Right size guarantee


Hai sizing is somewhat roomier compared to walking shoes and contains room for a woolen sock. Adults’ shoes should have a toe allowance of minimum 5 mm, because toes move forward when walking. In addition to this 5mm toe allowance, kids’ boots should have 5-10 mm room for growth when new (total 10-15 mm).

The best way to make sure that the boots are not too small is to step on a piece of paper and draw your feet. Then measure the length of the foot and add toe allowance minimum 5mm to the measurement and compare it to our size chart. The best time for measuring the foot is in the evening, because feet tend to get swollen and widen during the day. It’s worth measuring both feet because they are rarely exactly the same size.

Here are some more tips per style so that the size choosing will be easier

Hai

This style is quite roomy and it contains room for woolen sock.  The best way to make sure that the boots are not too small is to step on a piece of paper and draw your feet and measure the length of the foot then add toe allowance minimum 5mm to the measurement and compare it to our size chart.

The more important measurement is the length! Our boots are quite wide so do not worry about the width measurement.

Hai Low

The ankle length boot is a bit more fitted than Hai. The Hai Low design is slim and sleek for city use. The fit is quite snug so that the boot will stay on the foot better. With Hai Low we recommend that you choose your size according to your normal shoe size. But again, drawing and measuring your feet and adding the toe allowance will give you the best knowledge to make the best decision.

The more important measurement is the length! Our boots are quite wide so do not worry about the width measurement.

Hai Kids

Children’s feet grow at an astonishing rate. Many parents have a hard time choosing shoes and rubber boots for their offspring, because children’s feet grow in spurts. Kids’ feet grow at different speeds at different ages: a toddler’s foot will grow 2–3 sizes in growth spurts during one year; 3–6-year-olds’ 2 sizes and school aged kids about 1–2 sizes during one year.

This style is quite roomy and it contains room for woolen sock. The best way to make sure that the boots are not too small is to draw your kids’ feet on a paper and measure the length of the foot then add toe allowance minimum 5mm to the measurement and compare it to our size chart. Children’s feet should be measured upon buying new rubber boots and also when seasons change. This way you can make sure that the child’s boot is the right size and doesn’t pinch the toes. Kids themselves rarely notice that their shoes have become too small. 

The more important measurement is the length! Our boots are quite wide so do not worry about the width measurement.
