The use of Spriing arch supports should not have an impact on foot odour. It is important to maintain good foot hygiene practices and clean / air shoes regularly. Avoid placing Spriing arch supports in shoes that are already soiled or smelly, as this will affect your Spriing arch supports. If your shoes can be cleaned, do this prior to placing your Spriing arch supports in your shoes. If not, it might be time to replace your shoes. Avoid heavy use of chemicals and sprays to mask odour, as this can affect your Spriing arch supports, and in some cases cause skin irritation. Never use disinfectants, sanitiser or bleach on Spriing arch supports as it can damage the materials.
