| The Hydro GTX features an insulated, waterproof Gore-Tex® upper that keeps feet warm and dry
no matter how bad the weather gets. The slightly roomier fit accommodates a heavier winter
sock as well as SiDi Toasters. Four Velcro straps keep your feet secure.
Millennium 3 Sole
By fortifying the sole with carbon fibre,
SiDi designers have
created a sole that improves on the
technical characteristics of the previous nylon
sole. The Millennium 3
sole is constructed out of injected carbon fibre
in a nylon matrix. The infusion of which
gives the sole 36% more rigidity than the
previous Millennium 2 sole. The Millennium 3
sole is also more durable and less susceptible
to changes in stiffness resulting from prolonged
usage and changes in temperature. It
is compatible with the best road pedals on the
market. To facilitate cleat replacement, the
Millennium 3 sole features a 10 mm horizontal
and vertical cleat alignment scale molded into
the sole as well as the Look Memory Eyelet.
Replaceable
Heel Cup
A replaceable spare
part that prolongs shoe life way past that of
the competition.
