Understanding “FIT” notes:
ALL KURU shoes are sold in US sizing. IF the “FIT” note says “1/2 size small”, you should purchase a 1/2 size larger than your normal size (e.g if wear an 8, purchase an 8.5). If the note says “1/2 size big," then purchase a 1/2 size smaller than your normal size.

It’s the perfect walking shoe. Designed with a wide, stable base, breathable comfort, structured stability, and a roomy toe box, QUANTUM is one of our fan favorites.
Our heels take a beating, but they don’t have to. QUANTUM is built with our patented, heel-hugging KURUSOLE technology. Unlike anything else, KURUSOLE dynamically flexes to hug and protect your heels, helping prevent foot pain conditions such as plantar fasciitis.
Keep sweat at bay all day long. QUANTUM’s airy mesh uppers and moisture-wicking linings help your feet stay dry—from workouts to dog walks.
