The Nike Flex Supreme TR 4 cross-trainers are built to withstand prolonged use due to their lightweight and flexible construction. Specifically engineered for long-term activity, the Flex Supreme TR 4 GS ‘Dark Grey’ delivers the same essential design features found in the adult sneaker, but now in a kids’-sized version. The sneaker is equipped with a textile mesh upper, complemented by a breathable lining and strategically cut quarter panels that seamlessly merge with the lacing system. To provide utmost comfort, the sneaker is placed on a Phylon foam sole, ensuring cushioned strides.
