    Overall, I find this to be a super successful update. The upper is far more comfortable, far more flexible; the ride is much smoother.

  • 90 / 100 | Seth James DeMoor | Level 3 expert

    [The shoe] ...very comfortable through the collar... [and] that midsole, just nice and responsive but supportive as well.

  • 89 / 100 | Believe in the Run | | Level 4 expert

    There’s a simplicity about the RA MAX 2 design this year, but it works well.

  • 88 / 100 | Road Trail Run | | Level 4 expert

    I am excited to run even more in this shoe now that the upper issue has been ironed out, and even more excited to see where they go from here.

  • 98 / 100 | The House Outdoor Gear | | Level 1 expert

    I think that these are a pretty good [reiteration]. I actually like this one a little better than Max 1.

  • 95 / 100 | Front Runner Sheffield | | Level 1 expert

    If you're gonna be popping miles for a spring marathon or just want a really kind of comfy, fairly light shoe... then the Sonic Max RA 2 is for you.

  • Salomon’s second iteration of the Sonic RA Max now provides even more stability for users who do their daily running. Aside from the usual benefits of a stability running shoe, the Sonic RA Max 2 offers additional cushioning to give users a comfortable and responsive ride to help log more miles.
  • The shoe presents an upper of engineered mesh that provides a customized and contoured fit. It is assisted by Salomon’s signature shoe technologies that contribute to gently securing the foot in place and giving a pleasant wear experience.
  • The midsole utilizes the features of EnergyCell+ and VIBE technology to deliver a cushioned, supportive ride while also minimizing the impact and its accompanying fatigue. The platform is partnered by Contagrip as the outsole, equipping the shoe with traction and flexibility throughout the gait cycle.

The Salomon Sonic RA Max 2 runs smaller than the standard running shoe, as shown in the sizing scheme in the brand’s website, as well as relayed by reviewers. It is highly recommended that buyers go a half-size higher than their usual preference to get a more accurate and comfortable fit. The Sonic RA Max 2 comes in Medium width for both the men’s and women’s versions.

The blown rubber Contagrip outsole of the Salomon Sonic RA Max 2 is made from an ultra-lightweight formula that gives a plush feel and ground sensation. The blown rubber works hand-in-hand with another compound, called the Contagrip FA, which takes the form of the outsole’s lugs. The lugs of the Sonic RA Max 2 are flat and wide, providing the necessary friction on hard surfaces. It also delivers durability and traction that is ideal for road running.

The outsole also utilizes the Geometric Decoupling system, which gives the platform a symmetrical layout to allow effortless load guidance. This results in a more efficient heel-to-toe transition. With Geometric Decoupling, the foot receives just the right amount of energy for a smooth stride.

Salomon’s VIBE Technology leads the way in providing functionality in the midsole of the Sonic RA Max 2. This proprietary feature combines two materials—EnergyCell+ and OPAL—that work together to reduce fatigue by dispersing shock vibrations. Each component has its own task, as well.

The EnergyCell+ midsole foam is lightweight and contributes to a responsive ride. Made from compression-molded ethylene-vinyl acetate (CMEVA), the EnergyCell+ supplies maximum-level energy return. It is also built to be durable and to provide substantial cushioning. Another Salomon running shoe that utilizes this feature is the Speedcross 5.

Meanwhile, the OPAL cushioning compound augments the soft underfoot feel of the midsole. This material is resistant to extreme temperatures.

The shoe includes a molded Ortholite sockliner for superior cushioning, breathability, and durability. It has an antibacterial quality, which aids in keeping the foot free from odor and moisture.

The Salomon Sonic RA Max 2 uses an engineered mesh upper to provide the foot with lightweight and breathable coverage. It is welded to stay durable. The upper is also reinforced with the brand’s Sensifit construction, which serves as overlays that cradle the foot for a secure, snug, and customized fit.

The welded soft collar adds to the comfort level of the Sonic RA Max 2. It also gives a more ergonomic feel, as well as helps lock the heel in place.
