The NK30 is a long-type air-inflatable knee support designed to cover not only the central knee area but also the lower thigh and upper calf.
After putting on the product, air is added using the hand pump. The amount of air and level of support can be adjusted according to the user's body shape and wearing condition.
The NK30 features a long-type structure extending from the knee joint to the lower thigh and upper calf.
It is designed to cover a broader area around the knee, making it suitable for situations where support beyond the central knee area is desired.
The NK30 is inflated after being worn using the included hand pump.
Because the user can directly control the amount of air, the level of compression and support can be adjusted according to body shape and wearing condition.
Pressing the button in the center of the air inlet allows air to be released from the product.
If the product feels too tight after inflation, air can be released gradually until a comfortable level is reached.
The NK30 is designed for situations where support over a broader area around the knee is needed.
When you want support not only around the knee but also around the lower thigh and upper calf
When you prefer a wider support range than a conventional short knee support
When stable knee support is desired during walking or everyday activities
When participating in activities that involve frequent knee movement, such as hiking or trekking
When you want a product that allows you to directly adjust the amount of air
When you prefer a long-type knee support
The main differences are the support range and the air-pressure adjustment system.
Whereas a conventional knee-centered support mainly wraps around the knee area, the NK30 combines a long-type structure that extends above and below the knee with an air-inflatable system.
| Category | Conventional Knee-Centered Support | NK30 |
|---|---|---|
| Conventional Knee-Centered Support | Mainly around the knee | Knee + lower thigh + upper calf |
| Product Length | Standard or short type | Long type |
| Air Inflation | Varies by product | Hand-pump system |
| User Adjustment | Mainly strap tension and material elasticity | Fixation structure + air volume adjustment |
| Key Features | Knee-centered support | Broader support around the knee area |

and do not indicate a medical treatment effect of the product. Individual experiences may vary.
For the NK30, it is advisable to measure not only the circumference around the center of the knee but also the circumference of the lower thigh and upper calf, then compare the measurements with the official size chart.
Because the NK30 is a long-type product that covers areas above and below the knee, it is important to check the circumference of all areas that will come into contact with the product rather than relying only on the knee measurement.
If your measurements fall between sizes, we recommend checking both thigh and calf circumference and selecting according to the official sizing criteria.
The main differences between the NK30 and NK10 are the support range and overall product length.
It is best to compare them based on the level of support required and the intended activity environment.
| Category | NK10 | NK30 |
|---|---|---|
| Product Design | Short type | Long type |
| Main Support Area | Mainly around the knee | Knee + lower thigh + upper calf |
| Air Inflation | Air-inflatable system | Air-inflatable system |
| Structural Feature | Relatively short and compact structure | Structure covering a broader area around the knee |
| Conventional Knee-Centered Support | Focused | Extended |
The NK30 is sold as a single unit for one knee.
If you plan to wear the product on both knees, you will need to purchase the required quantity separately.
Connect the included hand pump to the air inlet and press the pump to inflate the product.
Once the desired fit is reached, remove the pump and use the product. If the pressure feels too strong, press the button in the center of the air inlet to release air gradually.
If you are using the NK30 for the first time, we recommend reviewing the user manual included with the product before wearing it.
Measure the circumference around the center of the knee as well as the lower thigh and upper calf, then select the appropriate size according to the official size chart.
Because the NK30 is a long-type product that covers areas above and below the knee, it is important to check the circumference of the actual areas that will come into contact with the product rather than selecting a size based only on the knee circumference.
If your measurements fall between sizes, check not only the knee circumference but also the thigh and calf measurements.
In particular, if you have more developed thighs or calves, choosing a size that is too small may result in a tight fit.
We recommend comparing the measurements for each area with the official size chart before selecting a size.
The main difference is the product length and support range.
The NK10 is a short-type product designed to support the central knee area,
while the NK30 is a long-type product designed to cover a broader area extending from the knee to the lower thigh and upper calf.
Rather than one product being superior to the other, it is best to compare them based on the required support range and wearing environment.
Yes. The NK30 is sold as a single unit for one knee.
If you want to wear it on both knees, you will need one unit for each knee.
Pressing the button in the center of the air inlet allows air to be released from the product.
If the product feels too tight while being worn, release the air gradually until the pressure reaches a comfortable level.
The NK30 can be used during activities where knee support is needed, including walking, hiking, and everyday activities.
An appropriate wearing time may vary depending on the user's condition and activity environment, so it is advisable to follow the wearing instructions provided in the product user manual.
If numbness, excessive pressure, skin discomfort, or other discomfort occurs while wearing the product, adjust the amount of air or fixation level, or temporarily remove the product.
The NK30 can be used during activities involving repeated knee movement, including walking, hiking, and trekking.
When using it for the first time, it is advisable to begin with a short wearing period and adjust the amount of air and fixation level according to your activity and comfort.
People who want broader support not only around the center of the knee but also the surrounding areas,
those who prefer a longer knee support rather than a short-type product,
those who want a product that allows them to directly adjust the amount of air,
and those who want knee-area support during everyday activities such as walking or hiking
may find the structural features of the NK30 worth considering.
