  • 97 / 100 | Road Trail Run

    The Sonic RA Max is a light for its substance daily trainer which does not skimp on support, stability, and outsole rubber. No frills, just a scientifically grounded masterpiece of functional design leading to a clear new contender in the daily trainer category.

  • 91 / 100 | Runner's World

    The Sonic fits like a warm hug. Testers specifically gushed over this new version’s comfort: the collar and tongue are both wrapped in memory foam for a great step-in experience, and “zero chance of blisters” according to one tester.

  • 93 / 100 | Road Trail Run

    My first run in the Sonic RA Max was joyful! The magic balance of just enough cushion, while still feeling in touch with the road is just what I was hoping for. These shoes feel plenty light and the mesh upper has been surprisingly fine with Merino socks even at temps below zero, I can't wait 'til spring!

Updates to Salomon Sonic RA Max

  • The Salomon Sonic RA Max is a performance shoe that’s designed for those who want to tackle the roads. It has a platform that caters to both overpronators neutral runners. Its design focuses on a sporty vibe, which may be appealing to athletes and fitness enthusiasts.
  • The upper unit makes use of a breathable mesh to provide comfortable coverage. Welded overlays and a collar binding grant security for the foot and long life for this product’s façade.
  • VIBE is a midsole configuration that involves two cushioning units. The first one is a full-length foam that delivers responsive cushioning and long-lasting support. The second is a smaller compound placed in the heel section for a springy underfoot experience.

Salomon Sonic RA Max size and fit

The Salomon Sonic RA Max has a standard running shoe length. It features a regular sizing scheme to accommodate the preferences of runners. The available widths are B – Medium for women and D – Medium for men. The semi-curved shape of this road companion mimics the natural curve of the human foot.


The outsole unit of the Salomon Sonic RA Max features geometric decoupling, which is the strategic separation of the heel, midfoot and forefoot sections through deep trenches. These divided units have independent points of contact, so when one segment receives the impact shock, the others don’t get affected. Such a design is believed to smoothen the heel-to-toe transition.

The geometric decoupling of the RA Max causes the platform to go in a more lateral direction during movement, thus countering deviation in pronation.

Wet Traction Contagrip® is an outsole compound that’s meant to protect the rest of the sole unit from wear and tear. It also doles out traction over dry and wet surfaces.

The forefoot area has blown rubber. This compound is soft and responsive, so it can potentially add more cushioning and springiness to each step. Moreover, it is capable of gripping the surfaces with sureness and ease.


Just like in the popular Salomon Speedcross 5, EnergyCell+ is a midsole foam that runs the entire length of the Salomon Sonic RA Max. Its purpose is to cushion the foot throughout the running session and maintain its form, even after many uses. It has an energy-returning capacity to enable enlivened steps.

Opal is a small cushioning unit that’s inserted into the back part of the platform. Its job is to give a bouncy performance. It doesn’t add much to the weight of the shoe.

VIBE is the term used to describe the collaborative functionality of EnergyCell+ and Opal. The combination of these two technologies results in the mitigation of impact forces during the striking phase of the gait cycle.

The Ortholite® molded sock liner is an additional layer of cushioning that’s placed above the primary cushioning system. It’s contoured to the shape of the underfoot, allowing it to give support to the arch and other areas that usually aren’t cushioned.


A breathable mesh material makes up the majority of the Salomon Sonic RA Max’s upper unit. It allows environmental air to seamlessly enter the foot-chamber and maintain a cool and dry in-shoe experience.

The welded sensifit™ overlay system is like a web that covers the forefoot, the sides, and the heel. The fused material reinforces the structure of the upper, making sure that it stays intact. This system also helps the traditional lacing system when it comes to giving a secure fit.

The collar has welded sections to keep it taut and sturdy.

The lightly padded tongue keeps the instep comfortable while allowing more space inside the foot-chamber. A lace-loop in the middle anchors it to the shoelaces, thus preventing it from shifting to the sides during the run.
