At Piggy’s, we believe baby socks should actually stay on—without squeezing, slipping, or leaving marks. That’s why we created a thoughtfully designed sizing system to support every stage of your baby’s first steps (and wiggles).

Size matters, so getting the correct size for your baby's feet will ensure the socks stay securely and comfortably in place all day.

Place your baby’s foot flat on a piece of paper.

Gently mark the heel and the tip of the big toe.

Measure the distance in inches.

Match to our size chart above!

Babies grow fast—and so do their feet. A perfect fit ensures comfort, healthy development, and socks that actually stay on.
