An individually moulded insole with 5-mm medial arch support reduces peak impact and loading at the heel after a one-hour treadmill run.

Background: Foot pain experienced by long-distance runners could be relieved by functional insoles which aim at evenly distributing the plantar pressure.

Research Question: We hypothesised that an individually moulded insole with medial arch support would reduce the impact and loading under the heel and metatarsal regions.

Methods: Twelve male recreational runners ran on a treadmill at 10 km/h for 1 hour with flat insoles and medial arch supported insoles.
