Does GS Stand for in Shoes

Nike is a well-known and loved brand for athletic and casual footwear. The company also has a large selection of kid’s shoes. Here’s how it recommends that you measure your child’s feet:

What you need:

  • A ruler.
  • Wall.
  • Flat surface.
  • Pen and paper.

Here’s what you do:

  1. Have your child stand on a flat surface with their back against a wall. Align their heel with the wall.
  2. Place the ruler on the inside of the feet and measure from the wall to the longest toe. Then write down the results.
  3. Go to Nike’s sizing tool and enter the measurements, this will recommend what size to get.


Pro Tips

  • Measure your child’s feet in the afternoon, even babies. Feet tend to swell slightly toward the end of the day, which is essential to take into consideration.
  • Ask your child to put on a pair of regular socks that they’d usually be wearing. They shouldn’t be too thick or too thin.
  • When your child is trying the shoes, allow for 5-inch from the longest toe to the front of the shoe.
  • Once the shoes are on, encourage them to walk and do some slight jogging on the spot to ensure the size is right. Of course, this only applies to little ones who are able—toddling age and upwards.
