How We Tested Water Shoes

We thoroughly tested these water shoes side-by-side in the wet Pacific Northwest. We took them canyoneering, whitewater packrafting, hiking and bushwhacking along rivers and subalpine wetlands, and running around lakes in pouring rainstorms. We also wore them for the more casual activities folks often use these shoes for — grabbing drinks with friends and even days at the office.

We also spent lots of time testing with two shoes at a time, a standard testing procedure here at OutdoorGearLab that allows us to make detailed, side-by-side comparisons in the real world.

Comfort


While comfort depends partially on fit, we evaluated shoes for how supportive they were, how well they protected our feet over rough terrain, how well they drained water on land, and how adjustable they were. While we list the relative volume of fit for each shoe, we did our best to ignore how the shoe fit our particular feet when rating this metric.

In the water, we were looking for whether shoes stayed securely on our feet while swimming and protected us from rocks and sticks hidden underwater. On land, we walked on trails, cobbles, boulders, and bedrock to see how quickly our feet got tired and whether we felt excessive pressure in rough terrain.

We tested water shoes both on land and in the water to evaluate comfort and support.

Traction


We test traction in real-world conditions, usually wearing different shoes on each foot to enable side-by-side comparisons. This allows us to rank shoes in terms of their traction and establish which ones are the stickiest.

Relying on real-world conditions, we made sure to test each shoe on a combination of hard and soft surfaces. For hard surfaces, we evaluated traction on wet and dry rocks and logs. We even made sure to test both rough, grippy rock, like coarse granite, as well as smoother, generally slicker rock, like metamorphosed sandstone. For soft surfaces, we tested shoes on mud, dirt, and duff to see how well they kept from slipping.

Side-by-side testing allowed us to determine which shoes stuck best to a variety of surfaces.

Warmth


Unless you're lucky enough to live in a place with super warm water, you'll probably need some insulation to keep your feet warm. When evaluating shoes for warmth, we looked at two things:

First, what are the upper materials, and how much insulation do they provide on their own? Shoes with no drainage and thick uppers tend to be very warm. While they can be too warm at times, you can usually cool off by simply getting wet.

Second, how adjustable is the shoe, and do they fit well with a range of sock thicknesses? For shoes not made of neoprene, warmth comes only from being able to stuff in insulation, either in the form of wool, neoprene, or layers of socks underneath a drysock. To score high in this metric, shoes without lots of built-in insulation had to be adjustable enough to fit multiple layers of socks and a drysuit sock, while still being comfortable with thin or no socks.

We also tested shoes with and without insoles. Removing the insole opens up a lot of volume in the shoe, which can add warmth and enable you to add more insulation. Shoes scored higher in this metric if they had removable insoles and were still wearable without their insoles.

The Astral TR1 Junction (left) scored highly for warmth due to its adjustability and functionality  even with thick neoprene socks. The Adidas Hydro_Lace (right) scored similarly due to its built-in neoprene insulation.

Versatility


Water shoes can be great to have for a variety of activities, from paddling or rafting to canyoneering or river walking. We used these shoes in as many environments as we could think to expose them to — whitewater boating, canyoneering, hiking, creek walking, and just hanging around lakes and rivers. To score high in versatility, we needed to be able to reach for a pair of shoes for multiple activities confidently.

Sensitivity


Water shoes should provide a decent level of sensitivity to allow you to feel the ground beneath your feet. During testing, we evaluated for ground feel, which can allow proprioception, or the ability to sense one's position relative to their environment.

While walking both in and out of water, we noted whether we had a good sense of what we were walking on and whether shoes felt like bricks or gave us good, flexible ground feel. In the water, we waded and swam to evaluate drag and ankle flexion.

We loved the NRS Paddle for its warmth and excellent flexibility. Swimming around in this pool with this shoe was really fun.

Durability


While our testing period is too short to test durability exhaustively, we use our years of experience using and abusing water shoes to judge whether shoes will hold up to the demands of wet environments. While we note any obvious failure during our testing, evaluation for this metric comes primarily from examining each shoe's construction and materials

We look for build quality, stitching, glue seam appearance, the use of reinforcing materials, and whether reinforcements are stiff and rigid or soft and pliable. We also note any spots of premature wear following our testing that we suspect will turn into durability issues later on.
