Updates to Salomon X Ultra 4

The 4th-generation X Ultra from Salomon comes packed with enhancements that give trail-goers even more reason to stay on the go. The following are some of its notable improvements from the X Ultra 3.

Chassis change. The X Ultra 4’s new chassis delivers enhanced balance over rocky terrain. That said, unlike the chassis of the previous version, this stabilizing component is more flexible around the forefoot, making push offs bouncier.

Flared heel. Salomon engineers gave the X Ultra 4 a flared heel. Adventurers, particularly heel strikers, will be able to pull off more natural transitions with it—lessening lower leg fatigue.

Shaved-off weight. You can go faster and be more mobile wearing this hiker as it is lighter than its predecessor by 10 to 20 grams a pair.

The X Ultra 4 family

Salomon’s compelling lineup is made even more robust with the X Ultra 4. But the better news? It has two other siblings in the X Ultra 4 GTX and the X Ultra 4 Mid GTX.

The former is everything the X Ultra 4 is but with waterproofing. The latter, on the other hand, comes with better ankle support on top of full over-the-ankle water protection.


  • Opt for the X Ultra 4 if you wish to be as agile as possible in dry conditions.
  • For hikes involving some rain and puddles whose depth is no more than 2 inches, the X Ultra 4 GTX seems to be a good choice.
  • Their mid-cut sibling is reliable through streams and can withstand heavier rains.
