Oura Ring Sizing

Here's what to expect.

Step 01

Once you place your order, you’ll receive your free sizing kit as soon as one is available, usually 1-2 working days.

Step 02

Try a sample ring on your preferred finger to gauge comfort. We recommend wearing your Oura Ring on your index finger for optimal performance and accuracy. However, any finger except the thumb will work.

Step 03

Order your ring in the desired size and style by using the online ordering.

Step 04

Return your fitting kit in the courier pack supplied with order and on receipt we will refund the fitting kit fee (less shipping).

After a style or size we don't have? 

Let us know, and we can order styles and sizes individually as part of our next stock intake. Please be aware that we only receive new Oura stock every six to eight weeks so unstocked rings may take a long time to arrive in clinic. 

Warranty and returns

Oura rings are covered by a two year manufacturer's warranty. This warranty covers pre existing defects in materials and failure to operate in expected capacity.

Please be sure you are happy with your size before purchase. We have free sizing kits available so you can be certain you have the right fit.  We are unable to accept change of mind or do size swaps once the rings packaging has been opened.

Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too. Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.

Quality No Show Socks That Are Comfortable and Durable
Size: Large, Color: (100) White / White / Black
These Under Armour no show socks are great for everyday training and casual wear. The cotton blend feels comfortable and they stay in place throughout the day. Getting six pairs in a pack is solid value for a quality brand. They hold up well after multiple washes and the no show style works great with most athletic shoes. A reliable go-to sock.

Comfortable
Size: Large, Color: (001) Black / Black / White
I recently picked up a pair of Under Armour socks, and they’ve quickly become my go-to choice for daily wear and workouts. From the first wear, the fit felt snug and supportive without being too tight. The fabric is lightweight yet durable, and it does a great job wicking sweat — keeping my feet dry even during longer runs or intense gym sessions. One of the things I appreciate most is the arch support and cushioning in the right places. It adds just enough padding where I need it, especially under the ball and heel of the foot, which makes a noticeable difference on days when I’m on my feet a lot. The socks also have a nice breathable mesh pattern that improves airflow.
