Setup, Compatibility & Care
To ensure the longevity of your Glycerin Flex trainers, it is essential to allow the midsole foam to recover between runs. Avoid storing them in direct sunlight or extreme heat, as this can degrade the nitrogen-infused cushioning over time. If they become wet, stuff the interior with paper towels to absorb excess moisture and air-dry them naturally; do not use a tumble dryer or heat source. These shoes are compatible with standard orthotics if extra volume is needed, though the stock insoles are designed to complement the shoe's cushioning profile.
