The Kiprun Kipstorm Lab is an ultralight carbon-plated racing shoe for runners chasing personal bests from 5K to the marathon. Its low weight and aggressive shape make it super efficient, but its narrow base can feel unstable. It has enough cushioning for the marathon, though it's a safer choice for shorter races run at faster paces. It suits efficient runners with solid form more than those who need a stable, approachable platform.

Our Verdict
The Kiprun Kipstorm Lab is great for half and full marathon racing. Its exceptionally low weight, protective stack, and well-cushioned forefoot help keep the legs fresh, while its stiff rocker creates smooth transitions over long distances. However, its narrow, aggressive platform can feel unstable as form breaks down, making it better suited to efficient runners.
Exceptionally low weight keeps turnover quick.
Great cushioning provides lasting protection over longer distances.
Strong energy return keeps the ride lively.
The pronounced, stiff rocker creates smooth and efficient transitions.
The narrow midfoot and aggressive shape make it unstable, especially as form fades.
The Kiprun Kipstorm Lab is very good for 5K and 10K racing. Its exceptionally low weight and aggressive geometry help it move quickly at faster paces. However, its forefoot isn't very firm or snappy, making it less efficient than its low weight alone might suggest.
Exceptionally low weight keeps turnover quick.
Strong energy return keeps the ride lively.
The pronounced, stiff rocker creates smooth and efficient transitions.
The forefoot isn’t very firm when compressed, limiting efficiency through toe-off.
The Kiprun Kipstorm Lab is good for long runs. Its protective forefoot and tall stack reduce the strain of repeated impacts, while its low weight and rocker keep it feeling smooth as distance builds. However, its not a stable shoe, so it demands clean form, especially once fatigue sets in.

The pronounced, stiff rocker creates smooth and efficient transitions.
The narrow midfoot and aggressive shape make it unstable, especially as form fades.
The Kiprun Kipstorm Lab is okay for daily training. Although designed primarily for racing, it's light, well-cushioned, and rolls smoothly enough for regular mileage. However, its aggressive plated construction and unstable narrow base make it less forgiving than a conventional trainer, so it makes more sense for faster workouts than relaxed everyday runs.

