accelerate without a thought pb with codoon 42k
Codoon is a leading sports app in China. Many novice runners joke that if they don't use Codoon to track their run, it feels like they didn't run at all. It helps us stay consistent with our workouts, and watching the track change from green to red is a huge encouragement. As the number of people exercising continues to increase, Codoon is constantly upgrading and optimizing its data collection and analysis capabilities.
How can this data be used to help runners exercise scientifically?Codoon combines technology with sports, resulting in the Codoon smart running shoes. These shoes collect and analyze data during runs, providing personalized coaching that makes exercise more than just physical activity; it teaches people to run smart.
Considering the needs of various runners, Codoon has released smart shoes suitable for 10K and half-marathon distances, focusing on intelligence and cushioning, often described by runners as feeling like 'stepping on poop.' If you watch marathon broadcasts, you'll know that elite runners often choose racing shoes. Major brands have their own highly praised racing series. After extensive research and testing, Codoon's wind-breaking 42K shoes are officially launched, available in Codoon green, black-red, and rose-red on JD crowdfunding.
The packaging remains Codoon green, with only the 'CODOON' logo on the lid. The side of the box displays the shoe size, price, and other information, making it simple and clear. Notably, the price of the Codoon 42K is higher than previous models, priced at 699 yuan, but the initial crowdfunding price on JD is still a friendly 399 yuan.
The pair I received is rose-red with a white sole. The upper is made of double-layer engineered breathable mesh and hot-melt film technology. The use of these two materials creates a visually distinct rose-red color with varying shades, giving it a more layered look. The hot-melt film extends from the upper to the heel, providing excellent wrapping and stability for the entire shoe.
In addition to the conventional anti-kick design at the toe, large anti-collision patches have been added to prevent the toes from piercing the upper during downhill runs due to excessive speed. Many brands omit important features for the sake of lightness, such as the heel stabilization system, but the Codoon 42K includes extensive TPU reinforcement at the heel.
The most crucial part of a good running shoe is, of course, the sole. The Codoon 42K does not use the traditional EVA sole but instead features Codoon's own Acmelight rebound sole. The forefoot and heel areas have added wear-resistant rubber patches, reducing weight while allowing the shoes to adapt to more complex terrains.
I wear size 38 running shoes, and the Codoon 42K feels very light in hand, weighing only 185 grams per shoe, making it the lightest in my current collection. While lightness is important for racing shoes, it shouldn't come at the expense of wrapping and stability, which can only be determined through actual testing. After trying them on, the 42K shoes, designed by a former Adidas and Nike designer, fit snugly on the instep and are comfortably loose on the forefoot. The tongue features an elastic storage pocket to prevent the laces from coming undone.
The fit is so perfect that I didn't want to take them off. Ignoring the smart chip for now, I decided to run a 10K to see if the new shoes needed breaking in before running longer distances. Worried about blisters, I chose a familiar track. As I ran, it felt like I wasn't wearing shoes at all. When I checked my pace, I was surprised to see it was under 4:30, so I slowed down. After 10K, the new shoes showed no signs of causing blisters and were very comfortable.
Back home, I followed the instructions to connect the smart chip to the Codoon app via Bluetooth. Although I couldn't participate in the Beijing Marathon, the Codoon 42K shoes accompanied me for a full marathon to ease my mind. The weather was perfect—foggy at 5 AM, 10 degrees Celsius, no wind, no rain, no sun. My best marathon time was 4 hours and 29 minutes, so I aimed to maintain a 6-minute pace for the first 10K to finish smoothly. After the big hill at 10K, my pace stabilized and gradually increased. The shoes felt light, so my heart rate remained steady. From 16K, I increased my pace to between 5:30 and 5:40. I kept reminding myself that you never know what awaits you in the last 42.195 kilometers of a marathon, so I didn't blindly speed up. From the pace chart, you can see that from 17K to 39K, my pace remained consistent. There was no hitting the wall or slowing down. Even in the dreaded later stages, the Codoon 42K continued to provide rebound from the sole, maintaining support without losing energy. This level of performance is something I've only experienced with the nearly 2,000-yuan Salomon S/LAB Ultra 2.
I completed the marathon in 4 hours and 3 minutes, setting a new personal best and elevating my Codoon level to top-tier one-star. Every runner is excited and thrilled by each personal best, as it signifies recognition and affirmation. During your run, Codoon collects data through the smart chip and analyzes your cadence, stride length, and gait, addressing any issues with your running form. This provides more certainty for your next run. You can also choose from various training programs, including half-marathon and full-marathon courses, making it feel like you have a free personal coach, ensuring each run is effective and efficient.
After several more 10K runs, I have fallen in love with the new Codoon 42K marathon racing shoes. They are comfortable, fit well, have excellent wrapping, and provide great rebound without losing energy in the later stages. As lightweight racing shoes, they may have thinner soles, which might not be ideal for runners seeking cushioning. However, if you are speed-oriented, weigh under 150 pounds, and have a pace under 5:30, these shoes can help you break the 4-hour or even 3-hour marathon barrier. For runners with a pace over 5:30, they can still be used for interval or speed training. Speed is not an issue; you just need clear goals and decisive actions. All you need is a pair of Codoon 42K ultra-light marathon racing shoes.
