For most NEENCA knee sleeves, measure your thigh circumference at the point shown in the product size guide. If you are between two sizes, choose the smaller size for firmer compression or the larger size for a more relaxed fit.

It should feel snug, secure, and supportive without sharp pinching or excessive tightness. Light pressure from compression is normal, but the brace should not interfere with normal circulation or cause persistent numbness, tingling, or discomfort.

If the brace slides, rolls, pinches, or feels restrictive, please check your size and fit.

Material composition varies by product and model. NEENCA products may include nylon, spandex, elastic fibers, silicone, gel pads, spring stabilizers, straps, or other support components depending on the item.

Please check the material details on the specific product page before ordering.

NEENCA products are designed and tested  in the United States, and manufactured through controlled production processes. Manufacturing location may vary by product, but many products are produced in China under NEENCA quality standards.

NEENCA braces are designed to provide compression, stability, and support during movement. Many customers use them for everyday activities, workouts, walking, standing, and recovery support after physical activity.

NEENCA products are not a substitute for medical diagnosis or treatment. If you have an injury, medical condition, severe pain, or ongoing symptoms, please consult a qualified healthcare professional.

Customers commonly wear NEENCA knee braces during walking, work, exercise, sports, travel, or daily activities when extra support and stability are desired.

If you are using a brace after an injury, surgery, or for a diagnosed condition, follow the guidance of your healthcare professional.

Many NEENCA products are designed for active movement, including walking, running, gym training, basketball, hiking, and other sports. Choose the model and size that match your activity level and preferred support feel.

Stop use if the brace causes discomfort, unusual pressure, numbness, or irritation.

We do not recommend wearing a compression brace while sleeping unless instructed by a healthcare professional. Compression products are generally intended for active use, daily movement, or short rest periods while awake.

If you need overnight support because of an injury or medical condition, please ask your healthcare provider which type of brace is appropriate.

Temporary light pressure marks can happen with compression products and usually fade shortly after removal. However, persistent deep marks, numbness, tingling, rash, or discomfort may indicate that the brace is too tight or not the right fit.

If irritation continues, stop using the product and contact us or a healthcare professional.

For the most secure fit, most knee sleeves and compression braces should be worn directly against the skin or over very thin clothing. Wearing a brace over thick pants may reduce grip, compression, and stability.

Hand washing is recommended to protect elasticity and support components. Wash with cold or lukewarm water and mild detergent, then air dry naturally.

• Do not bleach
• Do not iron
• Do not dry clean
• Do not tumble dry

Lifespan depends on usage frequency, activity level, care, and washing habits. With proper care, many braces can last several months or longer.

If the brace starts slipping, loses elasticity, no longer feels supportive, or shows visible wear, it may be time to replace it.

Most orders are processed within 1–3 business days. Processing may take longer during holidays, sales events, or periods of high order volume.
