What Is the Women’s Keen Hyperport H2 ‘Chipmunk/Birch’?

The Women’s Keen Hyperport H2 ‘Chipmunk/Birch’ (Style Code: 1030678) is Keen’s most advanced closed-toe water sandal — the performance evolution of the legendary Newport H2, engineered specifically for women who operate in demanding aquatic and trail environments. Built on a women’s-specific last with quick-dry polyester webbing, a metatomical dual-density EVA footbed, a compression-molded EVA midsole, and a non-marking rubber outsole with razor siping, the Hyperport H2 elevates every performance dimension of the Newport H2 platform with an enhanced athletic construction and a more modern silhouette. The ‘Chipmunk/Birch’ colorway — soft tan with creamy birch white — is the most natural and seasonless in the Hyperport H2 lineup. At $129, it is priced identically to the women’s Newport H2, making it the clear performance-first choice at the same price point.

Specs & Construction

Hyperport H2 vs. Newport H2 — What’s the Difference?

The Newport H2 is Keen’s founding water sandal — introduced alongside the brand in 2003, it has been the gold standard for closed-toe water sandals for over two decades. The Hyperport H2 is the next generation: same closed-toe philosophy, same H2 quick-dry webbing system, same metatomical footbed — but with an enhanced athletic construction, updated last geometry, and a more performance-forward silhouette designed for buyers who push the H2 platform harder. Key differences:

Bottom line: If you want Keen’s most capable and modern water sandal and you use your H2 hard, choose the Hyperport. If you want the classic trusted platform with decades of proven performance, choose the Newport H2. Both are $129. Both share the core technology. The Hyperport H2 is for those who want more.

The Women’s-Specific Advantage

The Keen Hyperport H2 women’s edition (1030678) is built on a women’s-specific last — not a scaled-down men’s last, but a last re-engineered around female foot anatomy: narrower heel cup to eliminate heel slip on uneven terrain, toe box proportioned for female foot shape, and pitch adjustments that distribute weight correctly across the female foot’s contact geometry. In a water sandal context, fit precision is critical: heel slip during a river crossing or a wet rock descent is not just uncomfortable, it is a safety issue. The women’s-specific Hyperport H2 eliminates that risk while delivering all the performance credentials of the platform.

Key Technologies — Explained

Metatomical Footbed: Keen’s anatomically shaped footbed, contoured around the metatarsal arch (the transverse arch across the ball of the foot). Dual-density EVA: firmer under the arch for structural support, softer under the heel and forefoot for cushioning. Removable for custom orthotic users. Meaningfully more supportive than a flat foam footbed during extended outdoor water use.

Razor Siping: Fine blade-cut grooves in the rubber outsole that multiply the number of rubber edges gripping the surface — the same principle used in premium performance tires. On wet rock, river gravel, and slick shoreline surfaces, razor siping provides grip where plain rubber slides.

Non-Marking Rubber Toe Cap: The closed-toe rubber cap protects toes from rocks, roots, and underwater hazards without leaving black marks on boat decks, kayak interiors, or indoor floors. Critical for mixed indoor-outdoor water environments.

Quick-Dry Polyester Webbing: Polyester webbing sheds water rapidly and dries within minutes of leaving the water — eliminating the discomfort, softening, and odor buildup of slow-drying materials. Essential for multi-crossing water use.

The ‘Chipmunk/Birch’ Colorway

Chipmunk is a warm, medium-depth tan — the color of sun-dried driftwood, natural canvas, and the sandy fur of the North American chipmunk (the naming reference). It is warmer than grey, softer than brown, and reads as organic and terrain-matched. Birch is a pale, creamy off-white — the color of birch tree bark, bleached driftwood, and natural linen — appearing as a lighter accent that gives the shoe its two-tone structure. Together, Chipmunk and Birch produce a palette that is the most natural and terrain-coherent in the Hyperport H2 lineup — a colorway that recedes into outdoor environments rather than standing out from them. It pairs naturally with olive, tan, khaki, and earth-tone outdoor apparel, and works equally well in river, trail, and casual summer contexts.

Who Is the Women’s Keen Hyperport H2 ‘Chipmunk/Birch’ For?

This sandal is for the woman who uses her water sandal hard — the river guide or kayaker who crosses water dozens of times in a day, the canyoneer navigating technical slot canyon approaches, the coastal hiker moving over wet rock and tidal terrain, the outdoor instructor on her feet for eight hours across mixed aquatic and land environments. The women’s-specific last makes it the correct choice over unisex H2 alternatives. The Chipmunk/Birch colorway makes it the right choice for buyers who want a water sandal that blends into the natural environment while performing at the highest level the Keen H2 platform offers.

Frequently Asked Questions

Q: What is the style code for the Women’s Keen Hyperport H2 ‘Chipmunk/Birch’?
A: The style code is 1030678.

Q: What is the difference between the Keen Hyperport H2 and the Newport H2?
A: Both share the same closed-toe H2 platform — quick-dry webbing, metatomical footbed, razor-siped outsole, non-marking rubber toe cap. The Hyperport H2 is the next-generation evolution: enhanced athletic construction, updated last geometry, and a more performance-forward silhouette designed for more demanding water and trail use. Both are priced at $129. The Hyperport is Keen’s most capable H2 platform; the Newport is the proven original.

Q: Is the Women’s Keen Hyperport H2 built on a women’s-specific last?
A: Yes. The 1030678 is built on a women’s-specific last — narrower heel cup, female foot geometry — not a scaled-down men’s last. This provides a more accurate fit, reduces heel slip on uneven terrain, and distributes weight correctly across the female foot.

Q: Does the Keen Hyperport H2 fit true to size?
A: Yes, true to size for most wearers. Size up half for neoprene socks or thicker outdoor socks. Available in US Women’s 5–9.5.

Q: Can the Keen Hyperport H2 be used for ocean and saltwater?
A: Yes. Quick-dry webbing, non-marking rubber, and closed-toe protection make it suitable for ocean shoreline, tidal pools, and coastal hiking. Rinse with fresh water after saltwater use to extend strap and hardware life.

Q: What does ‘Chipmunk’ look like as a color?
A: Chipmunk is a warm medium-depth tan — warmer than grey, softer than brown, the color of sun-dried driftwood and natural canvas. Paired with Birch (creamy off-white), it creates a natural two-tone that blends into outdoor terrain rather than contrasting against it.
