Size Guide


If you already have a hiking boot, running shoe, or training shoe that fits you well, you could measure the length of the shoe’s insole and match this with the size guide below.

Alternatively, you can measure the length of your foot and add between 1 and 2cm to find the correct insole length. It is hard to be exact here, as sizing is so personal – but in hiking boots, running shoes or training shoes, Inov-8 recommend having at least 1cm of extra space beyond the end of the longest toe to ensure comfort.

Depending on the type of activity you’re doing you may wish to go for a more precision fit (for racing for example). Equally you might prefer a wider fit if you are running longer distances or lifting heavy weights.


Make sure you’ve measured the length of your foot first. You’ll need this measurement to work out the correct width.

  • On a hard floor, put a piece of paper against a wall.
  • Stand on the paper in your socks. Wear the type of socks you’d normally wear with this type of shoe.
  • Make sure the back of your heel is against the wall and that you’re placing your weight on your foot.
  • Ask someone to trace a line around your foot.
  • Make a mark either side of your foot, at the widest point.
  • Measure the distance between the marks using the width chart below.
  • It’s common for feet to be different widths, so make sure you measure both.
    You should choose your width based on the measurement from your wider foot.

Inov-8 grades the fit of all their shoes from 1 to 5 to make it easier to find the perfect fitting shoe. All shoes are designed with Met-Cradle technology to lock down the mid-foot for a stable hold. Where they differ is in the toe box. Grade 1 represents our closest, most precise fit. At the other end of the scale, Grade 5 has the widest fitting toe box.
