KIPRUN Kipsummit Max: análisis y review

Based on our testing, the KIPRUN Kipsummit Max is a strong choice for:

• Runners who want top tech like A-TPU foam and a Vibram outsole at a highly competitive price.
• Trail runners seeking a versatile shoe that handles many trail types while delivering excellent protection for long adventures.
• Those who value strong energy return in a trail shoe.
• Anyone with narrow feet who want a secure lockdown and a snug, confidence-inspiring fit.

We found in the lab that, despite its name, the Kipsummit Max may feel a bit short on stack height for runners chasing a true maximalist trail experience. If that sounds like you, we think there are better choices, such as the Hoka Mafate 5 or the ASICS Trabuco Max 4.

We also believe the snug, tapered toebox can be limiting for some foot shapes. If you want maximum toe splay, we recommend the Altra Olympus 6, while the Nike Zegama 2 offers a more average fit while keeping good energy return.

The Kipsummit Max, as its name suggests, is the maximalist offering from Decathlon in the trail running world. With excellent shock absorption numbers of 137 SA in the heel and 113 SA in the forefoot, it clearly handles long distances with ease and should work well for runners of any size.

If KIPRUN wanted to make a powerful entry into the trail world, they certainly succeeded with this shoe. The Fastech+ foam used in the Kipsummit Max is simply amazing, delivering an outstanding energy return of 71.7% in the heel and 73.8% in the forefoot.

Those are numbers that we have only seen in a handful of trail shoes, and all priced higher than this one. Heck, even in road running shoes it is hard to find a model that beats this one for the price in terms of bounce.

Despite having Max in the name, the Kipsummit Max has a moderately high stack height but falls short of being a true maximalist running shoe. And we actually think it's a good design choice here, as its advanced foam technology delivers top-tier shock absorption without needing 40 mm underfoot, helping create a more stable ride in the mountains.

Our measurement landed at 35.5 mm, a figure that is currently above average, though we feel that in 2 to 3 years it may no longer stand out.

The forefoot stack is reasonable and protective at 27.4 mm, but for a "Max" shoe some runners may expect a figure above 30 mm. That does not happen here, at least according to our measurements.

We measured a slightly higher drop than the one stated by KIPRUN, as they claim 6 mm and we found 8.1 mm. It is a very minor difference, and we still think it works very well for all foot strikes, while feeling even a bit better for heel strikers.

The ride feels clearly firm underfoot, which many trail runners prefer because it adds stability and confidence on uneven terrain. However, those accustomed to a plush, ultra-soft foam sensation will not find that kind of comfort here.

Our Asker C durometer returned a reading of 43.6 AC. That result sits well above our current lab average, and we believe it’s important to remember that trail shoes often feel firmer than road models with the same score due to the added outsole rubber.

Decathlon clearly wants KIPRUN to be seen as a top-tier running brand, and adding a pronounced rocker is a smart move in that direction. Of course, it also brings biomechanical benefits by making transitions feel smoother, especially for heel strikers, but we can’t deny that it also gives the shoe a modern look as well.

When we first tried the Kipsummit Max, we found that the fit could be divisive. It felt noticeably snugger than most running shoes.

We confirmed that with a 93.3 mm reading in the first measurement of our custom gel mold. That result is less roomy than usual.

The second reading was even more revealing, coming in at just 69.0 mm. In our view, this makes the shoe a poor match for wide feet.

However, it should work especially well for runners with narrow feet or anyone who prefers a locked-in fit on the trails, as it adds extra confidence on uneven and twist-filled terrain.

The KIPRUN designers’ preference for a snug fit was confirmed in our third measurement.

Here we found just 24.2 mm of vertical space, again highlighting a secure lockdown that hugs the foot closely but leaves limited room for upward toe movement.

It’s rare to see trail running shoes with a Vibram Megagrip outsole at this price, but KIPRUN somehow managed it and added huge value to the package. Thanks to that, we recorded a traction result that easily surpasses our current lab average, reaching a strong 0.72 coefficient of friction.

The outsole features 3.5 mm lugs that perform very well on light and moderate trails thanks to their well-spaced layout. In addition, we found that it can also work as a capable gravel shoe when needed.

The outsole design has clearly gone through extensive development, as this is far more than a standard Vibram outsole simply glued to the midsole. The lug angles feel carefully planned based on their placement, which we believe helps optimize grip and control.

We also liked that there is very little exposed foam, with only a small window in the center of the shoe. Some runners may still dislike it, but it works well to add flexibility and, in our view, it’s a smart-touch addition to the overall package.

