As earlier mentioned, the primary factor that causes the difference in footwear sizes from brand to brand is the Shoe Last. As brands continue to use different lasts and don’t follow the same standards, there will always be a difference in shoe sizes. The primary purpose of lasts in the footwear industry is to help give shape to shoes.
Many brands have different requirements that they use when it comes to manufacturing their shoe lasts. First, they consider the type of shoes and what they are to accomplish. For instance, the shoe last utilized for running shoes is different from those used for leisure shoes.
Apart from that, they also have different standards that they often embrace. For example, one brand might decide to go for lasts with a broader toe box for their shoes. A shoe last plays a significant role in the uniqueness of every footwear brand
Apart from brand to brand, shoe sizes can also differ a bit from shoes to shoes for a single brand. The cause of that often depends on the factories where the shoes are produced. In case you don’t know, shoe lasts can vary slightly from factory to factory. And since that’s the case, you may also expect shoe sizes to vary slightly.
Will one US shoe size make a difference?
The answer to that question is yes, it can make a difference. The difference between a whole US size is typically 0.3 to 0.4 inches. The difference between half a US size is around 0.15 to 0.2 inches. So even if you think that 0.4 inches isn’t a big difference it can have a big impact, especially if you are wearing a shoe that is 0.4 inches too small.
Why Can’t All Shoe Sizes Have The Same Sizing?
As earlier mentioned, shoe sizes differ from brand to brand because of the shoe lasts used by each of them. However, it’s worth knowing that that’s not the only factor influencing the difference in footwear sizes.
Another factor that also influences why shoe sizes differ from brand to brand is our feet. How do I mean?
There’s no denying that every shoe brand uses different shoe lasts – one of the factors that define their uniqueness. As we all know, shoes are mostly mass-produced by big brands in their various factories across the world. What that means is that a generic last is what these brands uses to shape and size the shoes.
