To ensure a precise level of fit, we recommend removing the existing insole from your shoes and measuring the length and width at the longest and widest point. These foot-specific insoles are designed and shaped to add support for pain relief. They are ideal comfort insoles for individuals that require extra support due to a condition such as flat feet and fallen arches. The Pro11 Plantar Series Insoles realign the body to correct over-pronation, which can prevent pain in the ankles, knees, hips and lower back, as well as relieve heel and arch pain. The use of these orthotic insoles can also ease and reduce pain caused by plantar fasciitis, metatarsalgia, heel spurs and shin splints. The Pro11 Plantar Series Orthotic Insoles are full-length orthotic insoles designed to add support and re-align the body. Their use can relieve foot pain, add support and correct over-pronation to reduce ankle, knee, hip and lower back pain. Other conditions aided by the use of these insoles include Morton's neuroma, bunions, flat feet, fallen arches and heel spurs.
