Korea Consumer Agency finds carbon running shoes differ by model in tests
En breve
South Korea's Korea Consumer Agency published test results on October 6 for carbon running shoes from seven brands, finding differences in shock absorption, knee fatigue and durability. Nike and Puma models rated relatively well on shock absorption, Hoka on distributing foot pressure, and prices ranged from 189,000 won for Skechers to 279,000 won for Hoka. All seven met hazardous-substance standards, but Adidas, Puma and Hoka needed labeling corrections.

South Korea's Korea Consumer Agency released test and evaluation results on October 6 for carbon running shoes sold under seven brands, finding that functional performance and durability differ by product. The brands covered were Nike, New Balance, Skechers, Adidas, Asics, Puma and Hoka. [ 1 , 2 , 3 , 4 , 5 , 6 ]
On performance, Nike's Zoom Fly 6 and Puma's Deviate Nitro 4 were rated relatively good at absorbing the impact on the heel, while all seven products were rated good on propulsion. Hoka's Skyward X rated best at distributing the pressure the sole takes while running, and Nike rated best at keeping the body's centre of gravity moving stably. Skechers and Asics were rated relatively strong on maximum traction, which Seoul Economic Daily described as the degree of not slipping. Five products — New Balance's SC Trainer V3, Skechers' Aero Spark, Asics' Magic Speed 5, Puma's Deviate Nitro 4 and Hoka's Skyward X — rated relatively well on knee fatigue. [ 2 , 3 , 4 , 5 ]
On durability, four products — New Balance, Adidas's Adistar BYD, Asics and Hoka — rated relatively good on the adhesion strength between upper and outsole. All products met the applicable standard for outsole wear, with Hoka wearing the least at 2.4mm, and all seven met the standard for upper and lining abrasion resistance. Testing for five hazardous substances, including formaldehyde, found all seven products within relevant standards, so the agency reported no safety problems. Labeling, however, required improvement in some cases: Adidas, Puma and Hoka products had inaccurate blend-ratio or material labeling or missing lining labels, and the companies replied to the agency that they had improved the labeling or would do so. [ 2 , 3 , 4 ]
On price, Skechers' Aero Spark was the cheapest at 189,000 won and Hoka's Skyward X the most expensive at 279,000 won, a gap of up to 90,000 won. At 270mm size, Asics was the lightest at 198g and Hoka the heaviest at 301g. Puma's Deviate Nitro 4 recorded the highest wearing satisfaction at 4.6 points, and all seven products scored 4.0 or higher. [ 2 , 3 , 4 , 5 ]
The agency said the results came from measuring 30 consumers running on a treadmill at a constant speed, repeated three times, along with a survey and functional and quality tests; Seoul Economic Daily and ZDNet Korea described the panel as 30 men in their 20s who tried the shoes on and ran. The agency recommended comparing foot pressure, shock absorption and propulsion, and durability such as adhesion strength, alongside price when choosing. It also said that while carbon running shoes can help shorten times, they can burden the ankles or calves of beginners, and advised trying shoes on in the afternoon, when feet swell, and choosing a product with 0.5–1cm of room at the toes. Maeil Business also said carbon shoes offer a 1–2 percent time improvement for elite athletes, a figure the other documents do not give. [ 2 , 3 , 4 , 5 ]
Por qué importa
The results give runners a comparison basis for shoes whose prices differ by up to 90,000 won, and they flag labeling gaps consumers use to check materials. The agency also said carbon shoes can burden the ankles or calves of beginners, a caution aimed at the running market the outlets describe as growing.

- The composition of the test panel. Yonhap says 30 consumers took part in biomechanical performance evaluation and a survey, while Seoul Economic Daily and ZDNet Korea describe the panel as 30 men in their 20s who wore the shoes and ran.
- Whether the labeling corrections by Adidas, Puma and Hoka have been completed. The documents say only that the companies replied to the agency that they had improved the labeling or planned to do so.
- The claim that carbon shoes cut times by 1–2 percent for elite athletes. Only Maeil Business states this figure; no other document gives a performance-effect estimate.
