Some notes on New Balance shoe sizing
New Balance follows a slightly different shoe size conversion than most of the other brands.
Besides Hoka, New Balance is the only other shoe brand in the United states to feature a half size conversion between UK and US sizes. adidas follows the same sizing convention too for US and UK sizing, but differs when it comes to EU and CM sizes.
If you look at the sizing chart of other major sports footwear brands like Nike, Reebok and Underarmour, they feature a US-UK conversion difference of one. Confused? Let us explain with a few examples.
A US size 10 in Nike is UK size 9.
A US size 10 in Reebok is also UK size 9.
But when it comes to New Balance, a US size 10 converts into UK 9.5. Naturally, all this can be confusing when switching across brands.
