300 € worth?

Review: CUBE C:68X MTB Shoes

Cube is no longer just known for its bicycles. In recent years, the Bavarian manufacturer has increasingly positioned itself as a full-service provider in its Cube Stores. Whether gloves, helmets, or backpacks—Cube now covers almost the entire range of accessories. With the new CUBE MTB C:68X, the Bavarians aim to do justice to the high-end MTB shoe segment.

Cube MTB Shoes Test
No bargain: cube wants 300 € for its premium MTB shoe. What do you get for that?

If you spend 300 € on a shoe, you're usually in the performance sector and place great value on good power transfer.

But fit and comfort for long rides should not be overlooked either. Can the CUBE MTB C:68X shoe deliver that?

With a price of 300 euros, Cube clearly deviates from the usual price-performance path for which the company is actually known. The shoe is aimed at ambitious bikers and racers – the price tag makes that clear. Less ambitious riders can find a similar shoe with the Peak model from Cube for half the price.

The carbon sole is extremely stiff, the materials appear high-quality, and the surfaces are easy to clean – perfect for muddy trails. A robust toe cap protection further emphasizes its off-road claim. The first impression fits, but the test also revealed clear points of criticism.

Velcro and laces are a thing of the past. In the performance sector, dial closures are essential. Cube uses their own system here.

Criticisms – Details with potential for improvement

Despite the premium claim, there are some weaknesses that are surprising in a shoe of this price range:

  • The insoles are disappointingly thin and offer little support. Anyone who is ambitious on the trails should definitely upgrade here. We couldn't understand the Natural Fit approach that Cube is advertising.
  • The forefoot area cannot be tightened ultimately despite the twist closure. However, it might be different for wider forefeet. This may be due to the individual foot shape of the test person.

The insole is very thin.

The sole provides only subtle support in the footbed. Frequent riders and racers will opt for custom insoles here.

Rapid wear in the heel area

The inside of the Verse is lined with a smooth material to make it easy to slip into the shoe. This is generally very good, but unfortunately, this smooth, leather-like surface material started to peel off slightly from the rest of the shoe after about 120 km on our test shoe, causing a blister on the inside of both the left and right shoe at the heel. Further rapid wear due to the air under the material is inevitable here. A clear case for a complaint.

After about 120 km, the heel area inside our shoe developed blisters.

Strengths – Stiff, clean, robust

What Cube does very well:

  • Extremely stiff sole – ideal for maximum power transfer.
  • Low-maintenance surface to which hardly any dirt adheres.
  • Spare parts for twist locks available.
  • Durable materials that still look great even after many rides.
  • Solid toe protection that guards against damage

Cube knows how to make shoes. Even on long rides, we had no issues with feet falling asleep.

The surfaces are rugged and fine-pored. This provides little hold for dirt and makes maintenance easier.

The durable toe area can withstand longer hike-a-bike sections without damage.
Cube Shoes Processing
The overall craftsmanship of the shoe appears to be very high-quality. Cuttings and seams are very consistent.
Cube Carbon Sole
The carbon sole is super stiff. There's nothing to criticize here.
Cube dial closure spare parts
The twist locks aren't from BOA, but they work well and there are online replacement parts available for them.

Conclusion – Solid race shoe with premium ambitions

The Cube MTB C:68X is a high-quality and thoughtfully designed shoe for sporty riders who value maximum stiffness. Cube knows shoes. However, details like the simple insoles and peeling material on the inside of the heel detract from the overall picture. At a price of 300 €, that shouldn’t be the case. Those willing to invest in better insoles will get a powerful shoe that leaves nothing to be desired.
