Inov-8 Women's Size Chart

We know that finding the right shoe size can be tricky!

We’d recommend looking at the size guide below which shows the approximate length of each size’s insole in centimetres.

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.

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, we’d recommend having at least 1.5cm of extra space beyond the end of the longest toe to ensure comfort.

We have graded the fit of all our shoes from 1 to 5 to make it easy for you to find the perfect fitting shoe. All our 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 narrowest fit. At the other end of the scale, Grade 5 has the widest fitting toe box.

As a rough guide, Grade 1 represents an industry B fit, while Grade 5 equates to a 2E fit in the forefoot.
