Semelles

Semelles, commonly known as insoles, are inserts placed inside footwear between the foot and the shoe’s inner sole. They can be removable or built into the shoe and are designed to improve comfort, fit, and function. Insloes may be plain cushioning or include therapeutic support, and they are available in various sizes and shapes to accommodate different shoe types.

Types and materials vary widely. General cushioned insoles use foam or EVA for soft padding, while orthotic insoles incorporate arch support and alignment features to influence foot mechanics. Sport-specific insoles aim to enhance stability and energy return, and some are heat-moldable or customizable. Materials range from foam and gel to cork, leather, and combination layers, with options for moisture management and odor control.

Functions and applications include improved comfort for everyday wear, reduced friction and pressure, shock absorption, and correction or support for conditions such as flat feet, plantar fasciitis, metatarsalgia, or overpronation. Custom insoles are often prescribed by podiatrists or orthotists and may be created from foot impressions or digital scans, providing tailored arch height and contour.

Care and lifespan vary by material and use. Many insoles should be replaced every several months to a year for regular use, sooner in high-wear shoes. Cleaning typically involves removing loose debris and hand-washing or wiping with mild solutions, avoiding prolonged soaking. Proper fit is essential, and insoles should be trimmed to size to avoid folding or bunching inside the shoe.
