The verdict

Pick one in ten seconds

Figures as published by each brand (or the named retailer); each value links to its source. "Not published" means the figure isn't in our cited sources.

Width and fit for wide feet

This is where the two boots split. Merrell sells the Moab 3 Mid Waterproof in Medium and Wide for both men and women, sizes 7-15 for men and 5-12 for women. Salomon sells the X Ultra 5 Mid GTX in men's D - Medium and E - Wide, but the women's version comes in B - Medium only, with no wide listed. If you're shopping for a woman with wide feet, that difference alone settles it in Merrell's favor; for men, both offer a wide option.

Support, chassis and weight

The Moab 3 Mid Waterproof uses a molded nylon arch shank under a Super Rebound Compound midsole with a Merrell Air Cushion heel, at 495 g (men's, half pair). The X Ultra 5 Mid GTX builds around Salomon's Advanced Chassis with an EVA midsole and quickLACE lacing; Salomon publishes a women's weight of 13.75 oz but doesn't list a men's figure. Reviewers and Salomon's own marketing describe the X Ultra line as built for a faster, more agile stride, while the Moab leans toward a wider, more accommodating fit.

Lacing and heel hold

The X Ultra 5 Mid GTX uses Salomon's quickLACE system, a single pull-cord lacing setup built for fast on-and-off rather than a traditional lace-up. The Moab 3 Mid Waterproof's listing doesn't mention a speed-lace system, so plan on standard laces and a normal lacing routine. If your heel lifts in either boot, a heel-lock wrap fixes that without buying a different size; see hiking boot lacing techniques for how to tie one, and pair it with a sock built for friction rather than a thin liner; our picks are in the best hiking socks.

Waterproofing: named membrane vs. in-house

The Salomon uses GORE-TEX, a third-party membrane with its own published waterproof standard. The Moab 3 Mid Waterproof uses Merrell's own in-house membrane, which Merrell doesn't name or attach a third-party rating to on the pages we checked. Both are marketed as waterproof; only one comes with an outside standard attached to that claim. If you want the GORE-TEX name on a Moab specifically, Merrell also sells a Moab 3 Mid GORE-TEX version, sized the same as the standard Moab 3 Mid.

Neither boot is the last word on fit or support for every foot. For a wider-forefoot option in the same low-cut family as the X Ultra, see the best hiking shoes, and if you want to see the Moab 3 stacked against a dedicated wide-fit boot rather than the X Ultra, see KEEN Targhee vs. Merrell Moab. If ankle history rather than width is your main concern, the X Ultra 5 has its own head-to-head against a taller Salomon boot in Salomon X Ultra vs. Salomon Quest.

Who should skip both

If you need more room than a Wide letter width gives you, or your feet are wide at the forefoot specifically rather than throughout, a dedicated wide-toe-box shoe may fit better than either mid boot here. See the best hiking shoes for lower-cut options that include wide-toe-box picks.

What it gets right

  • Sold in Wide for both men and women

  • Stack height not published

Skip it if…

you hike mostly in hot, dry weather: a membrane slows drying and adds heat, and the breathable Moab 3 Mid does the same job cooler.

Everyone in this category says they tested it. We didn't, and we say so. Every pick is scored from the brand's published specs, width and size charts, warranty terms and cited research, against the problem this page is about. The sources are listed at the bottom of the page.

Scores are editorial judgments from that published data, not lab results. Nobody pays for placement, and a missing spec is scored neutral, never guessed. The full rubric is on How We Choose.

FAQ

Questions people ask

Which is better for wide feet: the Merrell Moab or the Salomon X Ultra?
The Merrell Moab 3 Mid Waterproof, if you need a wide width in a women's size: it's sold in Wide for both men and women, while the Salomon X Ultra 5 Mid GTX's women's version is Medium only. For men, both offer a wide option.
Does the Salomon X Ultra 5 come in wide?
Yes, for men: Zappos lists the X Ultra 5 Mid GTX in men's E - Wide. The women's version is listed in B - Medium only.
Is GORE-TEX more waterproof than Merrell's own membrane?
We couldn't find a third-party waterproof rating for Merrell's in-house membrane to compare against GORE-TEX's published standard. Both boots are marketed as waterproof; GORE-TEX is the one with an outside name and standard attached to that claim.
Which boot is lighter, the Moab 3 or the X Ultra 5?
Merrell publishes 495 g per boot (men's, half pair) for the Moab 3 Mid Waterproof. Salomon doesn't publish a men's weight for the X Ultra 5 Mid GTX on the pages we checked, only a women's figure of 13.75 oz, so a direct men's comparison isn't possible from published specs.
