How to Choose the Right Size Winter Boots for Your Kids

Once that first snowfall hits, sizes disappear fast in our winter boot collection,  so don’t wait until the cold sets in. Shopping early gives you the best selection and helps ensure your child gets the right size, fit, and warmth for the season ahead. If you're a local customer we will accept exchanges on unused winter boots within a reasonable time. 

Here’s how to find the perfect fit for your child this winter.

Step 1: Measure Their Feet

Before you even look at a size chart, start with actual foot measurements. It’s the single most accurate way to find your child’s size. With every brand doing things a little different, we have been focusing on getting the measurement instead of a shoe size. 

Here’s how to do it at home:

1. Have your child stand up,  you want their full body weight showing their true foot length.
   

2. Place a piece of paper under their feet and trace both feet.
   

3. Measure from heel to longest toe, and across the widest part for width.
   

4. Record the length in centimetres (cm) or millimetres (mm);  these are the numbers that matter most.
   

Pro Tip: Bring your foot tracing when you visit us in-store! We can compare it directly to the insoles of boots on the floor.

Step 2 Allow Room for Growth & Circulation

Children’s feet grow quickly — sometimes a full size within a season!
A good rule is to have extra room. One thing we find is most people are wearing too small shoes. And a small shoe is a cold foot. 

• Leave a thumb’s width (about ½ inch) of space between the longest toe and the front of the boot.
  

• Leave at least ¼ inch for circulation. Snug boots can make feet colder by restricting blood flow.
  

And remember: sometimes it’s better to wait a few weeks if a growth spurt is clearly around the corner. Ya, I know that boots sell out - but this quick and fast growth is most common in kids under 3. It can sometimes happen to your bigger kids too, but less so. 

Step 3: Consider Socks & Layers

Think about the type of socks your child will wear in their boots.

• Thicker socks (especially some styles of wool) need more room.
  

• Some kids do better with thin merino wool socks that regulate temperature and wick moisture.  keeping feet warm without bulk.
  

Step 4: Try On & Test the Fit

When trying on winter boots:

• Use the same socks they’ll wear in winter.
  

• Check for snug fit at the heel and wiggle room at the toes.
  

• Have your child walk and run! Watch for rubbing, slipping, or tripping.
  

If they stumble or the heel lifts too much, size or style may need adjusting. We do find that many kids can handle a larger boot with ease. Check out this blog post about why soft soled winter boots might be a better choice for your early walkers.

Step 5:  Consider an Ankle Boot

One thing we’ve noticed over the years is the growing demand for tall winter boots, especially in snowy climates like Prince George. But the truth is that tall boots aren’t always necessary, and low key the worst. 

For many kids, an ankle-height winter boot actually provides better flexibility and mobility.

• They fit more easily under snowsuits, reducing bulk.
  

• They’re often lighter, making them easier for kids to walk, run, and climb in.
  

• And with the right waterproofing and insulation, they can perform just as well in most winter conditions.
  

If your child spends more time on playgrounds and sidewalks than deep snowbanks, an ankle boot might be the smarter (and comfier) choice this winter. They area a fantastic choice for running around doing errands and much easier to keep on. 

Final Thoughts

Getting the right size winter boot isn’t just about numbers. it’s about comfort, warmth, and freedom to explore.

By measuring your child’s feet, focusing on EU or cm sizing, and checking for waterproof, adjustable designs, you’ll find the perfect fit that lasts all season.
