Ice climbing often presents challenges beyond just facing the elements; the right footwear can make all the difference. The La Sportiva G-Summit boot is making waves among climbers, promising comfort and adaptability whether scaling vertical ice in the Canadian Rockies or tackling mixed routes in Norway.
Design innovation in the G-Summit caught the attention of three testers, including the author, who all have different foot shapes. Last winter, they faced demanding climbs like Carlsberg Column and Polar Circus, reaching altitudes of 10,000 feet in frigid temperatures. "Despite all three testers having notably different shaped feet, all of us raved about the boot’s comfort," the author noted, raising an intriguing question: what makes the G-Summit so universally enjoyable?
Upon taking the boots out for an extensive test, it became clear that the G-Summit offers a unique flexibility, functioning as both a single and double boot depending on conditions. Climbers can switch between a standard 5mm thermal insole or a more streamlined 3mm inner boot. This adaptability allows climbers to customize their fit. "The G-Summit’s BOA system has a big range—much larger than other BOA boots I’ve tried—in order to achieve a snug fit at both of these notably different volumes," said one tester. This innovation caters perfectly to various foot sizes and shapes.
One impressive aspect the testers highlighted was the lack of heel-lift experienced in the G-Summit. "For climbers with narrow, low-volume feet like me, the G-Summit is the only boot I don’t experience heel-lift in. Life changing," the author remarked, reflecting on the significance of a secure heel fit for effective climbing.
Comfort extends beyond fit. The BOA tightening system allows climbers to adjust their boot easily mid-climb. "Boots feel a little baggy mid-pitch? Quick tighten. No blood circulation once you get to the belay? One click open and they immediately loosen," the author explained, emphasizing the boot's versatility in performance under pressure. Throughout a wide variety of climbs, none of the testers reported developing blisters, a testament to the boot’s engineering.
The G-Summit's single-or-double design also proved advantageous during approaches. "Often I’d swap the liner sock for the insole (or even a supportive orthotic) to provide a less-warm option for sweaty hikes uphill," the author added, showcasing its adaptability for different climbing scenarios.
When it came to warmth, the G-Summit stood tall, boasting more insulation than the La Sportiva G-Tech single boot. However, it may not achieve the same warmth as the G2 or Scarpa’s Phantom 6000. Nonetheless, this makes the G-Summit an excellent choice for the Canadian Rockies or northeastern climbs during deep winter.
Durability is a key component of any climbing gear, especially when faced with rugged terrains. "After a ton of use, the G-Summit suffered minor wear and tear: a bit of rand peeling, a tiny crack in the toe-cap, and some scuffing where stiff plastic met rock," noted one tester. At $929, its robustness is considerably impressive, especially given the wear and tear of challenging climbs. The sticky rand offers reliable grip when needed most, allowing climbers to navigate tricky sections without worries.
However, a word of caution is warranted regarding the external BOA system. "If you do break one off—as one tester did in an old pair of La Sportiva G5s—they are too finicky to replace on the side of a mountain," warned the author. This potential point of failure may lead climbers to prefer the traditional lace-up system.
The La Sportiva G-Summit boot has proven itself a worthy contender for ice climbers seeking an adaptable, comfortable solution that accommodates various foot shapes while performing reliably in extreme conditions. As climbers reflect on their experiences, this boot has established itself as a staple for serious ice climbing adventures, earning accolades amid the competition, and signaling a bright future for those scaling icy heights.
