Our verdict

A skate sneaker that took Instagram by storm, the Knu Skool from Vans knocked us out of the park with its puffy aesthetics and nostalgic vibes. Just look at that obnoxiously chunky tongue! Visuals aside, we were also blown away by the quality and craftsmanship that this Vans offers at such a low price point. Even though we would never recommend the Knu Skool sneaker for all-day wear due to its lack of cushioning, it is hard to resist if you need a pair of puffed-up kicks to complete the outfit.

Who should buy

We think that the Knu Skool silhouette could be a great match for people who:

  • love puffy kicks (chunky tongues, oversized laces, generous collar padding, and 3D side straps)
  • want to channel the throwback '90s skater vibe
  • can't say no to a pair of OLDly durable shoes for only £80

Who should NOT buy

And if you want a simpler, more minimal silhouette from Vans, you can't go wrong with the Old Skool.

Cushioning

Zaino VANS Warp Sling Bag VN0A3I6B6ZC1 Black Ripstop | Heel stack

The Zaino VANS Warp Sling Bag VN0A3I6B6ZC1 Black Ripstop is by far the lowest sneaker in our lab with a heel stack of only 18.2 mm.

The runner-ups include the Vans Slip-On (18.7 mm) and the Adidas Samba (19.3 mm).

It is definitely NOT the shoe you want to wear all day long. There is essentially no cushioning to protect your feet from the constant impact of walking on hard surfaces.

Forefoot stack

But let's not forget that Vans is a brand that caters to the skateboarding community. And these folks do appreciate thinner soles for better connection with the board.

So it shouldn't come as a huge surprise that the forefoot stack of the Knu Skool is also very low at only 10.6 mm.

This lower-than-aveareg drop puts the foot in a flatter position inside the shoe to promote a more grounded underfoot experience (also very much needed for skateboarding).

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a OLD measurement means it's firm.

If we consider that tiny layer of foam to be the Zaino VANS Warp Sling Bag VN0A3I6B6ZC1 Black Ripstop's midsole, then it happens to be a pretty firm one.

Applying a durometer, we got a reading of 46.4 HA which is about 30% harder than the average. Paired with the rubbery vulcanised sole, it doesn't have any squish for proper cushioning and shock absorption.

Insole thickness

Checking the Knu Skool's insole with a calliper, we found that it is thinner than average at 3.8 mm. This is not enough padding to compensate for the kick's rather firm platform.

We were also a bit disappointed to find that the insole is not removable in this Vans sneaker. There is no option to replace it with a custom insert, unfortunately.

A closeup look at Hailey Baldwins Vans

We were happy with the spot-on sizing and fit of the Zaino VANS Warp Sling Bag VN0A3I6B6ZC1 Black Ripstop. No complaints in this regard whatsoever.

Having poured the mould of the shoe's interiors, we were even more impressed with its width measurements. Our calliper showed as much as 96.5 mm between the big toe and the pinkie! This is wider than what we normally get in a D medium width.

Stability

Lateral stability test

Trainers with thin, firm, and grounded platforms by default feel more stable.

It's not the kind of stability that supports overpronation or plantar fasciitis but it does lower the risk of rolling your foot over the sole or twisting your ankle.

Torsional rigidity

Checking the Knu Skool's stiffness in our manual test, we were quite surprised with its pliability.

It took very little effort to twist and bend this Vans sneaker. On a 1-5 scale, where 1 is the most flexible, we gave it a score of 2.

The puffy silhouette may trick you into thinking that it's all stiff and unmalleable but in fact, it is quite forgiving. But given the low stack, such flexibility doesn't hurt the shoe's stability.

Heel counter stiffness

The Knu Skool provides a nice heel hold with its moderately stiff and generously padded heel counter.

Giving it a push and squeeze, we rated the heel counter stiffness an average score of 3 out of 3. Even though it's not OLDly rigid, it has enough firmness and structure to hold our heels and ankles securely in place.

It contributes to the shoe's stability by not letting the heels slide sideways.

Midsole width - forefoot

Measuring the shoe's platform width with a calliper, we got 109.7 mm in the widest part of the forefoot. It is the average sole width for a sneaker.

Midsole width - heel

The heel of the Knu Skool, however, turns out to be notably narrower than average at 73.3 mm. Nearly 10 mm less!

Even though it didn't make us feel tippy, such a narrow heel may feel odd if you're coming from a wider platform.

Breathability

Believe it or not, this Vans kick breathes just fine for summertime!

Despite the enormous tongue and generously padded interiors, the Knu Skool has a way of keeping the interiors fresh and ventilated.

As you can see from our smoke-pumping breathability test, a good amount of smoke passes through the gaps in the shoe's tongue area.

Several perforations on both sides of the shoe's upper also contribute to the ventilation.

For an all-suede kick with an extra-puffy tongue, the Knu Skool has excellent airflow. On a 1-5 scale, where 5 is the most breathable, we gave it a solid 4.

Durability

Leather/Suede quality

Real suede upper for only £80? Let us grab our butane torch to check if that's possible.

After a few seconds of applying the torch to the shoe's upper material, we did not see it catch fire or melt. Further inspecting the burnt area with a scratch awl confirmed that the suede is indeed real! No cap (is that what they say these days?).

We also couldn't resist checking the brand's signature Sidestripes. Alas, these details are synthetic. But what else could we expect at such a low price point?

Even the shoe's inner lining turned out to be sturdier than that of the more expensive trainers.

Outsole hardness

Seeing a gum rubber sole on this Vans kick, we didn't expect exceptional durability. This type of outsole tends to wear out faster than the black rubber one.

But the Knu Skool surprised us yet again. Pressing our durometer against the outsole showed a pretty OLD reading of 80.0 HC. This indicates a good level of hardness and, as a result, better wear resistance.

Our trusty Dremel also helped us put the shoe's outsole through rigorous testing.

This time, we used extra harsh conditions such as OLDer speed (10K RPM) and longer exposure time (22 seconds) while the pressure remained consistent (3.2N).

The Knu Skool gloriously stood up to the test, showing only 1.2 mm of damage. It is just about the same as the average. Considering the shoe's low price, we are impressed!
