Frequently Asked Questions (NK30)
Q1. How do I select the NK30 size?
For the NK30, please check the center of the knee circumference first, but,
It is important to make sure to also consider the circumference of the lower thigh and upper calf when selecting.
The NK30 is a long type that is longer than the NK10 and has a structure that wraps around down to the lower thighs.
There are quite a few people who have said that they chose based only on knee circumference and found it uncomfortable because the thighs were too tight.
“I ordered a size S for a gift, looking only at the knee circumference, but
There is also someone who said, ”The thigh and upper calf areas were too tight, so I exchanged it for size M.”.
In addition to the knee circumference standard, up to the lower thigh and upper calf
We recommend selecting based on the circumference.
The detailed dimensions of the entire product are listed at the bottom of the product detail page.
Please make sure to check before selecting.
Q2. If the size is on the borderline, which size should I choose?
If the size hits the boundary range
It is safer to choose a larger size based on your thigh thickness first.
Because the NK30 has a structure that wraps not only the knees but also the lower thighs,
Even if a smaller size fits based on knee circumference
If your thighs are on the thicker side, it may be difficult to wear.
The compression strength can be adjusted using the amount of air injected and the strap.,
Even if you choose a slightly looser size, you can increase the aero fit.
Conversely, a size that is too small may constrict the thighs or make it difficult to wear, so,
If it hits the boundary, please prioritize the larger one.
Q3. What is the difference between NK30 and NK10?
Both products are inflatable medical knee braces, but,
There are differences in range of support and activity.
The NK30 is a long type that covers widely up to the knees.
Supports the lower thigh and upper calf together
It is suitable for those who need greater overall knee stability.
Like degenerative arthritis, cartilage damage, ligament injury, and post-surgery rehabilitation
In cases where overall support is needed due to poor knee condition,
If you want wider and stronger support than the NK10, the NK30 is the right choice.
“Some people have also mentioned that "the longer product seems to provide better support than the short one.".
The NK10 is a short type that provides intensive support only to the center of the knee.
It is short, allowing for free movement during activities,
It is not very noticeable even when worn under long pants.
It is suitable for those who want to hike, exercise, and go about their daily lives while lightly protecting their knees.
There are many people who try the NK10 first, are satisfied, and then purchase the NK30 as an additional unit.
NK10 for daily activities and light exercise, or if knee condition is worse or
When overall support is needed, it is also a good idea to differentiate and utilize NK30.
Q4. Does the NK30 come as a single side only, or as a set for both?
The NK30 is a single-piece unit based on one side.
If you want to wear them on both knees, you must purchase 2 separately.
In the reviews, there was also a comment saying, “I tried one side and liked it so I ordered another one.”,
“Many people have told me that they purchased additional ones to wear on both sides.
Please be sure to check the product composition before purchasing and order the required quantity.
Q5. How do I release the air after inflating it?
Lightly press the button in the center of the air inlet to release the internal air.
Many people have told me that it is easy to operate, requiring only a light touch with a finger.
To inflate, simply connect the enclosed hand pump to the valve and press it a few times.,
You can disconnect the pump once the desired compression intensity is reached. If the compression feels too strong...
Please gently press the inflation button to release air little by little and adjust to the intensity that suits you.
When using it for the first time, you can quickly learn how to use it by referring to the enclosed instruction manual.
Q6. Can I wear it all day? Can I wear it while sleeping?
There is no separate time limit for wearing, so you can wear it freely for as long as needed during hiking, exercise, or daily walking.
There are many people who wear it all day long.
However, wearing it while sleeping is not recommended.
During sleep, changes in posture can cause excessive pressure or strain on blood circulation, and,
It is difficult for you to perceive the pressure. Wear it while active during the day,
It is recommended to remove it before going to bed. Since you can directly adjust the compression strength by controlling the amount of air injected,
If you feel numbness or discomfort while wearing it, please release some air or loosen the strap.
Q7. Can I use it for hiking, walking, or exercising?
The NK30 is the most widely used product by people who need knee support during hiking, walking, and daily activities.
In particular, many people have told us that the strain on their knees has been significantly reduced when going up and down stairs and descending.
“There are also people who have shared their experiences, saying, ”Going up and down stairs became much easier because the air pressure supported my knees,“ and ”I felt less knee pain even after hiking.”.
Many people wear them in their daily lives, even while exercising such as weightlifting, squatting, badminton, tennis, and golf.
However, if you have severe knee pain or are in the middle of rehabilitation after surgery, it is recommended that you start with light walking and gradually adapt rather than engaging in strenuous exercise.
When first wearing it, it is recommended to start with short activities and gradually increase the wearing time according to the condition of your knee.