Test Results
Energy Return
The Kiprun Kipstorm Lab returns energy very well throughout the stride. Both the heel and forefoot rebound efficiently after landing, with the forefoot providing a slightly livelier response.
Strong energy return keeps the ride lively.
The forefoot returns energy well after being compressed. Its soft foam rebounds effectively, helping the platform feel lively as you move toward toe-off.
Heel energy return is very good. The foam rebounds efficiently after landing, though it doesn’t feel as energetic as other top super shoes like the PUMA Fast-R NITRO Elite 3.
Stability
The Kiprun Kipstorm Lab has disappointing stability. Its narrow platform make it easier for the foot to tip off line, while the ungusseted tongue adds little support. The heel is slightly firmer and wider, so initial contact is reasonably controlled for heel strikers. Still, it suits runners with efficient form and faster paces, as the platform firms up a bit more under greater load and feels less unstable than it does at slower speeds.
Wide, relatively firm heel helps make initial contact somewhat controlled.
The narrow midfoot and aggressive shape make it unstable, especially as form fades.
The ungusseted tongue adds little support through the midfoot.
The heel feels fairly soft, mainly because there’s no plate in this area. The foam firms up under greater force, adding a bit more structure at faster paces.
The forefoot is very soft. Its small plate adds little resistance when the foam is compressed, so it feels plush rather than firm and direct like the Nike Vaporfly 4. The foam firms up somewhat when more force is applied at faster paces.
The Kiprun Kipstorm Lab has a full-length J-shaped carbon plate. Because much of the plate curves away from the centerline, it isn't visible in our cross-section and can look like a small forefoot plate. If you're curious, here's what the plate looks like, seen from below.
Cushioning
The Kiprun Kipstorm Lab provides great cushioning overall. The forefoot offers excellent protection, while the heel is comfortably cushioned without feeling overly plush either. Because the midsole continues to absorb impact well over longer distances, the shoe has enough underfoot protection for long distances like the marathon.
Great cushioning provides lasting protection over longer distances.
Forefoot cushioning is particularly amazing.
The Kiprun Kipstorm Lab has good cushioning in the heel. It absorbs impact well enough at all force levels, though it will feel relatively less plush for runners who apply a lot of force when landing.
Bounciness
The Kiprun Kipstorm Lab has good bounciness. The midsole doesn’t compress especially deeply, particularly at the heel, but it rebounds efficiently once loaded. This produces a bouncy sensation that suits racing better than runners seeking a plush ride.
Strong energy return keeps the ride lively.
The midsole doesn’t compress much, so the bounce back is a bit restrained.
Snappiness
The Kiprun Kipstorm Lab feels fairly snappy. Its forefoot isn't especially firm when compressed, but it feels stiff during toe-off, especially at faster paces. Its very pronounced rocker adds to the snap and helps drive the shoe forward.
The pronounced, stiff rocker creates smooth and efficient transitions.
The forefoot isn’t very firm when compressed, limiting efficiency through toe-off.
The forefoot returns a decent amount of energy as it unbends. It adds some snap during toe-off, though the effect isn't explosive either.
The forefoot has good bending stiffness. Its small plate helps the shoe resist flexing near the toes, creating a noticeably stiff toe-off, especially at faster paces.
This model has a very aggressive forefoot rocker that strongly directs the foot toward toe-off. Its overall shape resembles the adidas Adizero Adios Pro Evo 2, though the adidas rocker begins earlier while the Kiprun rises at a steeper angle.
Roll
The Kiprun Kipstorm Lab has a great rolling sensation. Its tall forefoot, pronounced rocker, and stiff construction guide the foot smoothly from landing through toe-off. The transition feels strongly directed and efficient, though the aggressive geometry may feel less natural to runners who prefer a flexible shoe.
The pronounced, stiff rocker creates smooth and efficient transitions.
The rocker is very stiff and takes substantial force to flatten. This helps the shoe retain its curved shape through the stride and maintain a strong rolling sensation during transitions.
The Kiprun Kipstorm Lab has a relatively high stack, with a low-drop platform that gives it a forward-leaning shape similar to the adidas Adizero Adios Pro Evo 2. Its tall stack and pronounced rocker suit runners with efficient form, while the low drop makes the ride feel very aggressive.
True To Size
The Kiprun Kipstorm Lab fits true to size overall, with an exceptionally roomy forefoot and plenty of vertical space. However, it runs somewhat long, so runners between sizes or those seeking a close race-day fit may prefer to size down.
The toe box provides plenty of room in width and height.
The slightly short length leaves limited room for your toes.
The Kiprun Kipstorm Lab fits slightly short, with limited clearance ahead of the big toe. It isn’t dramatically short, but the close fit could become bothersome late in a marathon if your feet tend to swell.
The Kiprun Kipstorm Lab is exceptionally light, even for a racing shoe. It’s much lighter than the Kiprun Kipstorm Elite, its more conventional sibling in the brand’s racing lineup, showing how aggressively the Lab cuts weight to make turnover feel effortless.
Popular Running Shoe Comparisons
The Kiprun Kipstorm Lab is the brand's top racing shoe, built for runners chasing fast times from 5K to the marathon. Any racing shoe that tries to cover such a broad range has to make some compromises. The Kipstorm Lab has great cushioning, which helps for longer races, but it isn't very snappy, which holds it back in shorter races. Runners willing to exchange cushioning for more snap should check out the New Balance SuperComp Elite v6. If you want a bouncier racing shoe with best-in-class energy return, check out the Brooks Hyperion Elite 6.
For a more approachable and stable racer, consider the Kiprun Kipstorm Elite or the Kipstorm Challenger as the brand's entry-level option. For more choices from other brands, check out our recommendations for the best marathon running shoes.
The adidas Adizero Adios Pro Evo 2 and Kiprun Kipstorm Lab are aggressive racing shoes with similarly pronounced forefoot rockers, best suited to efficient runners. The adidas is the better shoe overall for racing: it's lighter, more cushioned, and more energetic. However, its very limited lifespan makes it practical only for elite runners chasing serious times. The Kiprun gives up some raw performance but remains highly competitive. It's also more durable, making it the more sensible choice for most runners.
The Kiprun Kipstorm Elite and Kiprun Kipstorm Lab are carbon-plated racing shoes from the same lineup, but the Lab is the more experimental model. Its main advantage is weight: it delivers similar cushioning and responsiveness in a much lighter package, making it slightly more efficient across race distances. Get the Lab only if you’re chasing the last few percent of performance gains. The Elite offers nearly the same racing ability for less money and has an even bouncier, more energetic ride, making it the better choice for most runners.
The ASICS METASPEED RAY and Kiprun Kipstorm Lab are soft, forefoot-plated racing shoes built for very fast runners. The ASICS is the better shoe overall, with lower weight, better cushioning, and more energy return for runners looking to maximize race-day performance. Both are unstable, but the Kiprun feels slightly more controlled and has a more rocker-driven ride, so get it if you prefer a ride that's not quite as extreme.
Differences Between Sizes And Variants
We bought and tested the Kiprun Kipstorm Lab in men's US size 9, and here's the label for our pair. The pair we purchased is the Light Neon Pink colorway, although we vastly prefer its French name, Rose Bubblegum Fluo, which sounds less like a paint sample and more like a nightclub in Saint-Tropez. This shoe isn't available in wide widths. The design section applies only to the exact model we tested, but we expect other size and gender variants to perform similarly.
