Las 7 Mejores Flat Feet Hiking Shoes

Demanding trails felt like a breeze as we tested the Salomon X Ultra 4 GTX on foot. It has a light build yet feels exceptionally stable because of its sturdy features and unwavering traction, which we discovered in the lab. With its solid mix of agility and support, it’s our best flat-feet hiking shoe.

The midsole kept us secured even as we were loaded with backpacks. A stiff chassis stabilizes the midfoot zone while the straps are connected to the lacing system to increase the shoe’s structure. True enough, we found it difficult to twist our ankles even on unpredictable terrain. We tried to twist the shoe manually and rated it with a high 4/5 torsional rigidity score. Meanwhile, the uber-stiff heel (5/5) held us firmly in place.

Another feature that kept our hikes smooth and controlled was the grippy outsole. It has deep 4.5 mm lugs that kept us surefooted even on loose dirt and wet grass. We were so confident with its traction that we could pick up the pace as we pleased. The shoe’s weightlessness boosted our agility and our scales agreed with a 13.3 oz (378g) reading.

Unfortunately, this shoe will only feel stable for slim to medium-width feet. The midsole runs slightly narrower vs. average, so we recommend that wide-footed hikers find a more accommodating shoe.

The Adidas Terrex Swift R3 GTX is so protective that during our trial sessions, it resembled the foothold and security of a hiking boot. Our lab tests show that, from its raised insole and rigid construction to its robust outsole, its main purpose is to keep us safe and surefooted. It’s undoubtedly our best stable hiking shoe for flat feet.

The midsole erased harsh debris underfoot and our caliper confirms a 36.6/20.7 mm chunk of foam separating us from the ground. It feels balanced, to which our durometer agrees with a 26.0 HA reading, while the insole has raised sidewalls to prevent any spillovers.

Even with its low-cut collar, the shoe’s stiffness makes it feel like a boot. Our sliced midsole reveals the Pro-Moderator technology on both sides of the shoe, which controls excessive lateral movements. Because of this, we couldn’t rate its torsional rigidity lower than 5/5.

The deep 4.4 mm lugs further enhanced the Continental rubber’s grip. No matter what surface we tackled, we emerged safely on the other side. We tested the outsole’s durability in our Dremel test, and it sustained less damage than average, confirming its resistance to wear.

However, this shoe requires a break-in period. Those seeking comfort straight away should explore alternatives.

We instantly enjoyed the suppleness of the Merrell Moab 3 GTX during our trail adventures, making it our top comfortable hiking shoe for flat feet. Our lab tests confirm its exceptional impact protection and easygoing nature while offering support and grip to stabilize the ride.

We measured the stack with our caliper and it emerged an above-average 33.2/22.3 mm, erasing the harshness of the ground. It has some pleasant spring to it and carries our arches well, supported by its firm 35.9 HA reading on our durometer. 

We found the Moab 3 GTX flexible for all the support it brings. In our bend test, it needs only 30.2N force to bend to 90 degrees, close to our lab average. We discovered a nylon shank in the midsole to keep us surefooted, especially in the heel and midfoot areas.

We turned the shoe upside down and it boasted the stellar Vibram outsole. We felt safe on any surface we encountered, also with the help of the deep 4.8 mm lugs we measured.

However, its 15.9 oz (452g) build made lifting each foot quite an effort since it’s 20.5% heavier than average. Those seeking an agile ride should check other options.

The KEEN Targhee III Waterproof is a highly protective shoe, evidenced by its dense upper, firm midsole, and grippy bottom. Even as we encountered moving water, rain, or difficult trails, we remained dry and safe. Already in its name, it’s our ultimate waterproof hiking shoe for flat feet.

The upper looked incredibly tight under our microscope. Even in our light test, nothing passed through, confirming its waterproof nature. Surprisingly, it allowed for some airflow in our breathability test, as it passed through the tongue area. It’s very rare for waterproof shoes to get a 2/5 rating.

Underneath were thick 4.5 mm lugs that deliver excellent traction through its multidirectional pattern. It showed a strong bite through a variety of surfaces and boosted our confidence.

Besides the outsole, the firm midsole served us as our shield underneath. Our durometer confirms this sensation with a 31.0 HA reading, 11.9% firmer than average. Even under heavy loads, the platform reassured us because it doesn’t compress easily. However, this firmness may not suit everyone’s liking. Those seeking a plush and comfortable ride can check more forgiving alternatives.

The Salomon Outpulse made it easy for us to speedhike through the trails. With its responsive and easygoing feel, it was so comfortable on foot. Together with its wide heel and grippy base, our lab confirms it’s the best lightweight hiking shoe for flat feet.

Weighing only 11.6 oz (330g) on our scale, it emerged 12.3% lighter than average. Its streamlined build and fluid midsole make it easy to maneuver along unpredictable terrain. Our bend test validates it’s 19.2% more flexible than average.

Outpulse has a bouncy and energetic sensation that enhances its lightness. Our durometer shows the cushion is a soft 22.6 HA but doesn’t feel so unstable that our feet sink into it. Overall, it protected us from landing impact and made the ride more enjoyable.

We measured the heel to be slightly wider than average at 88.0 mm, contributing to more secured strides. Underneath is a grippy base composed of deep 4.1 mm lugs. With varied shapes and multi-directional positions, we found it to be effectively grippy on a wide range of surfaces.

However, the narrow forefoot and toebox will feel constricting for those with broad feet. Those who prefer more real estate for swollen feet should check alternatives.

Comfort is a top priority with the Hoka Skyline Float-X as it provides maximum breathability and cushioning to our outdoor adventures without compromising support. Our lab test confirms its steady stream of ventilation, making it our top summer hiking shoe for flat feet.

Even with the knit upper’s plush feel, it’s surprisingly breezy! We pumped smoke into the shoe and it escaped almost instantly, which is why we rated it with a perfect 5/5 breathability score—a rare breed among hiking shoes.

The comfort doesn’t stop there: we’re welcomed with a generous 39.0/31.0 mm stack that feels nice and springy. Our sliced midsole reveals two foam densities: a soft 22.0 HA below our foot, and a firmer 27.9 HA that makes ground contact for better stability.

In addition to the firm base foam, a Pebax plate is sandwiched between the two layers and adds structure to the shoe. It’s positioned under our arch for better support. The 117.6/101.6 mm midsole also runs wide and mitigates any potential imbalances.

However, the toebox is on the narrower side so we don’t find it ideal for those who have broad or square-shaped feet.

While the average hiking shoe costs €160, we’re surprised that there’s a €100 shoe available in the market: the Adidas Terrex AX4! Both our trail sessions and lab results can confirm its protective nature through its water-repellant upper, reliable traction, and firm base. For all these and more, it’s our best budget hiking shoe for flat feet.

The Terrex AX4 provides impressive resistance to light rain and wet grass. It has water-repellant capacities while allowing for some nice airflow, evidenced by its 3/5 breathability score in our smoke test. We enjoyed the protection it brings without suffocating our feet with body heat.

Even as we tackled wet surfaces, the grippy base gave us the confidence to hike without thinking too much. We measured the chevron lugs to be 3.7 mm deep, while a heel brake was present to assist us during downhill trails.

The Terrex AX4 feels very stable and we discovered two main contributing factors in the lab. First, the foam is 40.8% firmer than average, avoiding any unwanted compressions. Second, the base is wide enough to help us find our footing.

However, the toebox space is more cramped than usual. We recommend those with wide or voluminous feet to size up or check more accommodating shoes.
