The Cosmic Ultimate IV shoes are designed for riders who want to feel every watt being transferred through the drivetrain.
The Matryx® upper, made from Kevlar and polyamide fibres, has very low stretch to minimise energy loss, whilst remaining breathable.
The Matryx® weave incorporates ventilation zones and reduces the use of adhesive.
The BOA® Fit System with Li2 dials allows separate adjustment of the tightening zones, with micro-adjustment in both directions.
Underfoot, the full-carbon sole features a new rigid design and incorporates openings to ventilate the forefoot.
Weighing 245g, the Cosmic Ultimate IV shoes are designed for racing, warm-weather runs and long-distance efforts.

Ventilated Matryx® jacquard, reduced use of adhesive, underfoot vents: coolness in hot conditions
The Matryx® Jacquard places ventilation openings on the upper, where heat builds up.
Reduced adhesive minimises air barriers. Underfoot, the openings integrated into the carbon sole promote continuous airflow to the forefoot.
