The SEW Midsole™ has the property of being less prone to harden even in low temperature environments. It promotes comfortable exercise by reducing the decline in cushioning properties and flexibility even in low temperature environments.


Hardening of the midsole in low temperature environments has been prevented by combining a material with low hardness variation against temperature.


The conventional E.V.A. midsole hardens in low temperature environments, resulting in low cushioning effect. To overcome this problem, the SEW Midsole™ has been developed using materials less vulnerable to temperature change.
