Feel the terrain, fly over asphalt
Tempo is built for fast movement across mixed terrain. A responsive road-to-trail shoe for hard training days and all-surface racing, where efficiency and grip need to work together. Part of the Fuzion collection, it blends the immediacy of a road shoe with trail-ready stability, so you can leave the tarmac without thinking twice.
Underfoot, an extremely light rubber outsole with 3 mm lugs keep you performing off-road while preserving feel and durability on asphalt. The all-new cushioning comes from our most advanced nitrogen-infused supercritical foam yet, the SuperFOAMance+, which provides even more bounce and energy return needed for those fast races in mixed terrain.
Embedded inside the midsole is a full-length branched rock plate. Common in trail shoes, it adds torsional stability and reduces energy loss, sharpening each stride while protecting from rough terrain. The lightweight engineered mesh upper drains quickly and stays breathable, while a soft anti-slip heel and VJ Fitlock system hold the foot steady when things get technical.
When you want to feel the terrain and fly over asphalt, choose Tempo.
Tempo fits most people true-to-size.

- Place a sheet of paper on the floor and against a wall.
- Make sure that you are wearing the same socks as you would typically wear with these kinds of shoes.
- Wearing these socks, stand on the sheet of paper with your foot perpendicular to the wall and your heel against the wall.
- Then ask your friend to draw a line just in front of the longest point of your foot. Repeat with both feet and take the longer distance to determine your size.
- Use a ruler and measure the distance between the wall and the line that you drew to find your size. If you are between sizes, choose the bigger one.
The sizes on the table are racing fit with just a couple millimeters of free space on the toebox. If you prefer more space, go for the bigger size. If you have questions or need help with sizing please contact info@all4o.com, we are happy to help.
