About Geox
Geox is an Italian footwear company founded in 1995 by Mario Moretti Polegato, who invented the patented breathable sole after puncturing holes in rubber soles during a walk in the Nevada desert. The micro-porous membrane lets vapor escape while blocking water.
How Does Geox Fit?
Geox shoes run slightly large with a roomy, comfortable fit. First-time buyers often find they need half a size smaller. The Nebula sneaker range is the most oversized. Uomo Symbol dress shoes are closer to true size. Womens styles run about half a size large.
Sizing Advice
Consider going half a size down for your first Geox purchase. The brands roomy fit is intentional for all-day comfort. If between sizes, go with the smaller size. For narrow feet, definitely size down. Try with the socks you plan to wear regularly.
Width & Fit Characteristics
Geox shoes have a wider, more accommodating fit than most European brands, making them excellent for wide feet. The Nebula range is especially roomy. Formal Uomo styles are narrower. Womens styles tend to run particularly generous in width.
Popular Models
The Nebula (breathable active sneaker), Uomo Symbol (formal breathable loafer), Amphibiox (waterproof boot), Spherica (360-degree breathability), and Myria (womens casual) are Geoxs key lines, all featuring the patented breathing system.