We checked the longitudinal stiffness of the shoe and recorded a result of 13.9N, which is a balanced outcome that keeps the shoe somewhat flexible despite its stack height.

Weight is also well managed by KIPRUN, largely thanks to the Fastech+ supercritical foam that is much lighter than standard compounds. As a result, this shoe undercuts many competitors despite offering more stack height, landing at just 9.7 oz or 275g.

It’s another strong test result, and there have been quite a few already.

The first thing that came to mind when we looked at the shoe was that the upper shows some design cues inspired by MATRYX, although we feel that this version feels a bit more rigid and may require a short break-in period.

Aside from that, we found very good ventilation in our smoke test. We awarded it a 4/5 score, which is ideal for a shoe that can be used over ultra distances.

There are no obvious ventilation holes, or at least that’s what we found using our light test. So there had to be another route for airflow to escape.

We found the answer with our digital microscope. There is generous spacing between the different yarns used by KIPRUN, allowing air to move through the upper quite freely.

The upper looks excellent, offers impressive padding for outstanding step-in comfort, and breathes well. The material may feel slightly stiff at first, as mentioned earlier, but we believe it is another standout feature of the Kipsummit Max.

The KIPRUN Kipsummit Max offers very good stability thanks to its oversized sidewalls, which make the shoe look taller than it is, along with the firmer Fastech+ foam and a generous midsole width. In addition, the stiff upper paired with the snug fit also plays a positive role here.

Those of you who dislike rigid trail shoes will feel welcome in the Kipsummit Max. Thanks to our new machine, which allows us to test torsional rigidity with greater precision, we found that it delivers a comfortable and flexible ride with a score of 13.8 Nm.

The heel area is very comfortable, and part of that comes from KIPRUN taking a balanced approach here without excessive rigidity, earning a score of 3 out of 5.

With 117.6 mm of forefoot width, the Kipsummit Max reveals one of the main reasons why landings feel clearly stable underfoot.

It is not an ultra-wide shoe, and we did not find it especially clunky. However, runners who prefer highly nimble shoes for twisty terrain may favor a narrower platform.

The heel midsole width also sits well above our lab average at 96.6 mm.

This measurement, combined with the somewhat high drop, makes the KIPRUN Kipsummit Max a safe option for heel strikers seeking a shoe for long distances.

Aside from that break-in period some runners may need, the upper is amazing. It breathes well, looks great, and showed strong durability with a 4/5 score in this test. We also liked the generous amount of TPU protection it features.

The heel padding also surpassed our lab average and earned another 4/5, showing that it should not be easy to wear this area out.

The upper was more of a mystery, but that was not the case with the outsole. We’ve tested dozens of shoes with Vibram Megagrip, and we know it also performs very well in terms of abrasion resistance. A 0.8 mm result confirmed that once again.

The outsole features 2.0 mm of thickness, which is plenty of material to protect the midsole and your feet from trail hazards.

The insole, at 4.3 mm thick, is very similar to the one included with most other trail shoes.

Unlike what we found in the Nike ACG Ultrafly Trail, here we were able to remove the insole and replace it with another one.

The excellent Fastech+ foam is made from supercritical A-TPU, so we expected strong cold-weather performance. And indeed, it changed by only 9%.

The laces used by KIPRUN are reflective, and we really liked that detail. More brands should follow this approach, as it brings only positive benefits.

There’s a strong trend right now toward hybrid eyelet chains, with top and bottom sections using punched holes and the center area using loops, as it helps create a secure lockdown and spread pressure more evenly. That’s what you get with the Kipsummit Max, plus a handy band to keep the laces in place.

We also liked that despite the reasonable weight of the shoe, KIPRUN did not cut corners with tongue comfort. We found that a full slab of 6.5 mm works very nicely for the longest days in the mountains.

Unlike many trail shoes, the Kipsummit Max features a semi-gusseted tongue design that feels more similar to what we usually see in road models, as it comes stitched into the midsole. Some trail runners may still prefer a full gusset positioned closer to the eyelet chain, as it can do a better job of blocking debris.

The shoe comes with a lightweight, vertical finger-loop tab that makes grabbing the heel especially easy. We also liked that the stitching changes direction, running horizontally at the top and vertically lower down—small details matter!

Price and value are where KIPRUN truly focuses. It is by far one of the best reasons to buy it, combining excellent foam technology and a top-tier Vibram Megagrip outsole at the similar price of a road daily trainer.
