This new super-lightweight range raises the bar with a higher closed-in heel, enhanced vents, SSR sole intelligence and optional, removable insole. A refreshingly ergonomic design created in collaboration with biomechanics researchers from the University of Salford, the SSR slip resistant soles, adjustable heel straps for forward or behind heel fitting, and anti-static, shock absorbing heel maximises all day comfort. You can machine wash them at 40° C for added hygiene. CE certified.
