  • 84 / 100 | Andrew Skurka

    The Sonic Pro 2 wants to go fast. Its firm ride efficiently transfers energy, but it’s not the type of shoe I prefer for long slow cruises on pavement.

  • 88 / 100 | Majzel

    They are first and foremost a good road running shoe with comfort beyond what you would expect for the price and weight.

  • 87 / 100 | Running Magazine

    ...the Sonic Pro 2 offers a stiff but supportive ride with minimal added cushioning in an exceptionally lightweight package. This makes for a quick and speedy shoe that is great for faster efforts including workouts and races.

  • The Sonic Pro 2 is a light and responsive Salomon road-running shoe that is aimed at runners with medium-high to high arches. This edition boasts of a more modernized fit than its predecessor, thus making it ideal for run workouts and races.
  • It has an open mesh upper with quick-drying capabilities, Sensifit™ overlays that give a secure feel, and the Endofit™ system with a sock-like texture that strives to bring unparalleled comfort.
  • Featuring EnergyCell+, the midsole offers lightweight responsiveness. It sits on an outsole that uses Wet Traction Contagrip® which provides the necessary grip on the pavement.

This shoe has a standard running shoe length and is designed to fit runners with a low to medium foot volume. Width profiles are D – Medium for the men’s version and B – Medium for the women’s version.

Same as in the popular Salomon Speedcross 5, the outsole of the Sonic Pro 2 uses the Wet Traction Contagrip®, a premium rubber compound that works by providing durability and preventing slippage on wet surfaces. It also reduces the risk of damage caused by rough surfaces.

Salomon also introduces Geometric Decoupling, a system focusing on making a smooth transition to allow the foot an easy touchdown and propulsion. It works with the notion that forward shift is essential for the runner.

The Salomon Sonic Pro 2 features the Vibe technology, which is a combination of two cushioning structures, the EnergyCell+ and the Opal. These components work together to reduce fatigue-causing vibrations without sacrificing responsiveness.

EnergyCell+ is a high-rebound, compression-molded EVA midsole compound that aims to supply exceptional energy return, as well as substantial cushioning and durability.

On the other hand, Opal is a cushioning compound inserted into the midsole; it produces a soft and comfortable underfoot ride with the benefit of high-rebound. This mixture is lightweight, durable, and resistant to extreme temperatures.

It also has 3D Profeel, a thin TPU film that adds protection, but not at the expense of ground sensation.

The sock liner has a combination of Ortholite® foam and an EVA heel cup. It creates a fresh, dry, and healthy environment for the foot. It’s also designed to last long, unlike other sock liners.

The breathable open mesh upper has a seamless finish and a flexible exoskeleton, promising an improved durability and control compared to its predecessor. This material dries quickly after getting wet, thus promoting a distraction-free run.

The interior lining is a soft and smooth material directed to cover sharp edges and prevent irritation and injury.

The Sensifit™ overlays cradle the foot, resulting in a secure, snug, and customized fit all around. They work hand in hand with the Endofit™, an internal sleeve that brings a sock-like sensation and active ground feedback.

This shoe also has 3D Flex, which utilizes two seamlessly integrated panels on the medial and lateral sides of the forefoot. It works by relieving pressure around the metatarsals and forefoot during the stride and foot expansion. It offers the optimal combination of free movement and foothold.

With the traditional lace-up closure, there is familiarity in adjustability and comfort.
