Comparing Nike and Under Amour’s shoe sizes

How different is Nike’s sizing chart from Under Armour’s?

Does Under Armour run big or small?

A size 10 for example in one brand might not correspond to the exact same size 10 in another brand.

But, that said…

They actually do.

Under Armour and Nike’s sizing are actually very similar to each other.

The only thing you need to remember is that UA does all sizing true fit and most people find it a bit on the snug side.

I heard stories from online shoppers telling that buying tennis or running shoes, or even casual trainers online from Nike, Under Armour, (or just any other brand really) means ordering three pairs in different sizes, for example, ordering the 8, 8.5 and 9, and then returning the ones that don’t fit.

Nike vs Under Armour Sizing

How to find the sizing difference between Nike and Under Armour tennis shoes?

  1.  The first step is to grab a pair of shoes that you already own, either from Nike or Under Armour. If you don’t own any of those, trace very, very closely your entire foot on one piece of paper and then measure the drawing from heel to toe. Take note of the measurement in centimeters or CM.
  2. Locate the tag with sizing information underneath the tongue of one of the shoes. Look for the size in cm.
  3. Using the centimeter information as a reference, find the corresponding size for Nike and Under Armour in the table below. Easy!

(oh… and let me know in the comments below if it worked for you)

 

The exception to this rule is if you’re buying a model of shoes that have a thinner upper material composition and tongue. If that’s the kind of trainers you are buying, lookup for a size 0.50 cm smaller.
