How to Measure
It's easy to find the right shoe size, just place both feet (in your normal riding socks) on a piece of paper and carefully draw the outline of each foot. Make sure you keep the pen pointing straight down to get a true outline! Then measure the lengths of both outlines from the top edge of your big toes to the back edge of your heel. If your two feet measure differently, take the longer of the two measurements and that's your size - all measurements in centimetres (cm).
Helpful Hint
Remember to wear your normal riding socks and if you ride around the year you might want to make a bit of allowance for thicker winter socks.
REPLACEABLE SHIN PLATE: Shin plate are easily replaceable trough screw.
BUCKLE AND STRAP: This closure system adjust to the leg circumference on both sides therefore increasing the opening of the boot for ease of putting on.
ANKLE SUPPORT BRACE and AIR VENTILATION SYSTEM: The two nylon braces join the ankle joint with two screws that are hidden by a nylon cap. This system supports the ankle and is reinforced with fiberglass and is easy to replace. This system allows excellent flex movement front-to-back while being firm side to side. On the outer lower part of the boot an air intake is fitted which can be operated by an aerodynamic shaped button.
ZIP ELASTIC PANEL: Sidi has added a small elastic panel to aid in a smooth zipper operation as it allows a bit of movement via the elastic as the zipper passes over the rider’s ankle ball.
REPLACEABLE SLIDER: The slider is replaceable and available in full nylon, with ceramic or with aluminium inserts.
SHOCK ABSORBING HEEL CUP: A polyurethane shell holds a shock absorbing insert, visible from the outside through small slits that mark out the look of the heel. The shell is mobile as it is fixed to the boot by two screws that allow 3 mm of impact movement.
TOP SOLE: Rubber top sole.
