  • Day-one comfort: Right from the get-go, the Salomon X Ultra 4 is lavishly comfy, say numerous trail-goers.

  • Stable: Its ability to keep your footing steady (not tipping over to any one side) on uneven terrain is incredible.

2 reasons not to buy

  • Questionable collar: About a handful of reviewers, who also happened to be X Ultra 3 owners, find the ankle cuff of the 4th iteration too high.
  • Unreliable midfoot (women’s variant): Its arch zone could be more supportive, say a couple of female testers.

Bottom line

Where the trail becomes rougher without warning, but you prefer to speed up anyway, the X Ultra 4 has you covered. Indeed, this svelte-yet-stout Salomon hiker will make you bolt across treacherous terrain well-protected as if you were in a pair of beefed-up trail runners. It has its flaws, but if you can reach a compromise, the X Ultra 4 is quite a keeper.

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.

Takeaways:

  • 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.
