Searching for the perfect shoe size is the first thing to do while buying shoes online. You simply cannot get your ideal size even when they are Nike or Adidas shoes. It's good that both of these brands offer a good refund and return policy, so you can at least return it once you order the wrong size.

  • If you already have Adidas or Nike shoes, check for their size if they fit well. It can be on the Heel.
  • However, if you are a new buyer, first, measure your shoe size. Take a measuring tape and start measuring your foot by the end of your Heel to the thumb or the longest finger of your foot.
