The Prince NFS Rally squash shoes feature the NFS (Natural Foot Shape) design that guarantees superior fit. The shoes are suitable for indoor court surfaces and have been engineered to provide maximum comfort and stability. To provide lightweight shock absorption and reduce fatigue the shoes utilise the EVA midsole and removable moulded EVA sockliner. Additionally, the shoes' lightweight synthetic upper has breathable mesh panels to provide good ventilation. Good traction on indoor surfaces is delivered by the gum rubber outsole.
