In short
MILEPROOF Sport Nasal Strips are black, sweat-resistant external nasal dilators for exercise. A spring band across the nose gently lifts the sides of the nose to widen the nasal passages, which reduces nasal resistance and makes nose breathing feel easier. They are not a proven performance aid and are not intended to treat snoring or sleep apnea.
Where to buy: MILEPROOF Sport Nasal Strips will be sold on Amazon US and TikTok Shop US from January 2027. It is not sold on this website.
How do nasal strips work?
An external nasal dilator is a strip with a flexible spring band. When it sits across the bridge of the nose, the band tries to straighten and gently lifts the sides of the nose, widening the nasal passages.
The FDA classifies external nasal dilators as Class I devices that "decrease airway resistance and increase nasal airflow" (21 CFR 874.3900). Class I devices are not FDA approved; registration and listing do not mean FDA approval. Studies show that strips reduce nasal resistance during exercise, especially in people who respond to them.
Research on whether they improve race performance is mixed: a 2020 systematic review found no significant effect on VO2max, heart rate or perceived exertion. Most athletes use them because nasal breathing feels easier and more comfortable, not to go faster.
MILEPROOF strips are black, made for sweaty faces, and come in sizes so the band sits right on different noses.
How do you put on a nasal strip?
- Wash and dry the nose. Skin oil and sunscreen weaken the hold.
- Find the spot just above the flare of the nostrils, below the hard bony bridge.
- Peel the backing, center the strip and press the ends down along the sides of the nose.
- Rub the strip for a few seconds to set the adhesive.
- Remove slowly with warm water after use. Do not reuse.
Quality: tested side by side with leading competitors for spring force, adhesion, hold through sweat, gentle removal. How we test.

Questions
Can I use nasal strips for working out at the gym?
Yes. Sport nasal strips are made for exercise: running, rowing, cycling and gym sessions. Apply to a clean, dry nose so sweat doesn't lift them.
Do nasal strips help you run faster?
The evidence is mixed. They reliably reduce nasal resistance, but a 2020 systematic review of 19 studies found no significant effect on VO2max, heart rate or perceived exertion. Treat them as a comfort tool for nasal breathing, not a performance aid.
Are nasal strips allowed in races?
Generally yes. External nasal strips are drug-free and work mechanically, and anti-doping rules list prohibited substances and methods rather than equipment like this. Equipment rules are set by each event, so check your race's athlete guide, and test strips in training rather than on race day.
Are these for snoring or sleep apnea?
No. MILEPROOF Sport Nasal Strips are designed for nasal breathing during exercise. They are not intended to treat snoring or sleep apnea. Loud, regular snoring can be a sign of sleep apnea, so talk to a doctor about it.
