MQM Flex 2 GTX updates

A proud successor to the original Flex GTX, this hiker has been given enough upgrades to improve the hiker’s odds on the trail. Its notable improvements are as follows:

Deeper lugs. These hard-wearing studs offer extra bite on loose soil. They work in concert with the ridges on both ends of the outsole to deliver improved slip resistance on ascents and descents.

Reimagined midsole. With its cushy midsole more flexible than ever, trail-goers can have a better feel of the ground. It also propels their stride, allowing for bolder maneuvers as they pick up the pace and build momentum.

Reassuring heel. Unlike its predecessor, the MQM Flex 2 GTX comes with a fanned-out heel, which provides enhanced stability on uneven terrain.

Additional info

  • If you only hike where moisture is not a factor, consider the non-waterproof MQM Flex 2 instead.
