Salomon X Ultra 3 GORE-TEX: mountain hiking review

The Salomon X Ultra 3 GORE-TEX is a low-cut hiking shoe combining a waterproof membrane, a supportive construction and a lugged outsole. It is designed for walking on uneven trails and wet ground rather than clocking up running miles.

Its appeal lies in the balance between support and freedom of movement: it offers more protection than many lightweight sports shoes while leaving the ankle free. The trade-off is a relatively snug fit and less ventilation than a shoe without a membrane.

A low-cut mountain shoe

The third generation of the X Ultra family was designed for people who prefer a hiking shoe to a high-cut boot. Its upper combines fabric and synthetic materials with reinforcements in exposed areas, including the toe. The construction is intended to hold the foot in place when the trail calls for steps over rocks, roots or sloping surfaces.

The low-cut profile allows the ankle to move freely and makes the shoe easy to put on and take off. However, it leaves that area more exposed to knocks and water ingress than a mid-cut boot. Shoe height should not be mistaken for a guarantee against ankle injuries.

As a guide, quoted weights for this generation are around 380 grams per shoe for men and 330 grams for women, although they vary by size and version. These are approximate figures, not weights that apply to every pair. When buying, check that the figure refers to the low-cut shoe rather than the Mid boot.

GORE-TEX membrane: protection and ventilation

The GORE-TEX membrane helps prevent water from outside passing through the shoe while allowing some water vapour produced by the foot to escape. It is useful in wet grass, rain and shallow puddles, common conditions on winter walks or in damp mountain areas.

That protection has physical limits: water can enter through the top, and a shoe that gets wet inside can take time to dry. A membrane in good condition also does not stop the foot from sweating. On a hot hike, moisture inside the shoe can affect comfort too.

Compared with an equivalent non-membrane version, the usual trade-off is more protection from water and less ventilation. On a dry, sunny outing inland in the Valencia region, that extra barrier may be less appealing than on a cold walk after several days of rain.

Fit and lacing: a shape worth trying on

The SensiFit system wraps around the midfoot and works with the Quicklace closure, which tightens the laces in one movement. Excess lace tucks into a pocket on the tongue. Together they are designed for a precise fit, particularly useful when the foot tends to slide forward on descents.

That close fit may feel uncomfortable for anyone who needs plenty of room across the forefoot. When trying on the shoe, checking that the toes have space and the heel does not lift excessively matters more than seeking a compressed feel. Your usual size in another brand will not necessarily fit the same way.

Quicklace also has a practical limitation: it does not allow the same zone-by-zone tension adjustment as conventional laces. Anyone who needs a very particular fit over the instep should consider that before choosing this system.

There are men’s and women’s versions. Besides the approximate weight differences, fit can vary between them, so equivalent sizes should not be assumed to have identical volume. For sizing, the most useful starting point is the Salomon chart for the specific version, alongside a foot measurement and a fitting with hiking socks.

Contagrip outsole and stability on descents

The Contagrip rubber outsole has lugs pointing in different directions to support traction. The Descent Control construction focuses on downhill walking, where the forces on the foot differ from those on a climb and the shoe needs to help keep each step controlled.

On dirt, gravel or moderately muddy trails, the tread provides contact and traction for walking over changing ground. On a compact track or pavement, the lugs also touch the surface, but that is not where their design is best put to use.

The Advanced Chassis adds structure around the heel and midfoot. It does not remove the need to adjust your footing: grip can drop considerably on wet, smooth rock, even with a mountain shoe. On a steep descent, the surface matters as much as the tread pattern.

Cushioning and underfoot protection

The EnergyCell midsole uses EVA foam to cushion each step. It is designed as a walking shoe with a firm, protective platform, rather than a running model intended to deliver an especially soft ride or high energy return.

The OrthoLite insole adds a layer of underfoot comfort, while external reinforcements protect against scuffs from rocks and vegetation. The result is a trail-oriented construction, where side protection matters alongside walking comfort.

On a long walk over hard ground, that firmness may suit someone looking for a stable platform, but cushioning preferences remain individual. A heavier pack also changes the demands on feet and legs: shoe choice should account for the load and duration of the outing as well as the terrain.

Fast hiking versus trail running

The athletic silhouette may resemble a trail-running shoe, but its main job is walking. For a runner who alternates walking with short running stretches during a hike, the construction may be sufficient; for regular training, a dedicated trail-running shoe generally offers a build better suited to the running stride.

The distinction can show up in flexibility, weight and cushioning, depending on the model used for comparison. There is no particular pace or body weight at which this X Ultra 3 automatically becomes suitable for running. The decision depends on its main use and how it actually fits the foot.

On rocky outings with a light pack, its design supports brisk walking. For a long trek with a heavy load or specific protection needs, a sturdier trekking shoe or boot may be worth considering. That does not make a high cut mandatory: it changes the coverage and construction around the foot.

Low-cut and Mid versions are not the same shoe

The family also includes a Mid version with a higher collar. Although it shares the name and membrane, it should not be treated as identical in weight, lacing or coverage. Some retail descriptions mix features from both, making the full name and pictures of the pair important.

The low-cut version reviewed here leaves the ankle free and uses Quicklace. The Mid covers more of that area and may have a different configuration. When comparing listings, also check whether they refer to men’s or women’s footwear and whether the item is actually the third generation, as later versions in the range may have design changes.

Buying an older generation: what to check

The X Ultra 3 is an older generation, and a pair offered for sale may have been stored for some time. Even if it is new, check the condition of the outsole, bonded areas and lacing system. Cracks, separation or visibly deteriorated rubber are reasons to reject the pair.

When buying online, the ability to try the fit at home and the return conditions are especially valuable: waterproofing and a good outsole cannot fix a shoe that is too narrow. It is also worth checking whether the listing describes a new, used or refurbished product.

Subsequent wear cannot be reduced to a universal mileage figure. Abrasive rock, pavement, storage and frequency of use affect each pair differently. Heavily worn lugs, separation or membrane damage alter the functions for which the shoe was chosen.

Terrain shapes the buying decision too

On a walk through damp woodland, protection from water may justify a more enclosed shoe. On dry, hot trails, ventilation may matter more than waterproofing. The same route places different demands on footwear on a cold winter morning and on a summer day.

For people who both run and hike in the mountains, separating those uses helps avoid attributing qualities to footwear that it does not have. The X Ultra 3 GORE-TEX serves a specific purpose: a low-cut, structured hiking shoe equipped for wet conditions, with a different construction from a training shoe.
