The Salomon Sonic RA 2 is a good choice for long distance running and those who have a slightly higher arch than normal. The shoes provide excellent cushioning and a wider toe box for a natural toe splay. If you are a neutral running that does not need much support, these shoes are a good option for you.

In the midsole, you will find Unique Vibe Technology, which is a combination of EnergyCell+ and Opal technologies from Salomon. The Opal midsole maintains its shape and cushioning in different temperatures and it doesn’t break down over long runs. The EnergyCell+ part of the midsole is responsive and provides good rebound. The combination of the two technologies keeps vibrations at a minimum to help reduce muscle fatigue while providing solid cushioning.

Changes have been made in the upper with reconfigured overlays, which reduce the chances of irritation. The engineered mesh and Sensifit upper conforms to the shape of your feet so it feels like a customized fit.

Contagrip is found on the outsoles, which is a combination of materials that are different levels of densities to offer durability. The outsole also features Geometric Decoupling — which is similar to the previous versions of the Sonic RA — to allow for a smooth heel to toe transition. Overall, the outsole provides excellent traction on a variety of surfaces, both wet and dry.
