Merrell Men's Mqm Flex 2 GTX Track Shoe

Product Information

The advantage of a non-waterproof shoe with liberal use of mesh is that it’s very comfortable in the heat. I wore the MQM Flex 2 throughout the spring and summer in central Washington State without issues, and I’ve stayed mostly comfortable in temperatures reaching the high 80s Fahrenheit. Interestingly, I’ve found the MQM does run a little warmer than the Moab 2 Ventilator—perhaps because it doesn’t use as much open-weave mesh—but it’s still a much better breather than any Gore-Tex model (including the MQM Flex 2 GTX) out there for summer adventuring. All in all, the changes to the 2.0 version are incremental tweaks and improvements, rather than a wholesale re-design, as Merrell have chosen to build on the solid foundation created with the original MQM Flex GTX product. The weight of the shoes has consequently increased from 648g to 708g, reflecting a sturdier and more durable build for the 2.0 iteration, but the extra 60g per pair isn’t particularly noticeable on foot. Another change is that the 2020 version is 100% vegan friendly, reflecting the growing consumer demand for ethical products. Merrell has a long history of making sturdy, supportive, and well-designed hiking boots, earning themselves a huge fanbase amongst casual and serious hikers alike. Much of those same sensibilities have carried over to the company’s line of trail running shoes, including the MQM Flex 2. Protection is more in-line with a trail running shoe than a burlier hiker like Salomon’s X Ultra 3.

In terms of stability and support, the MQM Flex 2 more closely resembles a burly trail runner than a typical hiking shoe. The heel cup is fairly solid, which helps keep ankle rolls to a minimum, but it doesn’t have the wide footprint or planted feel of a shoe like the Moab 2. That being said, I had no complaints while hauling a load of just under 30 pounds or lighter weights while day hiking. If you’ll be carrying much more weight, however, or just prefer a sturdier shoe, there are plenty of more capable options. For low-tops, the La Sportiva Spire GTX is almost boot-like in its stability, and Salomon’s X Ultra 3 also offers better support.

Designed to bridge trail running and hiking categories, Merrell’s hiking shoe is light and nimble on the trail

I found them to be winners in the comfort department – no blisters or pinch points encountered – and versatile enough for a range of disciplines from hiking to trail running. For everyday adventures that weren’t excessively hardcore, I found them ideal and didn’t have any complaints.

The rest of second-generation MQM Flex is reflective of the original: Merrell did a great job mixing open mesh along the top of the shoe for ventilation with tightly woven mesh and TPU reinforcements in the lower areas most prone to tearing. TPU film and a small rubber toe cap also combine to provide decent protection around the front of the foot. In about four months of use, the uppers are holding up very well, and the same goes for the lacing system and interior of the shoe. One of the things that first caught my attention about the MQM Flex 2 is how comfortable they are on your feet. Not only do they provide plenty of cushioning, but they are also designed to move with your foot as it adjusts to the changing terrain and environment. The aforementioned Quantum Grip sole flexes nicely as you run, enhancing the runner’s connection with the ground at all times. That said, adding a Gore-Tex liner to a shoe—or any garment for that matter—will cut down on the overall breathability of that product. Gore-Tex has come a long way towards improving breathability in general in recent years. However, most waterproof membranes still tend to have a hard time keeping moisture out while allowing perspiration to pass through too. Because of this, I found my feet occasionally getting warm and sweaty, but usually, this only occurred on warmer days.The final modification is to the Gore-Tex membrane. The original MQM Flex had a waterproof membrane constructed by stitching pieces of Gore-Tex material together, but the 2.0 version use an InvisibleFit Gore-Tex with a single piece of seamless material providing wraparound waterproofing.
