Pop Quiz: What’s your kid’s shoe size? Don’t worry, most of us failed that one! Children’s feet grow extremely quickly, and busy parents have a hard time keeping up. That’s where SpeedSmith’s app can help. With this app, you can get a suggested shoe size within seconds, and you can be notified before your child will need to size up.

Easy, just grab a sheet of paper

Measures in seconds

Speedy and easy shopping

Measure your kid’s foot for a suggested shoe size

You’ll need a piece of paper, a hard floor, a wall, and don’t forget your kid! 😂 We know that kids are ok with standing still for a super long time (not), and we’ve written fancy and patent-pending code that helps measure as quickly and accurately as possible.

Know before your child will need to size up

We know how speedy kids feet can grow, 🚀 so speedy that sometimes there’s a toe poking through before you know it. Just because your kids don’t say anything, doesn’t mean their shoes are still the right size. Our app can notify you when it’s time to measure again.

Unique profiles for everyone in the family

Our app can keep track of multiple kids’ feet and sizes, tracking over time and based on previous measurements. Oh, and you might want to measure your own feet too. 😜

Measure and track both Left and Right feet

Believe it or not, most of us have different sized feet. Our app is smart enough to keep track of that. If your kid needs different sizes for left and right, contact us and you can be a part of our ZigZag ordering program.

Shop our limited edition shoe drops with confidence

Your suggested shoe size automatically transfers to the shop on our app, where you can check out our super fly and super comfy kids kicks.
