Cushioning for Comfort: The soft latex foam in Scholl's Air-Cushion insoles helps to provide additional comfort by cushioning the impact when your foot hits the ground. They can help breathe new life into old shoes. Trim to Size: The Air-Pillo insoles can be individually trimmed to fit every size shoe. When cutting, use sharp scissors to ensure that there is no fraying of the edge. The insoles will not be damaged when cutting is done carefully. Breathable insoles: These insoles are perforated to allow your feet to breathe and moisture to escape.
