Position the Triad so the elevated arch support rests against the inside edge of the shoe and with the molded heel against the back. The support with the Triad log fits into your right shoe. If orthotic slides, peel off covering from tape strips on the bottom of the support and press firmly into shoe. Important: the break-in period for the Triad Orthotic is usually 24-48 hours. Unlike full insoles, Triad orthotics are 3 4 length to allow toes to move freely inside shoes and prevent cramping.
