Yes, you can wash them gently by hand occasionally. Spriing covers are NOT machine-washable. To clean Spriing covers, simply wipe them with a warm soapy cloth, gently rinse with cool water. Air dry before putting them back into the shoes. Avoid washing them too often, which may cause them to degrade more quickly. Once every 2-4 weeks should suffice. Prevention always works best. You can help keep Spriings in good condition by ensuring you only ever place them in clean shoes free from soiling and wear them with clean dry feet.
