Inov-8 men's and women's size chart

As a more running-oriented brand, Inov-8’s shoe sizing scheme tends to correspond to that of most running shoes.

However, half-a-size to full-size discrepancies still occur, depending on the brand. That’s why it’s better to know your exact foot length up to 1-mm accuracy to ensure the right Inov-8 size for you.

Inov-8 fit scale

According to the brand’s official website, the fit of all Inov-8 shoes is designed snug in the heel and midfoot but varies in the toebox: from narrow profiles to extra wide ones.

Narrow Slightly narrow Medium Wide Extra Wide
1 2 3 4 5

Narrower fit is used on trail shoe models that are meant for technical rocky and muddy terrain and faster paces. That’s where you need the highest level of lockdown to prevent any excessive foot movement inside the shoe and stay in control. Examples: Mudclaw and X-Talon.

Wider fit can be found on shoes for long-distance and ultra-running as feet swell after miles. Example: Terraultra. It is also used in cross-trainers and lifting shoes, where the ability to splay toes affects stability and control.

If you don’t have a chance to measure the feet right now, find a shoe from another brand that fits you well. Use the conversion tool below to find out its equivalent in Inov-8:
