Clearwater CNX
Keen
The Keen Clearwater CNX takes the proven protective design of the brand's classic water sandals and strips away the excess bulk. Designed for paddlers, rafters, and wet hikers who want real toe armor without the clunky, heavy feel of a traditional utility sandal, the Clearwater delivers a low-profile, nimble ride that fits far more comfortably inside narrow kayak cockpits. Built on a low-drop platform with minimal midsole stack height, the Clearwater allows your foot to sit closer to the ground, significantly improving your balance and trail feel on uneven river terrain. The multi-directional flex grooves in the sole allow your foot to bend naturally, while the razor-siped outsole rubber opens up under flex to grip damp river stone. The upper utilizes lightweight polyester webbing lined with quick-drying mesh, anchored by a quick-cinch bungee lace system. The weight savings come with a few compromises. The toe bumper, while fully functional and effective, is thinner and less armored than the tank-like guard found on the Newport. The streamlined sole also provides less cushioning and puncture resistance against sharp river rocks, meaning your feet will feel fatigued earlier if you are navigating a prolonged, rocky portage trail carrying heavy expedition loads. **Highlights** * Low-profile 4mm drop midsole connects you closer to the ground for better agility * Outsole flex grooves with razor siping for dependable wet-surface friction * Streamlined rubber toe guard provides essential protection without added bulk * Quick-cinch bungee system provides rapid and reliable tensioning * Lightweight design fits comfortably into tight kayak hulls **Watch-outs** * Thinner sole transfers more sharp-rock pressure during heavy carries * Open side construction still permits small pebbles to enter beneath the foot * Lighter webbing offers less lateral stability than heavier heritage models

Whisper
Keen
The Keen Whisper is engineered specifically for women who need a capable, toe-protected water sandal with a narrower last and softer flex than unisex or men's platforms. It is ideal for flatwater touring, recreational kayaking, and river walking where comfort, drainage, and toe security take precedence over brutal trail portaging. The upper features narrower polyester webbing straps that conform cleanly to lower-volume feet without creating the excessive puckering or loose heel gaps common in wider sandals. Elastic bungee lacing secures the fit with a single pull, while the soft hydrophobic lining minimizes chafing when the shoe is fully saturated. Keen's signature toe bumper is present, keeping your toes protected during rocky beach landings and river wades. Underfoot, the Whisper utilizes a cushioned, compression-molded EVA midsole that delivers immediate out-of-the-box comfort for day outings. However, the outsole compound and lug pattern are oriented more toward sand, gravel, and packed dirt than greasy, algae-covered whitewater boulders. If you submerge the Whisper into deep river muck, the softer sole and flexible webbing will stretch slightly, offering less structural resistance against foot slippage than more rigid expedition sandals. **Highlights** * Tailored fit designed specifically around a lower-volume, narrower foot shape * Integrated rubber toe guard shields against shoreline and riverbed impacts * Elastic bungee lace capture system allows rapid, one-handed fit adjustments * Soft hydrophobic mesh lining prevents rubbing against bare skin * Lightweight, flexible sole offers easy packability for travel **Watch-outs** * Outsole rubber lacks razor siping for slick, algae-covered rocks * Lighter webbing can stretch slightly when fully saturated in heavy mud * Less underfoot arch support for long hikes with heavy expedition gear
