Verdict from 10 experts and 11 user reviews

7 reasons to buy

  • Breathability: The mesh upper of Salomon S-Lab Phantasm is very thin, allowing plenty of air in for a well-ventilated ride.
  • Weight: The S-Lab Phantom is lighter than most running shoes with a carbon plate.
  • Ground contact: Those who preferred a close-to-ground sensation appreciate the shoe's minimal cushioning. 
  • Quick-drying upper: There have been reports that the mesh material drains quickly if it gets wet.
  • Traction: Some runners mentioned that the outsole works well on both dry and wet surfaces. 
  • Durability: Several satisfied testers reported that they see no significant wear to the shoe's upper and outsole after 100 miles.
  • Rocker design: The rocker in the midsole encourages a smoother transition. A few runners agreed that it "helps the forefoot roll on and off smoothly" with each footstrike.

2 reasons not to buy

  • Thin upper: The single-layer mesh is too thin. Some runners don't recommend wearing the shoe in cold weather or on muddy surfaces.
  • Fit: According to a number of testers, the upper design is not for everyone. It lacks structure and won't hold the foot as some sock-like engineered mesh upper. 

Bottom line

In the market full of carbon-plated running shoes, Salomon released a model without it. The Salomon S-Lab Phantasm is a traditional racing flat with some modern twists. 

With its unstructured upper and the lack of plate, the S-Lab Phantasm is not a shoe for everybody. For those who prefer a carbon-plated and well-cushioned shoe, the Nike Air Zoom Alphafly Next% is a good option.
