Shoe Fit Scale

inov-8 have graded the fit of all their shoes from 1 to 5 to make it easy for you to find the perfect fitting shoe. All inov-8 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 the closest, most precise fit. Grade 5 has the widest fitting toe box.

inov-8 has meticulously studied the foot and its function during the gait cycle and also the interaction between the foot and the terrain. They have used this knowledge to develop their fitting scale. For technical footwear a good fit is essential to enhance your performance.

The lower the number on the scale, the narrower the fit, which ensures minimal internal movement of the foot when running fast on technical terrain. Shoes with the higher numbers on the scale will suit athletes with a wider foot and those wanting that extra comfort in the toe box. This wider toe box allows the toes to splay for increased stability when lifting heavy weights. It’s also perfect for longer runs and races when toes begin to swell.

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