AKU Flyrock Mid GTX Women's Black/Silver

AKU Flyrock Mid Gore-Tex Women's (AK697) – Black/Silver

342g per half pair in a mid-cut build — the ankle wrap and debris protection of a higher shoe, without the weight overhead of a traditional trekking boot. The Flyrock Mid Gore-Tex Women's in Black/Silver runs a textile upper with welded PU reinforcement, Gore-Tex Most Breathable membrane for full waterproofing at maximum output breathability, and a Vibram Megagrip + Traction Lug outsole built for wet rock and technical off-trail ground at pace. Dynamic Fit adjusts heel tension as your stride and terrain change. The step up from the Flyrock Gore-Tex (low cut) for days when the route crosses from trail to open fell — and you want the mid-cut ankle to match it.

WHY YOU'LL LIKE IT

• Vibram Megagrip + Traction Lug outsole — maximum wet friction and mud clearance at fast-hiking pace, with the Megagrip compound holding grip on wet rock and slick trail surfaces where grip failures cost more than time
• Gore-Tex Most Breathable membrane — full waterproofing with the most breathable Gore-Tex variant, keeping internal moisture in check during high-output days on the hill where a less breathable lining traps heat and starts to feel wet from the inside
• Dynamic Fit heel tension system — adjusts heel hold dynamically as your stride changes across varied terrain, keeping the shoe planted and responsive without manual lace adjustment mid-route
• Mid-cut ankle wrap at 342g per half pair — 42g more than the Flyrock Gore-Tex Women's (low cut, 300g per half pair) for ankle support and debris exclusion; the 42g step-up worth making when the day combines good trail with open fell or off-trail ground
• UK 3–9 including half sizes

BEST FOR

• Fast hikers who want the Flyrock family's speed-oriented build with a mid-cut ankle for routes that mix good trail with open fell, scree, or off-trail terrain in a single day
• Women targeting long high-output days — Munro days in mixed conditions, fell traverses, Bob Graham prep — where ankle support and sustained grip matter and a sub-350g weight budget is non-negotiable
• Hikers who need Gore-Tex waterproofing without the heat retention of a More Seasons membrane: Gore-Tex Most Breathable runs cooler under aerobic effort, making it the right choice when pace is constant and internal moisture is the real enemy
