Preface
With the development of the intelligent era, Codoon's slogan has evolved from 'Exercise with Codoon' to 'Intelligent Sports All in Codoon.' This marks the official launch of a new intelligent sports strategy, venturing into the field of intelligent sports equipment. From the initial release of the Codoon smart wristband to smart running shoes, smart sports bras, and the joint release of the iBFree2 smart Bluetooth heart rate sports earphones with 1MORE and Tencent Dingdang, Codoon provides cost-effective intelligent sports equipment for sports enthusiasts.
Today, we introduce the Codoon Smart Running Shoes 21K Ultra-Light Edition, also known as the second-generation 21K. From the name, it's clear that the weight has been reduced. What other optimizations and improvements are there? Find the answers below.
Unboxing
The shoe box features the classic Codoon green, a youthful color scheme that unleashes infinite potential.
The 21K comes in five color options for both men and women. The pair I received is the men's sky blue version, with orange accents that are just right.
Through material optimization and process improvement, the weight has been significantly reduced compared to the previous generation 21K. A single shoe in size 43 weighs 284g, which is excellent for cushioned running shoes.
The upper is different from the previous sandwich material, using a double-layer clamped upper with more breathable mesh holes. Key areas are reinforced with heat-bonding technology.
The collar and tongue are filled with soft foam, providing a comfortable fit that wraps around the foot. The tongue has a thoughtful lace storage pocket to prevent the laces from loosening and disrupting the running rhythm. However, I personally think this design is unnecessary because the laces never come undone. Another small detail is the three-point fixation on the tongue to prevent it from slipping.
The external TPU heel stabilizer locks the heel firmly, making it more suitable for runners who land on their heels. It also features large reflective areas to increase safety during night runs.
The insole is equipped with high-end Ortholite high-elastic insoles from the U.S., with a recessed design and a thickness of 5mm, enhancing the overall cushioning performance of the running shoes. It also has sweat-absorbing, breathable, and antibacterial properties.
The midsole is made of multiple layers of multi-density materials. The white EVA midsole material uses different density segmented cushioning designs based on the contact points of the foot, significantly reducing the risk of impact injuries. The dark part is DUO-HEE elastic midsole material, providing good rebound. The outer heel is equipped with GEL cushioning, making you bounce, bounce, bounce!
The outsole uses different density wear-resistant rubber patches for the forefoot and heel, with the forefoot being slightly softer. The arch area has an anti-torsion TPU patch to enhance stability, and the outsole's center of gravity guide line helps control the runner's center of gravity for stable strides. The groove design of the outsole makes it more flexible, ensuring a smoother transition from heel to toe.
Unlike traditional running shoes, the left insole of the Codoon Smart Running Shoes 21K Ultra-Light Edition houses a new generation smart chip. By binding it to the Codoon app, you can access a wealth of fitness tutorials, with experienced coaches providing full video guidance. There are also voice prompts for warm-up and stretching before and after exercise, and real-time voice reminders during exercise to control cadence, pace, and running form. After exercising, you can view detailed analysis data through the app.
Additionally, the Codoon Smart Running Shoes 21K Ultra-Light Edition has a reward mechanism. You can earn red envelopes and bind the SPC Sports Treasure, where every step counts as money. You can redeem items like the iPhone X, sports equipment, and phone recharge cards for free.
Sports Test
Looking at major running shoe brands worldwide, most focus their core technologies on the midsole and outsole, especially in cushioned running shoes.
Since these are positioned as cushioned running shoes, let's take a slow run to experience their cushioning and protective performance.
In terms of weight, the Codoon Smart Running Shoes 21K Ultra-Light Edition has made significant adjustments, reducing the weight of a single shoe by about 30g. This greatly reduces fatigue during mid-to-long distance runs and is also easy to handle during short-distance sprints.
In terms of cushioning, the four-layer cushioning system composed of Ortholite high-elastic insoles, DUO-HEE elastic midsole material, GEL cushioning, and EVA dual-density midsole material effectively reduces the impact on the knees and ankles upon landing, while the feet can feel the rebound from the sole.
In terms of protection, both the toe and heel have been reinforced. The midfoot TPU anti-torsion device and center of gravity guide line in the sole stabilize your stride, which is especially important when you're fatigued in the later stages of a run. The wear-resistant rubber material and tread design of the outsole provide excellent anti-slip performance on different surfaces.
In terms of comfort, the shoe last suitable for Asians and the strong wrapping feeling enhance the comfort of the running shoes. However, the unavoidable stuffiness of cushioned running shoes is more noticeable in summer.
Conclusion
After more than ten days of running experience, the Codoon Smart Running Shoes 21K Ultra-Light Edition has a good appearance, is equipped with four-layer cushioning and four-layer protection, and keeps the shoe weight within a reasonable range. Although named 21K, these running shoes can help you progress from beginner to full marathon. During the JD crowdfunding period, they are priced at an industry-conscience price of 269 yuan, truly achieving high cost performance. Whether you are a beginner or an experienced runner, give the Codoon Smart Running Shoes 21K Ultra-Light Edition a try.
