  • A lot of people have one foot larger than the other so before buying a new pair of shoes, consider this aspect
  • The shape of shoes is very important to consider. If you are purchasing the shoes that doesn’t match the shape of your feet, you’ll feel the discomfort and adverse results
  • A lot of people buy tight shoes and expect the shoes to stretch after certain uses. Don’t do this as it can hurt your feet badly
  • To identify if the shoes fit best, consider how your foot slips in the shoe. The shoe should not ride up or down too much when you walk
  • Before buying the shoes, walk in the shoes to make sure that it’s a good fit
  • Choose the shoes made using soft and breathable fabric. Tight and hard materials will hurt your feet badly
  • Wear the socks you are going to wear with the new pair of shoes while trying the shoes

  • Examine the soles. Make sure that the soles are sturdy and irritation free

Difficulties in shoe size conversions

Although there are ample of shoe size convertors, there are certain issues that people might face. Here’s what makes the convertors not 100% accurate.

  • The shoe conversion systems are not fully standardized. The shoe sizes might differ slightly as per different manufacturers. The manufacturers in US make shoes differently than the manufacturers in UK and thus, though they are using the same continental European system for making shoes, there might be a slight difference in terms of shoe size and fitting.
  • The biggest issue with children shoes is that children shoes are always calculated in a different way. The growth speed of children is extremely different. The fast growing kid might need bigger shoes than the other kid who grows slowly. Rather than considering the conversion charts, it’s better to measure the size manually
  • People only consider foot length while measuring and purchasing the shoes. Some people have broad feet while some have narrow and thus, it is important to measure the width of feet before purchasing the shoes. For wider feet, sometimes, large sizes are required
