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
