The Carrera XC4 is Saucony’s super lightweight, elite level racing flat, designed for cross country runners.
The weight is kept down by an ultra light, super flexible midsole. The plush engineered mesh upper is also super light and thin, but keeps the midfoot locked down with an ISOFIT system. This creates a stretchable upper that adapts to the shape, size and movements of the foot, to give a sock-like soft feel.
The midsole foam is SSL (standing for Saucony Super Light) EVA foam, the most premium midsole foam in their range, designed to maximise rebound and durability whilst remaining as light as possible.
The full length outsole plate give the shoe torsional rigidity and traction on all racing surfaces.
