Footwear fitting is the process of selecting and trying on shoes to ensure they properly fit the wearer's feet. This involves measuring the length and width of the feet, as well as considering factors like arch support and toe space. Proper fitting helps prevent discomfort and foot problems, such as blisters or bunions. When fitting footwear, it's important to try on shoes at the end of the day when feet are slightly swollen. This ensures a more accurate fit. Additionally, different brands and styles may vary in size, so it's essential to check the fit of each pair, even if they are the same size from different manufacturers like Nike or Adidas.
