SiDi Size Guide
Buying the right sized shoe can be tough when you buy online. Knowing
your size helps, but sometimes the sizes are not the same across
different brands or in different countries. Our size guides are designed
to address two aspects of the sizing issue
- SiDi shoe sizes compared across UK, EU and the US (Chart A)
- SiDi shoe sizes compared across popular shoe brands such as Adidas, North wave and Pearl Izumi (Chart B)
These SiDi Size charts are generally very helpful and our customer care
is always at hand to offer further advice. Our one and only advice is,
always buy shoes that fit comfortably out of the box. SiDi hand builds
its shoes from fixed ‘lasts’ (otherwise known as moulds). There are
basically three lasts - standards (men’s), Women’s, and the Mega
(wide-fit). The same lasts are used for the construction of SiDi’s entry
level shoe as their premium shoe.
SiDi has a great reputation for having the comfortable fit right out
the box. So any discomfort is most likely linked to choosing a shoe that
doesn’t fit… we advise you try another size.
Remember, SiDi shoe sizes are not ‘smaller’ they are simply more
‘precise’. The design is focused on providing highly competitive riders
with shoes that do not move once they are on your feet. The fit is meant
to be snug, the shoes designed to cradle your foot closely. This
doesn’t mean that your toes should be squashed in any way, but it does
mean that if you wearing a looser fitting shoe in another brand that
size may be too large for you anyway.
Wide feet and high arch
For people with wider feet and higher arches, finding the right size
can be difficult. A bigger size of shoe will mean a loose fit and a
standard shoe might feel tight around the base of your toes or the
SiDi has designed its Mega shoes for every size, with about 0.5cms (0.2 inches) width in the areas where
a wide foot is broader. Consequently, if you wear size 44 and find it
slightly tight around the front or under the arch, then a 44 Mega might
be the solution for the perfect fit.
Vent Carbon Sole
The 2013 Vent Carbon Sole is an engineering marvel—stiffer and lighter than SIDI’s all-conquering Carbon Lite Sole, with integrated vents and air channels for heat dissipation and improved comfort. The 2013 Vent Carbon Sole now features a NEW ultra-light heelpad and a NEW replaceable integrated toe pad/vent cover. It is specifically engineered for high-performance, high-mileage cyclists.
Like all of SIDI’s hand-lay-up carbon soles, the Vent Carbon Sole is constructed in an Italian contract facility that specializes in carbon fiber fabrication, and includes speed merchants Ferrari and Ducati on its client list. It is handmade exclusively of T700 carbon fiber in a 3k weave pattern (competitors’ carbon soles have little carbon fiber content, or use cheaper, lower-modulus T300 carbon fiber), oriented at opposing angles that maximize stiffness while allowing for a small degree of controlled flex in the toe area that biomechanically relieves stress on the plantar tendon and helps promote circulation. The sole is heat- and compression-molded with longitudinal corrugations that improve mechanical stiffness without added material or weight.
The Vent Carbon Sole is not only light but remarkably stiff, deflecting only 1.4 mm in SIDI’s rigidity test, in which a 50 kg (110 lb) weight is suspended from one end of the sole.
The vent features a sliding cover for four-season comfort, and leads to two longitudinal airflow channels molded into the carbon sole that direct air underneath the forefoot area’s perforated footbed (SIDI’s Comfort-Fit insoles have matching perforations for unimpeded airflow).
The Vent Carbon Sole features a standard 3-hole drilling pattern, printed 10 mm lateral and fore/aft cleat alignment scale as well as the Look Memory Eyelet for easy cleat alignment and replacement.
For triathlon, the vent also serves as a water drain, dramatically improving foot comfort after a wet transition.
Soft Instep Closure System
The Soft Instep Closure System is a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area. The Soft Instep Closure System is adjustable from both sides, to perfectly center the EVA pad over a high or low instep. Excess strap on the crank arm (inside) side of the shoe may be trimmed after adjustment. Like most SIDI small parts, the Soft Instep Closure System® is replaceable.
Tecno 3 Buckle
In 1966 Mr. Dino creates the first ever mono-filament line closure system with a rotor buckle for use on the ski boots of the Italian Olympic Champion Marielle Vautcel. In 1988, 22 years after inventing the mono-filament line closure system with a rotor buckle, Mr. Dino patents it for use in a cycling shoe. The patent covers a closure placed on the heel as well as on the instep. Three adjustments are shown: tightening across the instep, across the forefoot, and around the heel.
The latest version of that system, SIDI’s NEW Tecno 3 buckles, adjust fit across the forefoot and the toe of the shoe. The precision ratchet closure mechanism is easily adjusted using two buttons that can be pressed to incrementally loosen the buckle, one ratchet tooth at a time. Lift and turn the center buckle to tighten the shoe. To open completely, push on both buttons while pulling on the soft instep closure system. SIDI’s famously reliable and replaceable closures are improved by an ALL NEW proprietary SIDI Wire material, an extremely supple braided synthetic material that’s very low friction, for completely non-binding action and extremely even pressure distribution across the closure.
Like most SIDI small parts, the Tecno 3 Buckle is serviceable and replaceable.
Adjustable Heel Security System (HSS)
The Adjustable HSS, introduced in 2006, reinforces the top of the heel cup and adjusts to securely close around the heel just above the calcaneus (heel bone), eliminating power-robbing heel lift during the pedal stroke.
Like most SIDI small parts, the Adjustable HSS is replaceable, and also available as an aftermarket upgrade to 2007 thru 2009 SIDI models.
Lorica is an exceptionally soft, supple microfiber synthetic leather possessing all of leather’s positive attributes, without any of the attendant shortcomings. It is water-repellent, quick-drying, breathable and permeable to water vapor, making it an ideal material for shoe uppers. It is abrasion- and mildew-resistant, and resists stretching and deterioration from atmospheric agents.
Sidi Heel Cup
The SIDI Heel Cup is an external, reinforced cup that stabilizes and supports the heel, with an anatomically shaped plastic design holds its form and doesn’t break down over time, helping reduce heel slip and increase power transfer.
