8.5Overall score
A good thoroughly-cushioned heavy-duty running shoe for optimal comfort
The third model in the brand's Sonic series, the Salomon Sonic 3 Confidence, is all about added cushioning, support, and traction. The Confidence gives users an added "spring" in their step with its forward-propelling design, serving to energize runners and make it that much easier for them to achieve their desired speed. The Confidence also provides reliable traction for navigating a variety of terrains —though it is probably best for standard road use. Compared with its siblings, the Accelerate, and the Balance, the Confidence stands out for its optimal padding, which better accommodates long-distance runners with this added cushioning. Also, despite the thick stack height of 31 mm for the heel and 21 mm for the forefoot, the cushioning is rather firm to offer a good pop for a more responsive ride. Confidence also commented that the lacing area and tongue have an elastic quality, which means that the shoe can be molded to each user's uniquely-shaped foot. Overall, it's a supportive and reliable running shoe that works perfectly for most longer outdoor excursions and activities. There are a few potential drawbacks to the Confidence's design, including a restrictive midfoot area and an insecure heel collar, which isn't as supportive as the rest of the shoe. Users also noted that the Confidence's design is much clunkier than the Accelerate or the Balance. Perhaps because of this overall big design, the shoe itself tends to run on the larger side, so it's a good idea for users to size down when purchasing. In addition, the unusually-dense mesh fabric of the Confidence combined with its gusseted tongue takes away from foot breathability, especially when compared with other Sonic options. Pricing for the Salomon Sonic 3 Confidence is $130, which is decent, but perhaps not an excellent value given some of the downsides of the shoe. Ultimately, the Sonic 3 Confidence is a good choice for beginner to moderate runners planning to run medium to long distances, due to its extra padding for absorbing the shock of pounding.

  • To begin with, we find Contagrip on the outsole of the Solomon Sonic 3 Confidence. It is a blown rubber, a lightweight and flexible material that allows the shoe to follow the movements of the foot for more bounce and springe. This is especially important during the propulsion phase when the foot pushes the ground to launch the body. In addition, you can easily tackle road surfaces even in the rain thanks to the platform’s great grip.
  • The outsole of this road shoe also has flex grooves that allow the sole to bend to accompany the foot’s movements during the stride. Thus, their objective is to allow for greater flexibility for greater comfort.
  • Finally, the four-part decoupled configuration is designed to better isolate the impact on each important part of the foot as the stride unfolds for more effective cushioning and a better transition from the heel to the forefoot.


  • The midsole features the Optivibe cushioning technology. This is a foam material composed of olefin from the Dow Infuse brand. It is known for its softness and natural bounce, making it an ideal choice for sports shoes. It ensures that it absorbs shocks throughout the run for greater comfort. In addition, this configuration should offer maximum responsiveness for a more bouncy ride.
  • Lastly, the OrthoLite insole conforms to the anatomy of the foot and completes the cushioning of the shoe. It also improves the ventilation by wicking away moisture.


  • The upper of the Salomon Sonic 3 Confidence features an engineered mesh. This configuration provides a snug foot lockdown and allows air to circulate for a pleasantly cool feel.
  • Furthermore, the Ortholite Impressions technology consists of a thin foam tongue that hugs the contour of the upper part of the foot. It uses 50% bio-oil to limit its impact on the environment.

Frequently asked questions (FAQ)

How does the Salomon Sonic 3 Confidence fit?

This road shoe follows a regular sizing chart. However, it does fit a little large, and runners who have tested it recommend that you choose a size smaller. It’s recommended to try it on in-store to be sure if the fit is as comfortable as possible.

Is the Sonic 3 Confidence suitable for athletes who overpronate?

This model is a neutral shoe. As such, it is designed to suit all athletes regardless of their type of pronation. It does not have any stability features to correct the stride and avoid overpronation. Remember that in any case, stability shoes are no more effective than neutral shoes in limiting the risk of injury. We, therefore, recommend that you select your running sneakers according to their comfort, the most important criterion. So you can use this model independently from your pronation, as long as it is comfortable.

Is this road shoe suitable for heavy runners (85 kg/187 lbs or more)?

Only one scientific research study so far has looked at the relationship between weight, risk of injury, and sole thickness. According to the conclusions of this study, shoes with very thin soles (minimalist) may increase the risk of injury for athletes who weigh more than 156 lbs/71 kg. Apart from this, there are no recommendations for other categories of running shoes. The Sonic 3 Confidence has a relatively thick sole and should, therefore, be suitable for most runners regardless of their weight.

Are these shoes suitable for running a marathon or half marathon?

This Salomon road shoe is very well suited for different types of distances and workouts, but with its comfortable cushioning, it is primarily intended for long distances. Its 31 mm thick sole under the heel and 21 mm thick under the forefoot make it a good choice for marathon running.
