The biggest storm in years swept through Colorado in February. Big fluffy flakes just kept falling until over 50 inches of new snow blanketed the backcountry. Skiing that frothy cold smoke over five consecutive days pushed my body to its absolute limit. After day two, I had to drop some weight from my ski touring kit — I swapped in La Sportiva’s new ultralight Kilo boots. But no way was I leaving my biggest, burliest powder skis at home.
Ski touring boots in the 1kg realm typically pair best with shorter, narrower, lightweight skis. Big skis like my 122mm underfoot 4FRNT Renegades can feel unwieldy without some heft at the helm. But in the right conditions, like those that struck Colorado in February, the Kilos can take on more than their fair share of ski. That meant more laps surfing the deep stuff and less fatigue.
Why bother with such a featherweight instead of something beefier? Swapping to the Kilos from my daily driver, backcountry boots dropped over 2 pounds from my feet where you feel that weight the most. Their massive range of motion meant longer strides and less micro-friction that added up after 20,000 steps.
The Kilos are La Sportiva’s sportiest new ski touring boots. And while they may look similar to some of the brand’s competitors, a handful of design elements make these boots stand out from the crowd.
In short: La Sportiva Kilo ski touring boot is a new platform from the boot tinkerers at La Sportiva. These boots, named for their scant weight, manage to do an awful lot with just a little. So much so that they don’t find themselves out of place very often in the backcountry — from skimo racecourses to deep powder; skinny skis to big ones. But of course, the Kilos are specialized backcountry boots. They aren’t beefy enough for lift-serviced skiing or 50/50 resort/backcountry ski setups.
If you’re shopping for backcountry ski boots, compare the La Sportiva Kilo to the hybrid boots in GearJunkie’s guide to the Best Ski Boots.
