Size Guide

Ten Little shoes are designed with a wide, foot-shaped toe box and flexible zero-drop soles to support healthy foot development. Because our shoes mimic the natural shape of a child’s foot, they may fit differently from mass-market brands. Use the charts and fit tips below to find the right size.

The Ten Little Fit Philosophy

Foot-Shaped Toe Box

Wide, natural toe box gives little toes room to splay and wiggle, supporting healthy development.

Natural Shape

Zero Drop & Flexible

Flat, flexible soles provide optimal ground feedback and encourage a natural gait.

Barefoot Friendly

Adjustable Fit

Hook-and-loop velcro straps secure the foot and accommodate a variety of foot shapes, wide or narrow.

Customizable

How to Measure & Verify Fit

Measure the Foot

Stand on a piece of paper with heel against a wall. Mark the longest toe and measure from wall to mark. Use the longer foot.

Match to Chart

Find the foot length in the shoe chart above. If between sizes, size up for growing room and comfort.

Check the Cheetah Insole

Remove the cheetah-print insole and have your child stand on it. If the longest toe lands within the cheetah line, the fit is correct.

Size Up When Needed

If toes extend past the cheetah line, it’s time to size up. Save the shoebox—it has a built-in size guide inside.

Fit Note: Ten Little shoes are not offered in multiple widths. Instead, the foot-shaped design and adjustable velcro straps accommodate a range of foot shapes, including wide and narrow feet.

2 out of 3 kids are wearing the wrong shoe size. Wearing shoes that are too small or too big can impact foot development. Always verify fit using the removable cheetah insoles.

For the three styles without half sizes (Splash Sandals, Rain Boots, and Snow Boots), size up if your child is between sizes.

If you have questions about sizing, contact the customer support team for personalized help.
