Perfect balance

A new version of the Ra specifically adapted to the anatomy of the female foot. The Ra is a versatile shoe created to achieve a perfect balance between ultimate responsiveness and maximum transfer of power from the toes when standing on tiny footholds. The RA’s beautifully simple and uncluttered design is not only spectacularly effective in all forms of climbing but also supremely comfortable, making climbing feel easier and more intuitive.

inov-8 Shoe Size Guide

Shoe Fit Scale

Fits Narrow12345Fits Wide

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.

Power, Precision, Balance

Constructed on a 4mm rubber outer sole and a five-layer insole, the RA is rigid enough for tiny edges while providing sufficient flexibility and responsiveness for the most tenuous of smears

Sticky rubber reinforcement

The RA features sticky rubber reinforcements to both the forefoot and instep, which not only increases abrasion resistance, but also adds structure and support in these areas of the shoe. Together with the RA’s asymmetric shape and glove-like fit, this allows for greater precision on tiny edges.

Closer to the rock

Every aspect of the Ra’s design enables greater precision and usability. Its bellows tongue facilitates rapid fitting and removal.
