KEEN Clearwater CNX Review

The Keen Clearwater is a relatively strong performer across the board, putting up solid scores in comfort, traction, and stability. This is also one of the most attractive of the Keen models, though we still find them less stylish than open-toed models. The only metric where the Clearwater falls short is adjustability. With a single cinch strap at the top of the foot that tightens the cord in a shoelace-like pattern, it isn't easy to fine-tune adjustments. The ankle also lacks adjustment, but many of our testers worked around this by simply stepping on the ankle strap when they needed to quickly slip the shoe on and off. Note that this is a fairly narrow shoe (especially by Keen standards), so those with wide feet may want to look at other options.

Performance Comparison

The Clearwaters are surprisingly light and sleek while also being durable adventure shoes.

Comfort

The Clearwater performs well in the comfort metric. Sporting a PU midsole that provides a comfy squish, many of our testers noted that it's possible to forget you were wearing this sandal, in a good way. The polyester webbing upper conforms to many different foot shapes, and testers remarked on the lack of pressure points. During long days, the sole feels sturdy enough to support different arch types but maintains a nimble feel.

The biggest drawback of the Clearwater comfort-wise comes from its ankle strap. Because there is not an adjustment point on the ankle, it can be hard to get the shoe on and off. Additionally, varying heel shapes might find discomfort in the ankle strap, as it cannot easily be moved up and down.

With their slip-on, closed-toe style, these sandals score high marks in comfort.

Despite the high comfort scores, this model is not perfect for users who desire an airy sandal. Even though it is remarkably lightweight for such a protective shoe, it still comes with the tightness often associated with a closed-toe model, more so resembling a shoe. The Clearwater isn't as stifling as wearing a hiking boot, but it's still much hotter than most of the open-toed models we tested.

If you are looking for a waterproof sandal/shoe hybrid for river trips, however, this would definitely be our top pick. The snug and comfortable fit and closed-toe design ensure that you will be able to walk on rocky shorelines with ease, and transition seamlessly from water to land and back again without ever having to change your footwear.

Traction

Although this model does not sport a trusted Vibram rubber sole, it's adequate when walking on slabs or pebbly inclines. The Clearwater features a versatile tread pattern that sits somewhere in between aggressive and soft. With that said, some testers felt that the addition of a stickier rubber on this product's sole would bump its traction score up. Its soles are also slightly rounded at the edges, which contributes to a feeling of not as much surface area being in contact with steep slabs, and our testers noticed some considerable slipping in these situations.

Working in chorus with the sole pattern of the Clearwater is its overall design. Because it cradles the wearer's foot, it does a good job of eliminating foot slide within the shoe while descending steep slopes.

Though it is capable of walking up steep slabs, this sandal leaves a little bit to be desired in the traction category.

The Clearwater shines in water crossings, where its protective toe bump eliminates the worry about mashing your toes against rocks. This model provides ok traction over slippery rocks through both the outsole and the footbed but does not perform the best of all the sandal models we tested in this metric.

Adjustability

Although Keen claims that their bungee lacing will work to cradle your foot, our testers did not find this to be the case. The bungee secures the upper and midfoot but not the toes and ankle. This earns it an okay-but-not-great adjustability score.

Despite the low score, testers feel that the design of the webbing straps works well to conform to the foot. There's not much you can adjust, which saves some of the time and frustration that we experienced with other models. We don't, however, recommend this shoe for folks with narrow toes or bumpy ankles. Consider a more adjustable model if that's your anatomy.

The only point of adjustment on the Clearwater sandals is a cinchable bungee cord.

Stability

Like its performance in our comfort category, the Clearwater performs well in the stability metric.

With a TPU stability shank and 4mm of midsole drop, users feel this model offers adequate comfort while giving a good feel of the ground beneath their feet. This is aided by Keen's addition of multi-directional "flex grooves," which work to give natural contact with the ground while allowing for improved interaction between your foot and the ground. Our testers were worried that this would result in painful moments when walking across sharp rocks, but this did not prove to be the case. This sandal does an excellent job of performing as well as a shoe while remaining breathable, waterproof, and lightweight.

These sandals slip on and conform snugly to our feet, and feel like they can tackle many different types of terrain.

Despite this, higher-arched testers felt hung out to dry on very long days while wearing this model. If you have a soaring arch and demand comfort on long days with a heavy pack, consider checking out one of the Chaco models.

Versatility

The Clearwater receives a moderate score here. This model can handle just about anything you throw at it in the backcountry, and testers were excited to take it on nearly any adventure. From water sports to travel, this model works well, but this style is tough to transition into town.

Specifically for water sports, the Clearwater features hydrophobic webbing, allowing for theoretically quick drying time. However, the material that the webbing connects to retains water. This can be a bummer if your hike involves many stream crossings. Also, because of the Clearwater's closed-toe design, when small pebbles find their way inside the shoe, they can be more difficult to remove than from an open-toe model.

The closed-toe design makes this shoe a little less versatile than open-toe designs.

We wore the Clearwater a ton around the backcountry, but we also took it out in town. This sandal is fine for biking, as well as errands and yard work if you like the look.

Style

Compared to most of Keen's models, the Clearwater is sleek and pared-down. However, compared to most of the other sandals we tested, this style is tough to pull off.

You are the best judge of your style, so take a look at the photos in this review and ask yourself if you'd be happy to wear these sandals around town as well as on the trail. Our testers were somewhat mixed on this sandal, but our lead tester found it hard to pair the Clearwater with anything other than hiking pants. The friends and family we surveyed were also less than enthusiastic about the look of this shoe.

While not the stylish sandal out there, these sandals are highly functional and aren't a complete eye-sore.

The Clearwater currently comes in quite a few colorways, mostly pretty neutral, so you can choose a shade that will work best with your personal style.

Value

The Clearwater is on the expensive side, but if you are looking for a durable and comfortable adventure sandal, we think it's worth it. Not only is there more material than most of the other models, but it also serves a broad scope of activities, so you can get a lot of bang for your buck.

Conclusion

The lightweight yet protective design of the Keen Clearwater CNX made it a favorite among our testers and won it a Top Pick Award. This model can take on a huge swath of tasks, from SUPing to hiking to running errands, as long as you can handle the style. If you're looking for a more protective sandal that likes adventure, this is the product for you.

A lightweight yet sturdy sandal fit for many of your adventure needs.
