.
  • It is lined with the Gore-Tex waterproof membrane that is heat-bonded within the upper for fool-proof protection against rain or water.
  • The Merrell MQM Flex 2 Gore-tex low hiking shoes are also equipped with a heel air cushion for shock absorption, rock plate for underfoot protection, a TPU toe cap, and a removable footbed.

The MQM Flex 2 GTX is a low-cut model that promotes freedom of movement. It has a tongue-integrated lacing system for a more secure fit, along with padded collar and tongue for support and comfort. The pull loop at the back also helps with wearing or taking it off easily.

This shoe features a mountain-grade Quantum Grip outsole with 5mm-deep lugs. There are wide spaces between the lugs so that mud and dirt don't get stuck in between. The grooves on the heel and toe areas help avoid the wearer from slipping or sliding on slick surfaces.

The Merrell MQM Flex 2 Gore-Tex men's and women's shoes have cushioned midsoles that have dual-directional flex grooves for stability, speed, and ground connection. They also come with removable footbeds that are contoured to the feet. Plus, these insoles are breathable, soft, and supportive.

Combing the features of a trail runner and a hiker, the MQM Flex 2 GTX is constructed with performance mesh uppers with TPU toe caps for protection. There's a cushioning system in the heel that absorbs shock and keeps it stable. Lining the shoe interior is the Gore-Tex Invisible Fit that is bonded directly into the shoe for a lightweight, sock-like fit. Even though waterproof hikers tend to overheat, the mesh upper makes way for some breathability. Also, since this shoe is a low-cut model, the feet are likely to stay cool even in really hot days.

Completing the upper is a traditional lace-up closure that is integrated into the tongue for a more secure fit. There's a bellows tongue that keeps the debris out and a rock plate underneath the insole that provides underfoot protection against sharp rocks and stone bruises.

-No animal products were used in the Merrell MQM Flex 2 Gore-Tex which makes it a vegan-friendly product.
