• Insoles are a bit thin and lack
customizable arch support
• Not cheap
• Good ventilation
• High-quality construction
Gaerne has a strong reputation in every-
thing from motocross to cycling, producing
some of the highest-quality kicks around.
The Italian company has had its shoes and
boots on some of the world’s fastest ath-
letes. Summer riding in Southern California
is guaranteed to be hot and dusty, and
having gear dedicated to ventilation is key.
The G.Sincro + Summer shoe from Gaerne
is a warm-weather-specific product that we
rode on the hottest days to see if it could
withstand the summer heat.
Tech info: The G. Sincro is made at
Gaerne’s factory in Italy and exudes that
renowned Italian quality. Gaerne uses a
carbon sole with abrasion-resistant tread to
offer riders good traction off the bike and
keep the overall construction lightweight
and stiff. The carbon sole is Gaerne’s
proprietary MTB 3Density sole that is
designed specifically for mountain bike use.
Up front are two threaded holes for riders
to thread in studs if conditions are muddy.
There is additional protection on the front
of the toe to increase durability. Gaerne
uses an injection-molded plastic heel cup
for added stiffness and comfort.
Gaerne relies on a dual BOA retention
system and Tarsal Support System.
Adding to the comfort is a pad-
ded tongue that
extra pressure on the front of the rider’s
foot once the fit is dialed in. These shoes
were designed to increase ventilation, and
the tongue features added vent holes to
help push air through. The paneling on the

On the trail: Out of the box the Sincro
felt noticeably lighter than other carbon
fiber cross-country shoes that we have
tested. The mesh paneling didn’t feel flimsy
or vulnerable to tearing. We installed our
trusty SPD cleats and went
out on the hottest
days to see just
how well the
The dual BOA retention system made
dialing in the fit simple and distributed
the enclosure evenly around our feet. The
Gaernes felt stiff, but not overly so once we
stood and pedaled hard out of the saddle.
The heel cup kept our foot in place and
didn’t give us any unwanted slipping, even
at higher cadences.
Our test riders were impressed with just
how well the G.Sincros breathed, even on
the hottest days. The mesh ventilation
system channeled air through the shoe
efficiently and kept our feet cooler than
usual. While the G.Sincro + Summer is
lightweight and breathable, it could offer
an insole with better arch support. That
said, Gaerne is known for its quality and
durability, and the G.Sincro + Summer
reinforces that reputation. ❏
