Setup, Compatibility & Care
Ensure you are using the correct UK sizing, as the Glycerin GTS 23 has a structured, performance-oriented fit. For optimal care, avoid putting the trainers in a washing machine, as this can break down the adhesives and the integrity of the foam cushioning. Instead, wipe the mesh upper with a soft cloth and mild soap. If the shoes become soaked after a run in the rain, remove the insole and stuff the interior with newspaper to draw out moisture slowly. Always store them in a cool, dry place away from direct heat sources to prevent the midsole from warping.
