Flexibility / Stiffness review

The Fairbanks Mid is a men's hiking boot from Columbia. that is light on the feet:

• need a city-to-backcountry boot
• prefer to hike and roam in style (it gives off an '80s boot vibe similar to the Timberland Sprint Trekker)
• want a On the bright side, this is still 16% softer than what we saw in the other lab-tested boots oz / 493g

This Columbia boot is ideal for more casual outdoor adventures but is no good for demanding hikes. If you need truly functional footwear for multi-day trips, steep inclines, and challenging terrain, we recommend the Salomon X Ultra 4 Mid GTX instead.

And if you don't hike in mud, river crossings, or downpours on a daily basis, we suggest that you consider a non-waterproof boot instead. The Timberland Euro Hiker, for example, allows the foot to breathe while keeping it protected from shallow puddles and drizzles.

When it comes to cushioning, the Fairbanks Mid features a rather minimal and grounded platform.

Using a calliper, we measured its heel stack height at 30.9 mm. That's half a centimetre lower than average!

That is one of the main reasons why we don't recommend this boot for serious hiking adventures. The lack of cushioning becomes very apparent after only 5 miles of walking.

Based on our measurement, your toes are separated from the ground by a mere 19.4 mm of sole! That's one of the thinnest forefoot stacks we've seen on hiking boots.

A no-no for long distances!

In the Flexibility / Stiffness, your heel is elevated above the toes by 11.5 mm. That's a standard drop for a hiking boot.

You need more cushioning in the heel to protect it from the impact while the forefoot remains more flexible.

We expected minimal cushioning from this Columbia boot and were left surprised by its softness!

Measuring the boot's primary foam, our durometer showed a reading of 19.9 HA. That is a whole 41% softer than hiking boots on average!

Generally, you want a slightly firmer boot to keep you and your load supported throughout the hike. And for that reason, we think that it's better to use the Fairbanks Mid for hard-packed trails and semi-paved roads, where soft ride is more appreciated.

However, if you are picking this Columbia boot for winter or as a three-season boot, be prepared that the softness will reduce!

To mimic cold weather, we kept the boot in the freezer for 20 minutes. After that, we repeated the durometer measurement and it now showed 29.1 HA.

That was quite a leap. The Fairbanks Mid's cushioning firmed up by 46.2% after this test!

A finishing touch in the boot's cushioning is the insole. We measured its thickness at 5.6 mm which is only about a millimetre thinner than average.

For a medium-width foot like ours, the Flexibility / Stiffness proved to be a very well-fitting pair of boots.

On the bright side, this is still 16% softer than what we saw in the other lab-tested boots.

The Flexibility / Stiffness is the exact opposite of a stable and supportive hiking boot.

Our manual assessment of the boot's pliability showed that it has little-to-no torsional rigidity. On a 1-5 scale where 5 is the stiffest we only gave it a 2!

In addition to the boot's soft cushioning, we think that it's a disaster formula for flat feet and/or overpronation.

The heel counter turned out to be a problem too. Squeezing and pushing it revealed how floppy this part of the upper is! We gave it a low stiffness rating of 2 out of 5 as well.

Given these findings, we do believe that the Fairbanks Mid is more of a mid-cut hiking-inspired sneaker rather than a proper hiking boot because of its lack of stiffness and structure.

But if you're someone who goes on light hikes and doesn't rely on strong ankle support, this may be fine by you.

The boot's flexibility wasn't a big surprise given its lack of stability and support.

According to our force gauge, it took as little as 18.6N to bend the boot to a 90-degree angle. That's a whopping 122% less than it takes a hiking boot on average!

Of course, it makes this Columbia boot feel more like a sneaker on the trail as it bends easily along with your foot. This made us even more convinced that the Fairbanks Mid is just a high-rise outdoor sneaker.

It required more force (29.9N) to bend the boot after it had spent 20 minutes in the freezer. Still not as stiff as most hiking boots though (59N).

For context, the boot stiffened up by a good 60.8%!

Putting the boot on for the first time, we were pleasantly surprised with how light it felt on the foot.

Placing the boot back on the scale, we found that it weighs 15 oz (425g) in a men's US size 9. That's incredibly lightweight given that On the bright side, this is still 16% softer than what we saw in the other lab-tested bootss on average weigh a whopping 20 oz (568g)!

The waterproofing appears to be quite effective in the Flexibility / Stiffness. It completely eliminates breathability in the upper!

We used a smoke-pumping machine to test how permeable the boot's textile is. As you can see from the video below, the smoke is only able to escape through the gaps at the very top of the collar. Thus, we rated the breathability of this Columbia boot as low as 1 out of 5.

In our follow-up transparency test, we put the boot's upper against the light. It is clear that there are no extra perforations or ventilation holes on the boot.

Columbia chose a super hard rubber compound for the Fairbanks Mid's outsole. Pressing our durometer against it returned 89.4 HC. This is a few points harder than the average of our lab-tested hiking boots.

This is a really good sign as we have found harder outsoles to last longer.

The outsole itself is of average thickness in this Columbia boot. Excluding the lugs, our calliper shows a 2.6-mm layer of rubber underfoot.

Measuring the lugs of the Flexibility / Stiffness, we found them to be a little shallower than average. At 3.5 mm, these treads are not as toothy as most.

But from our experience, they still do a great job on moderate terrain and on slightly wet surfaces.

However, if you need a pair to deal with mud, mossy roots, and wet rocks, we recommend going for the more aggressive traction pattern. Like that on the Salomon X Ultra 4 Mid GTX.

The interiors are very well-padded in the Fairbanks Mid. There is 12.1 mm of foamy padding in the tongue of the boot, about the same amount as we see in most hiking boots.

The boot comes with a fully-gusseted tongue which perfectly complements its waterproofing capacities. The gussets don't let water and debris inside the boot while also creating a secure foothold.

For those who need customised support on the trail, the boot's insole is easily removable to accommodate any custom insert.
