It should be noted, however, that not all Inov8 shoes are going to follow this sizing scheme strictly. Even the brand itself leaves sizing recommendations for some models: "We recommend going half a size down for this shoe."

Upper design and materials are also likely to affect the shoe's fit. That's why we pay close attention to the fit and sizing peculiarities of each Inov8 shoe in our lab. This includes measuring their internal length as well as toebox dimensions. Have a look at our in-depth lab reviews for more information.

Inov8 fit options: Precision, Standard, and Wide 

Inov8 releases some of its shoes in several width options - from the more snug-fitting Precision Fit to the more accommodating Wide Fit.

According to the brand's width chart, there is a 5 mm difference between these width options. Measuring the widest area of your forefoot will help you determine whether you need a Standard Fit or opt for alternative widths. The width chart below will help you:
