The Cadence Original Orange provides contoured semi-rigid orthotic support and exceptional shock-absorbing comfort under the heel and forefoot. The Original Cadence helps alleviate and prevent common injuries such as plantar fasciitis, metatarsalgia, shin splints, iliotibial band syndrome, achilles tendonitis and other conditions of the foot, knee, and hip. The Foam is approximately 7mm thick at the heel and under the ball of the foot before tapering to 5mm at the toes. For most accurate sizing and optimal fit, choose the insole size that most closely matches your foot size.
