Hyperport H2
Keen
The Keen Hyperport H2 represents a modern redesign of the brand's classic water sandal, focusing on high-rebound cushioning and reduced overall weight. It is engineered for paddlers, river rafters, and active summer hikers who love the security of a closed toe but want a softer, more energetic ride underfoot for long days on hard river gravel and dirt roads. The core of the Hyperport is its thick, high-cushion EVA midsole. It absorbs rock impacts and trail shock far better than low-profile water shoes, shielding the bottom of your feet from bruising over sharp cobblestones. The upper utilizes lightweight polyester webbing anchored by an engineered bungee lockdown, giving you a spacious fit across the toes without losing security at the ankle. Drainage is rapid through the large lateral windows. While the extra cushioning feels great during portage carries, the higher stack height creates a slightly less stable platform when side-hilling or traversing slick, angled river bedrock. The outsole features Keen's dependable siped rubber, but the thicker foam sole lacks the ground-level sensitivity that whitewater paddlers prefer for boat feel. It works best as an all-terrain river crossover sandal for moderate-to-rough portaging. **Highlights** * High-stack, cushioned midsole delivers superior shock absorption on rocky trails * Generous, wide toe box paired with a protective rubber front bumper * Lightweight polyester webbing sheds water quickly and reduces overall weight * Quick-draw bungee lacing delivers fast, reliable tensioning * Multi-directional siped rubber outsole provides dependable wet-surface grip **Watch-outs** * High midsole stack height reduces ground feel and lateral trail stability * Bulkier profile takes up more room under kayak decks * Large openings allow gravel and river pebbles to enter easily

Loyak AC
Astral
The Astral Loyak AC (Air Conditioned) is a minimalist, low-profile water sneaker that excels in tight cockpits, on paddleboards, and across muddy portage routes. Built to look and feel like a casual deck shoe, the Loyak AC hides serious river-running credentials behind its clean, low-bulk silhouette. The standout element is Astral's G.15 high-friction rubber outsole. It utilizes low-profile, razor-siped lugs that maximize surface contact on slippery boulders, wet wood, and damp boat hulls. The 'AC' designation indicates an ultra-breathable, ripstop mesh upper that promotes maximum airflow and expels water rapidly through dedicated drainage grommets at the toe and heel. Because it sits flat against your foot with minimal stack height, you get unmatched feel and control inside a kayak. The trade-off for this nimble profile is limited underfoot protection. The sole is thin and flexible; if you are carrying an expedition-weight canoe across a jagged, boulder-filled portage trail, you will feel the sharp points of rocks directly under your feet. It is not an alpine hiking shoe, but for paddlers who prioritize boat fit, top-tier wet grip, and fast-draining performance, it is an exceptional tool. **Highlights** * Super-sticky G.15 rubber outsole provides incredible grip on wet rocks and boat decks * Ultra-breathable ripstop mesh upper dumps water and dries rapidly in the sun * Built-in drainage holes at the toe and heel evacuate trapped river water instantly * Ultra-low stack height fits easily into low-volume whitewater and sea kayak cockpits * Secure lace-up design stays firmly on your foot in thick portage mud **Watch-outs** * Thin sole transmits sharp-rock pressure during heavy-load carries * Minimal arch support makes it less ideal for high-mileage overland hikes * Soft rubber outsole wears faster on dry asphalt and coarse trail dirt
