Salomon X Ultra 4 Mid GTX Review
Last updated: June 2026
The Salomon X Ultra 4 Mid GTX sits in a crowded but important category: lightweight waterproof mid hikers that work for trail days and overnight trips without weighing you down. Salomon has refined this line through four generations, and the X Ultra 4 shows it. Gore-Tex membrane, Contagrip MA outsole, and a proprietary QuickLace system come together in a package that Switchback Travel calls a near-ideal combination of weight, comfort, protection, and durability. Who it is not for is as important as who it is, and the narrow last and QuickLace quirks mean some buyers will want to look elsewhere.

Terrain and Distance: Where This Boot Works
The X Ultra 4 Mid GTX is designed for day hikes and weekend backpacking trips, typically with loads under 35 pounds. It handles moderate to technical terrain well, including hardpack, wet rock, and light scree, but is not the right tool for sustained alpine scrambling or long routes where durability across hundreds of miles takes priority.
Think of it as the bridge between a trail runner and a heavy leather boot. You get meaningful ankle support from the mid-cut collar, Gore-Tex protection, and reliable traction from the Contagrip MA outsole. That combination covers the needs of most day hikers and weekend backpackers. For sustained technical routes or heavy loads, a stiffer boot offers more support.
Waterproofing and Breathability
The Gore-Tex membrane does its job well. In sustained rain, stream crossings, and wet-grass meadow sections, feet stay dry consistently. This is one of the stronger performers in the mid GTX category for wet-weather protection.
Breathability is the trade-off, and the X Ultra 4 does not escape it. In temperatures above 65°F, the Gore-Tex liner traps heat and moisture inside the boot. Hikers who run warm or live in places where summer hiking dominates should consider the non-GTX version for dry conditions, where breathability matters more than waterproofing.
Contagrip MA Outsole: Traction on Trail
Salomon's Contagrip MA outsole uses a multi-directional lug pattern built for mixed terrain. On wet rock and hardpack, traction is reliable and consistent. On loose scree, the sole bites well enough for confident footing.
Where it gives back a little is on thick mud. The lug spacing clogs faster than more aggressive outsoles. For Pacific Northwest hikers dealing with mud-heavy trails through spring, a boot with wider lug separation, or dedicated gaiters, may help in the worst conditions.
Fit and Sizing: What to Know Before You Buy
The X Ultra 4 Mid GTX runs narrow, particularly through the forefoot. Hikers with average to narrow feet typically find the fit secure and precise. Hikers with wide feet or high-volume feet frequently cite pressure on the outside of the forefoot and pinching at the toe box.
Salomon offers a wide (2E) option in select colorways, but availability is limited. If you are between sizes, size up a half size. Break-in time is relatively short for a mid boot. Most wearers report 2 to 3 days of use before the boot feels fully broken in.
QuickLace System: Pros, Cons, and Failure Modes
Salomon QuickLace is a single pull-cord system with a lace pocket. The idea: one tug snugs the boot, then the cord tucks away. On trail, it is fast. Pull, stow, go. No tying, no fiddling.
The trade-offs are real. First, you get one tension across the whole foot, not the zone-by-zone customization that traditional laces allow. Hikers who prefer a looser midfoot and tighter ankle have fewer options here. Second, the cord is the durability weak point. Buyers consistently report fraying and breakage at around 300 to 500 miles of use. Salomon sells replacement cord kits, and the swap is manageable, but it is a known failure mode worth planning around. If cord longevity matters, test the boot on shorter trips before committing to a long route.
How It Compares to the Moab 3 and the Anacapa
Vs. Merrell Moab 3 Mid GTX: The Moab 3 is wider, softer, and less expensive. It suits wide or flat feet and casual day hikers who prioritize all-day comfort on maintained trails. The Salomon is lighter, more technical, and has better traction on mixed terrain. For narrow-foot hikers tackling varied trail conditions, the X Ultra 4 is the call. For wide-foot hikers or those mostly on groomed paths, the Moab 3 fits more people and costs less.
Vs. Hoka Anacapa Mid GTX: The Anacapa maxes out cushioning with its thick midsole, making it the pick for hikers who want maximum comfort on groomed trails. It runs wider than the Salomon and suits average to wider feet. The Anacapa is priced higher. For cushioning-first buyers on maintained terrain, the Anacapa earns consideration. For mixed terrain, wet conditions, and technical footwork, the Salomon delivers more performance per dollar on mixed terrain.
