Running Shoe Review: Columbia Montrail Fluidflex F.K.T.

The Columbia Montrail Fluidflex F.K.T. (F.K.T. stands for fastest known time) is an attractive, lightweight trail running shoe. Is it a shoe that also holds up as a daily trainer for those who run on hard city surfaces? See our verdict below.

One can almost tell by looking at a pair of the new Fluidflex F.K.T. that it has the soul of a fast shoe. It’s just 9.5 ounces in weight, and feels lighter on one’s feet. The shoe has a seamless upper and an outsole that is almost identical to the one on the bottom of the Montrail Fluidflex, circa 2013. According to Columbia Montrail – which provided a sample for review, the Fluidflex offers “enhanced mid-foot stability and a smooth ride on the trail.” Of this, there’s no doubt.

The Fluidflex has a minimal 4mm heel drop and a protective Trail (rock) Shield in the forefoot. The shoe appears to be semi-curved, is slip-lasted for comfort, and provides a snug fit. Notably, the shoe comes with a commercial grade, high quality, aftermarket-looking insole. It’s impressive and means that the runner who buys this shoe will not need to make a post-purchase drive to the local CVS or Walgreens.

The tongue on the Fluidflex is overly short, especially for a trail shoe, but this is a minor quibble. A second quibble has to do with the fit. My narrow feet wished for more headroom in the forefoot and a bit more space on the lateral side. My small toes were crying out for more space! Luckily, the upper loosens up with the passage of miles, so patience has its virtues with the Fluidflex.

On a dirt and rock covered trail one can feel the Fluidflex’s lugs dig in. These lugs may be relatively small but their strength becomes quite apparent on a newly mown grass trail. They dig in so well, so securely, that it feels like one’s running on clawed cat’s feet. Excellent!

On a hard-packed dirt trail, the shoe offers a B to B+ ride. The Fluidflex is just nimble enough to bring out the mountain goat in a runner. On a trail made up of large and small hard rocks the Fluidflex provides all gain and no pain.

Switching to an urban surface of concrete, the Fluidflex delivers straight ahead foot strikes with some bounce but not too much. It’s clear that this is a highly protective shoe, something that’s also apparent on asphalt. And this is a great tempo trainer; lock onto a pace and the shoe will stick to it like an auto set to cruise control. Nice.

The two flex grooves cut into the forefoot of the Fluidflex do indeed provide for a substantial amount of flexibility. This makes it a joy to use as an urban trainer. Whether you are a midfoot or forefoot striker, this shoe will accommodate your style. One caveat about this model is addressed to mild to moderate pronators: the current Fluidflex does not appear to be quite as stable as the earlier Fluidflex and Fluidfeel models – both of which I’ve run in.

This Fluidflex is consistent with earlier offerings from Montrail in terms of delivering on its promised smooth ride. If you ran in the La Sportiva Helios trail shoe, for example, and are looking for a similarly comfortable non-jarring ride, the Fluidflex is one to take out for a test spin.

One final and additional quibble before we arrive at the verdict. Because of the use of foam insoles, city and trail shoes are becoming increasingly soft. I would love to see a model from Columbia Montrail that offers additional firmness from the midfoot through the forefoot. Not a tremendous amount of firmness, but perhaps twenty to thirty percent more than is present in the current Fluidflex.

Verdict

At a price of $110, the Columbia Montrail Fluidflex F.K.T. is a high value shoe. Its build quality is clear and the company has gone above and beyond in terms of details like providing an upgraded insole. While the shoe works well on both country trails and city streets, I believe its pluses are most readily apparent when it is used as a daily townie trainer.

Well recommended.

Running Shoe Review: Montrail FluidFlex

Is the Montrail FluidFlex a WYSIWYG trail runner?

In the past, I had an interesting experience with the Montrail FluidFeel running shoe as it looked like one type of shoe (heavy and bulky) but ran like another type (light and nimble). So I was interested to see if this would be the case with Montrail’s FluidFlex model. Read on to see the verdict.

I came across the FluidFlex at Fleet Feet in Davis, California. The shoe has a surprisingly racing flat-like look for a trail running shoe, but then it weighs only 7.6 ounces; it’s quite light. And it looks bold in coal with red Montrail side lettering and a yellow FluidFoam midsole. I wound up buying the FluidFlex hoping that the shoe might prove to be as light, fast and flexible as it appears to be.

I can say right off that the FluidFlex offers great cushioning in a lightweight shoe. It’s nice to walk in and only the asymmetrical lacing system lets others know that this is not a racing flat. The fit is narrow and secure but not tight because of the highly flexible upper. The fit at the rear of the shoe is exemplary; one’s heels and ankles are well surrounded and protected.

The FluidFlex fosters such a smooth ride while running that I began to think of it as the Montrail Glide runner. The shoe has a floating sock liner which adds to its uniqueness. On the road, the shoe’s high level of flexibility allows the feet to go through the proper landing cycle — heel, then mid-foot, then forefoot. The shoe does not interfere with one’s normal foot strike, and allows the feet to land flat.

The feel of the FluidFlex on roads and trails is quite similar to the Pearl Izumi E:Motion Road N1 and the La Sportiva Helios. On asphalt it simply feels good to run in.

On a track the FluidFlex makes one feel like Steve Prefontaine, possessing the ability to put in some strong, fast laps. The heel padding is soft but the landing is secure and anything but mushy. The fast and steady nature of the shoe is maintained on a crushed gravel trail.

The FluidFlex has a flared sole that supports and reinforces a high level of lateral stability on a hard-packed dirt trail. The hybrid nature of the “town and country” sole underfoot provides just enough grip on a hard-rock trail to keep one traveling straight ahead rather than slipping and sliding. The sole also allows the feet to move sideways while in motion. It may be counter-intuitive but this provides a reassuring measure of stability control.

The FluidFlex feels low-to-the-ground and it has a minimalistic 4mm heel drop. For some runners (especially long-term heel strikers), this will signal the need to break in the shoe slowly and carefully. In my case, I initially experienced some soreness in my calves and stinging in my heels. But this was only temporary.

The Montrail FluidFlex lives up to its name, providing fluid flexibility in a shoe that’s more protective than it’s looks would indicate. While it may be a lightweight shoe, it’s quite durable in use. My well-used pair has minimal signs of wear on its still vibrant black and yellow sole.

Verdict:

The Fluid Flex is a WYSIWYG trail running shoe. It is the shoe that it appears to be and more.

Runners, whether fast or slow, should be able to use this shoe as a trainer on a wide variety of surfaces. It will serve as a good marathon trainer and race day shoe for some competitors and as a fine 5K to half-marathon shoe for many. Joggers with inflexible feet and runners fast enough to chase cheetahs will benefit from the shoe’s ultra-flexible, blown-rubber cushioned forefoot.

The FluidFlex is an excellent trainer to run in even if you never go near a natural trail.

Highly recommended.
