CHRONOS 4E — AERO TRIATHLON CYCLING SHOES WIDE-FIT
AERO TRIATHLON SHOES WITH WIDE-FIT 4E DESIGN — LONG-DISTANCE COMFORT. The Cadomotus Chronos 4E are aero triathlon shoes that combine the aerodynamic exterior of the flagship Chronos Aero with a flat carbon sole and wide-fit 4E design. At €199, they bring the aero advantage and long-distance comfort for athletes who need a more accommodating fit than a traditional shell sole.. AERODYNAMIC DESIGN WITHOUT THE SHELL SOLE. Inspired by the Chronos Aero’s wind-tunnel-tested profile — 3–9 watt aerodynamic saving measured at Eddy Merckx Velodrome — the Chronos 4E maintains the same streamlined upper and sculpted closure. A flat carbon sole accommodates narrow and wide feet alike. Enhanced ventilation keeps feet cooler in hot race conditions.. BUILT FOR LONG DISTANCE: The flat carbon sole optimises power transfer across the full foot width. Heat-moldable design eliminates pressure points that build up over 90–180km. Sockless fit from T1 to T2 — without the fit restrictions of a high-wall carbon shell.. Aerodynamic upper: Streamlined profile based on Chronos Aero wind-tunnel design. Flat carbon sole: Stiff power transfer for a wider range of foot types. Enhanced ventilation: Improved airflow — optimal in hot race conditions. 4E wide-fit design: Roomier fit for narrow and wide feet alike. Heat-moldable: Custom fit for sockless long-distance comfort

CÁDOMOTUS TRIATHLON CYCLING SHOES
ENGINEERED FOR TRANSITIONS.
Cádomotus is the only brand in the world that engineers cycling shoes exclusively for triathlon. Not adapted from road cycling, not borrowed from track — built from scratch around the demands that make triathlon unique.
Cádomotus is the only brand in the world that engineers cycling shoes exclusively for triathlon. Not adapted from road cycling, not borrowed from track — built from scratch around the demands that make triathlon unique.
At the heart of every shoe is CarbonShell™: a monocoque carbon construction that wraps around the entire foot, developed over 25 years of engineering elite speed skating boots. In speed skating, athletes corner at 60 km/h on a 1.1 mm ice blade, barefoot inside a carbon shell. That same precision now powers every Cádomotus triathlon shoe.
You don’t just ride faster. You arrive better. That’s Transition Performance.

WHY CÁDOMOTUS?
CarbonShell™ is the only triathlon shoe sole you can heat-mold at home. Ten minutes in the oven, and the carbon shell adapts permanently to your foot anatomy. The result: a fit so precise you fly out of T1 without even closing your shoes. The molded shell holds your foot in place from the first pedal stroke — no shifting, no hotspots, no fiddling with dials while the pack rides away.

A lower sole platform reduces calf strain during the bike leg. A rigid CarbonShell™ sole supports the entire foot, eliminating energy loss from flex in conventional shoes. The muscles you save are the muscles you need most for the run. This isn't marketing — it's biomechanics. → Read the science
