Setup, Compatibility & Care
Because the Glycerin Flex utilizes a technical knit upper and a performance midsole, proper care is essential to maintain the shoe's longevity. Always ensure the laces are adjusted to provide a secure fit without restricting circulation. Compatibility is best for neutral runners; if you require orthotics, the cushioned sockliner can typically be removed to accommodate custom insoles. To clean the shoes, avoid machine washing or drying, which can compromise the foam integrity and glue bonds. Instead, use a soft-bristled brush or a damp cloth with mild soap to spot-clean the upper, and allow the shoes to air dry away from direct sunlight or high-heat sources to prevent the midsole foam from degrading.
