Things To Remember To Get Perfect Fit Of Adidas Or Nike

Only taking the exact measurement of your feet may not give you a perfect fit. There are other pieces of stuff that you need to keep in mind.

  • Wear socks with your shoes. Wearing thick socks with your shoes ensures a proper fit. For example- if you feel your shoe is a bit loose, wearing socks will occupy the extra space giving you tight-fitting.
  • Insert insoles inside your shoes. Insoles hold the feet in the exact place in the boots, support the arches, reduces foot pain if you have any.
  • Due to walking, our feet swell up throughout the day, and at night, our feet are the largest. The best time to take foot measurement is in the afternoon. At that particular time, you get the correct size of your feet.
  • Every time you buy new shoes, take new measurements of your feet. Don’t use the previous size because our feet’ ligaments and tendons tend to loosen a bit over time, resulting longer and wider feet. Also, sickness or pregnancy changes our feet length.
  • Don’t try to guess your feet size; always measure your feet length following the methods I have mentioned earlier. Assuming your feet size will end you up with the wrong size shoes. And returning them is a hassle, right?
  • Your heel should not slide out of the shoes or feel too tight. If that happens, you have got the wrong size. And wrong size shoes can make your feet swell up or increase the chance of falling.
  • If you are purchasing shoes in person, wear the shoes and run, walk or jump to check whether you are comfortable in it or not.
