Analysis: where they really differ

It is the same mud shoe, with a 10 mm drop and very aggressive lugs. The GTX version adds a waterproof Gore-Tex membrane at the cost of 30 g and less breathability. The standard version drains better once water gets in.

Choose the Salomon Speedcross 6 if…

  • You run in heat or in races with river crossings (water drains faster).
  • You want the lighter version (298 g).
  • You want the deepest lugs (5.8 mm).

Choose the Salomon Speedcross 6 GTX if…

  • You run in winter, rain, snow or cold puddles.
  • You want dry feet on muddy training runs.
  • Dry feet matter more to you than breathability.
