Tested by labs.
Proven by athletes.
Every number on this page traces back to a named lab, a dated report, or a documented field test, not a marketing script. This is the data behind Blumaka's cushioning, durability, and performance claims, drawn directly from independent biomechanics testing, third-party lab reports, and real-world athlete studies.
Faster off the line.
Stronger through every stride.
Blumaka NonSlip Insoles went head-to-head against each athlete's own stock insole for 190 trials on cleated turf. An independent biomechanics lab tracked the results with 3D marker-based motion capture and embedded force plates in September 2022.
Softer landings.
Cushioning that doesn't quit.
Blumaka foam went through Heeluxe's "Hulk" mechanical impact tester, the industry-standard ASTM F1976 method for footwear cushioning. The independent testing lab measured how much force each insole absorbs, how much energy it returns, and how much of that cushioning survives real mileage.
Blumaka insoles absorb 17% more impact force than the average insole in Heeluxe's testing database.
Blumaka insoles return 14% more energy than the average insole in Heeluxe's testing database. That's a combination Heeluxe's own data shows most foams can't achieve at once.
Cushioning retained after heavy mileage
Two separate Heeluxe durability tests pushed Blumaka foam against other common midsole materials through simulated running miles, tracking how much cushioning height and force-absorption survived.
of cushioning retained after 800 miles, worn by a 265-lb runner, per the Heeluxe Hulk Impact Test, Oct. 2024.
of cushioning or energy return after a 1,140-mile Pacific Crest Trail thru-hike.
of cushioning retained after 1,389 miles, the basis for Blumaka's 1,000-mile cushioning guarantee.
Less pressure.
More comfort, confirmed by testers.
Every shoe pushes back somewhere, and plantar pressure mapping shows exactly where. Lower peak pressure at the heel and forefoot generally means a more comfortable, less fatiguing stride.
Forefoot Pressure
Heel Pressure
In an 8-person Heeluxe wear test rating five Blumaka insole formulations on a 7-point comfort scale, the top-scoring formulation posted the highest overall comfort rating and the lowest heel and forefoot pressure of every variant tested, the data that led Blumaka to select it for production.
41 golfers. Two independent tests.
One insole change.
Thirty-nine club members ran the same test at Harbour Plaza Golf Club, led by PGA instructor Kevin Smeltz alongside a second PGA-affiliated instructor: their own clubs and shoes, first with stock insoles, then with Blumaka insoles swapped in. A launch monitor and dual force plates tracked what changed across all 41 golfers, and the results were independently reviewed.
Field notes from real use.
Connor Moore, M.S., PhD, logged his own driver and fairway-wood distances for three months before switching to Blumaka insoles, then three months after. He adjusted each shot for weather and altitude using on-course tracking technology.
He also reported that insoles which previously needed replacing 4–5 times a year now last him a full season.
