Description

Minimalist shoe with superior flexibility and cushioning.

As you might guess from the name of the Montrail Men's FluidFlex Trail Running Shoe, supreme flexibility is its calling card. The articulated flex grooves in the sole allow total foot mobility, while a low drop enables a natural forefoot-strike stride. You'll get plenty of cushioning from the FluidFoam in the midsole, too, which even after three months of wear offers 7% more impact absorption than standard EVA, eliminating the need for gel pods or air cushions or other such gimmicks. A hybrid that you can wear out the door to the trailhead, the FluidFlex is ready to go with the flow.

  • Breathable upper mesh offers a snug, supportive allover fit without excessive overlays to add weight
  • Full-length, one-piece FluidFlex midsole features articulated flex grooves that move with the natural motion of your foot
  • FluidFoam in midsole offers better energy absorption, flexibility, and cushioning than EVA, from which it's derived
  • 4mm drop and relatively low stack heights delivers a secure, close-to-the-ground feeling
  • Microlugs in the Gryptonite outsole offer secure traction on a variety of surfaces from wet roads to fire trails

Decent, but not the best

  • Familiarity: I've used it several times
  • Fit: True to size

These shoes are super light, the fit is good and they have great traction. I didn't care for the foam though(a little squishy) and the back of the heel cup is too high for me(afraid it will lead to chaffing).

If you want lightweight without sacrificing cushion, this would probably be a good choice.

Not for me.

  • Familiarity: I've used it several times

I wear this shoe in an 11 for the length, and perhaps (at least some of) the shortcomings I found are a results of a too-wide-for-me toe box in that size. I found this shoe to be sloppy. I didn't feel that it stayed planted through a running stride. My second issue, however is less about fit. The soft foam of this shoe was problematic. It added to an insecure squishiness and the feeling that the shoe was moving under me (when it was supposed to be in place). Despite that thick squish of sole, the soft foam didn't protect well against rocks. I felt them more clearly (ie uncomfortably) than in any of the other shoes I run in. So for me, the foam was too thick to provide good response and connection to the ground, but not stiff enough to protect against terrain.

On the other hand, it is a very lightweight shoe.

Off the charts!

I have run almost exclusively in Montrail shoes over the last few years. I thought the Rogue Racer was a breakthrough in providing great feel and cushioning at an astonishingly light weight. The Rogue Fly, which I also loved, felt like an incremental improvement, shaving a little weight with no discernible loss of performance. I wore both shoes in 20+ trail races. My only criticism was that the forefoot protection felt just a little too minimal (not comfortable over sharp rocks!) and the heel stack felt just a little too high.

Maybe Montrail were listening to me. Or maybe they got the same feedback from a lot of athletes. Because the FluidFlex is an *awesome* shoe that remedies these issues. The forefoot sole is thicker and provides more protection, but still retains remarkably good trail feel. The heel is dropped slightly, giving a flatter, lower-profile, more stable platform. And the weight remains feather-light, not discernibly different to the Rogue Fly.

After using the shoes in only a couple of training runs, I felt comfortable enough to race a 50k in them, and a 50-miler two weeks later.

I still have absolutely no complaints. These are close to perfection.

Responded on

One caveat: Just in case it is not clear from the product description and the given weight of the shoe, this is an ultra-light minimal shoe. There is almost no structure to the upper. Don't buy this shoe if you require stability control or a lot of support.

couldn't agree less. I try many different shoes, and overall think Montrail makes superior products. But this one strikes out. HORRIBLE shoe. DON'T BUY!!!!!

@myobirth894912, what was it that you didn't like about the shoe? Can you be more specific?
