From the Spherica Collection. Spherica™ EC4.1 is a trailblazing sneaker for women with a supremely comfortable breathable design as well as a contemporary aesthetic. The perfect match to laid-back city dressing and athleisurewear, it boasts an upper in nappa and metallic leather that rests on an on-trend chunky outsole. The classic Geox rubber sole is based on an exclusive patent: the combination of the perforated sole and the resistant breathable and waterproof membrane allow for natural temperature regulation, thereby creating the perfect microclimate inside the shoe that keeps feet dry and comfortable for the whole day.
