What's My Size?

We want your Daysides to feel just right from day one — so we’ve created a simple, no-stress guide to help you find your ideal size. All you need is a tape measure, a chair, and (optionally) a helping hand.

Step 1:

Sit comfortably with your knees at a 90-degree angle.

Step 2:

Measure around the widest part of your calf — it’s easiest with someone’s help.

Step 3:

Have your shoe size nearby.

Step 4:

Use the chart below to match your measurements to your ideal sock size.

That’s it — comfort, measured just for you.

⚠️ PLEASE NOTE: always choose your size based on your calf circumference. The shoe size is only a guideline for foot length.

Not sure about your calf size? No worries, we offer a 100-day guarantee so you can try our socks at home and find the perfect size!

If you're between sizes, we recommend sizing up or email support@mydayside.com
