My husband wore these once at the gym for a workout but needs a bigger size. The Primus Lite Knit’s flexible knit upper, made with recycled plastics, adds even more mobility and agility to the beloved Primus Lite. The same 2mm Primus outsole, with an Active Ortholite Performance Insole made of 98% recycled PU foam, makes it perfect for active lifestyles and controlled workouts.
